Braking Output

Tekonsha Prodigy P3 brake controller

Braking output is the maximum amount of power that will be applied to your trailer's brakes. How much braking output you need is determined by the weight of your trailer; a heavier trailer will need more power to bring it to a stop. Use the arrow buttons on the front of the module to set the output. You want to set the braking output as high as you can without locking up the brakes. Once you've set up the brake controller the first time, you shouldn't need to adjust this setting unless the trailer load changes, you switch trailers, or road conditions change. The LCD display will show the current output setting being used.

Tekonsha Prodigy P3 review

Power Boost for Heavy-Duty Towing

The boost setting controls the aggressiveness of your trailer's braking, meaning how quickly the brakes reach the maximum braking level. You can adjust this when you're towing heavy loads and you need more umph to bring your trailer to a stop. Your tow vehicle doesn't need that much power to brake in time, but your heavy trailer does.

Depending on the level of boost, your trailer brakes can start at either 13 percent or 25 percent of the set braking output. What this means is that, instead of starting at 0, the brakes will start at 25 percent and get to100 percent sooner. This keeps the trailer from pushing your tow vehicle forward.

If your trailer weighs less than your tow vehicle, no boost is needed. But, if you want your trailer to lead the braking, you can select level B1.

Boost Levels:

Approximate Gross Trailer Weight Boost Level Increase in Initial Power Output
Less than tow vehicle GVW B1 13%
Equal to tow vehicle GVW B1 or B2 13% or 25%
Up to 25% more than tow vehicle GVW B2 or B3* 25%
Up to 40% more than tow vehicle GVW B3* 25%

*Both B2 and B3 offer a 25-percent boost in initial power. But the braking curve for B3 is more aggressive than that of B2. This means that, even though you will start out with the same intensity when using these boost levels, you will get an overall more aggressive braking experience with the higher level. So if you use B3, you will reach maximum braking sooner than if you use B2.

Storable Settings

Customize the P3 and store your settings so that you can easily access them later. If you tow multiple trailers, or the same one but with differing loads, store the desired boost and power levels for each so that you don't have to completely reset the controller every time you switch between trailers. It's easy to swap between drivers as well. Program the P3 display with your desired screen color, brightness, and language, and you can easily return it to your preferred settings the next time you tow.

Customizable LCD Display and Advanced Diagnostics

The P3's LCD display features a distinctive look with multiple color and contrast options. With lots of customized options, you can change the display to make it easy for you to see and check your braking status at a glance.

Safety Features

The Prodigy P3 offers advanced safety features to prevent damage to various components of your towing setup. Integrated reverse battery protection shields the brake controller and your trailer's breakaway system from shorts. When the P3 is not in use, it will be in power-saving mode. In this setting, it draws only 3.6 milliamps, minimizing drain on your vehicle's battery.

The P3 also comes equipped with a hold feature to prevent wear on your brakes. When you're waiting at a red light, you don't need your trailer brakes on at full power. The longer you sit there, the more they will overheat. But with the P3, any time your tow vehicle and trailer are at a standstill with the brakes applied for more than 5 seconds, the hold feature will kick on and reduce power to just 25 percent. This will keep your trailer in place while saving your brakes.

The P3 keeps the manual override within easy reach, great for stopping sway or controlling your trailer's momentum in emergencies. To engage the manual override, just twist the rotary-style lever from right to left. This will activate the trailer's brakes and brake lights without you having to apply the brakes on your tow vehicle, perfect for limiting trailer movement while you're cruising.

Automatic Leveling and Simple Installation

The self-leveling feature of the P3 ensures that the brake controller continues to function even as you drive up steep hills or through the mountains. Simply mount it in your cab at any vertical angle, and the controller will level itself automatically thanks to its 360-degree rotational range. This makes the installation that much easier. But keep in mind that the P3 must be horizontally level and parallel with the direction of travel to work correctly.

Correct P3 mounting 360-Degree P3 mounting

Installation is a snap. After mounting the P3 unit in your cab using the included bracket, hardwire one end of the included pigtail harness directly into your vehicle. The other end plugs into the brake controller. To remove the P3 for storage when you're not using it, just unplug the unit and slide it out of the bracket. With a replacement wiring harness (sold separately) and replacement bracket (TK5906 - sold separately), you can even transfer the Prodigy P3 to another vehicle.

Installation Accessories

For even easier installation, a vehicle-specific specific wiring adapter (sold separately) is available for most newer trucks and SUVs. One end of the custom adapter plugs into your vehicle, and the other end plugs into the controller - no hardwiring required.

See also's exclusive 7- and 4-way brake-control installation kit (ETBC7 - sold separately) if you don't already have a 7-way plug at the back of your vehicle.

Note: If a custom brake control wiring adapter is not available for your vehicle, one of the following will be required:

20-Amp circuit breaker (9506P - sold separately) for 2- to 4-brake applications

30-Amp circuit breaker (38630 - sold separately) for 6- to 8-brake applications

Proportional Braking

What is proportional Braking

The Tekonsha Prodigy P3 brake controller comes equipped with proportional braking to give you the best towing experience. Proportional braking means that your trailer brakes mimic your tow vehicle's brakes. If you slam on the brakes in your vehicle, your trailer brakes will activate with the same intensity; if you brake lightly, your trailer brakes lightly too. The trailer's braking is in proportion to your vehicle's braking. This saves wear and tear on the tires and the brakes on both your vehicle and trailer.

The Prodigy P3 uses an internal inertia sensor to detect how your vehicle is braking so it can send the right amount of braking power to your trailer. It measures the inertia of your tow vehicle and activates the trailer's brakes to slow at the same rate. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.

This Tekonsha Prodigy P3 was recommended to be by a friend who works at an RV dealership service center. This is my fifth trailer brake controller over a forty-year period, and my first progressive controller. I really love this controller. My truck has a factory towing package, but was manufactured prior to inclusion of integrated controllers. Since the truck has factory towing, the installation was very simple. The installation instructions were clear and complete. I would definitely recommend this controller to anyone looking for a dependable, easy to install and easy to use controller.

After a year of use, I am very happy with my beak controller. I would purchase this controller again, without any hesitation. I highly recommend it.

I mounted my Tekonsha P3 on the dash just to the left of the steering wheel. Has very easy access to quickly activate the lever on the bottom of the unit to apply maximum trailer brakes. But I needed a wiring harness almost double the length of the Tekonsha Wiring Adapter so I just purchased two and spliced them together to make one long one......yea I could have saved money and just sliced in longer wires....Am very happy with the Tekonsha P3, With this mount it makes it easy to disconnect and put into my Ford F150 or my Tacoma.

Still lovin it! Works Great!

The Prodigy P3 came on just as the instructions said it would. Although I have not used it yet it looks good in my ‘15 LX. I look forward to great service towing my 20’ flat trailer with tractor, rotary cutter and box blade. My to the staff at etrailer.

Rodigy P3 brake controller works good. It is especially helpful on the nearly mile long descent to the low water bridge crossed on the trip to the Woodz where I spend time maintaining the deer hunting acreage.
Dennis - 08/29/2022


The support bracket for this is unacceptable because the standoff from the dash is more than 1" and it puts the controller against my right knee. The mount for the controller in your video was almost flush against the dash and that's what I thought I was getting.


Top quality brake controller. Automatic leveling. Get the wiring harness for your tow vehicle. This makes installation easy.


A year ago, I switched from a "dumb" brake controller to this computerized one with numerous features. It really gives you proportional control, and knows to ease off as you come to a complete stop (my last controller would always give me a good jerk at the end of a stop).

Other features include letting you know if your cable is not making a proper connection with your trailer (if it comes out of the receptacle or you forget to connect it, you get a big red "No Trailer" message on the screen. That might help you avoid damage, embarrassment, an expensive repair, or a tragedy.

Been using this for a year, and still very happy with the purchase. Not the cheapest brake controller at $160, but I think this one might be the best. And the peace of mind and smooth braking is worth it.

I have a 2018 BMW X2 that did not come with a factory tow package. I had an etrailer hitch and 4 way plug installed last year and has been perfect since. I just recently purchased a camper and needed to have a Brake controller & Brake controller 7 way deluxe kit installed. My mechanic installed them with the detailed instructions that the units came with without any issues. The Tekonsha P3 is extremely user friendly and is working flawlessly. A bit overkill for my car being I can only tow max 3500 pounds, and my camper is 1 axel. this unit is rated up to 3 axles. I look at it like this way, when I trade in my BMW I will take my P3 with me. etrailer is amazing with the support & products they provide and I highly recommend them to anyone who asks me.

Love the P3, so easy to use and will be using this on my next vehicle when I trade this in. Highly recommend this unit.

It does not progressively apply the trailer brakes it’s all or nothing! Very disappointed! I bought this controller because it was supposed to work with the electric over hydraulic trailer brakes and yes I have it on the correct settings for my triple axle double deck car trailer. Because it doesn’t progressively apply the brakes I have had to replace nearly new tires because of flat spots. If you have any suggestions I’m all ears!

It sounds like the Boost Setting not the actual power adjustment on your Tekonsha Prodigy P3 might just need to be changed. The boost setting allows for more aggressive braking. I recommend to turn that down or off and see if your braking is smoother.

I purchased and I installed the Hydrastar Disc Brake Kit HSE7K-T1 along with the Prodigy P3 brake controller on my 42'fifth wheel. As the saying goes "why did I wait so long" , I have been running them for a few months now, I wanted to get some miles and testing on the system before I commented so after several roads trips now about 4000 miles I am very pleased. They have worked flawlessly. I have always been on edge when towing, especially in the mountains with the old electric drum brakes. Now I have so much more confidence in stopping and that lifted so much stress off me. The old electric drum brakes just never felt as if they would stop the trailer especially in an emergency stop, but now if you apply the brakes hard you can feel the trailer stopping the truck. I have never been able to lock up the tires on the camper till now.
If you have a little mechanical knowledge the installation is not difficult as long as you plan things out and be patient.
I did have a few hiccups with shipping and a few parts but thanks to Robert all issues were addressed and corrected ASAP and parts were shipped out to me immediately. A special shout out to Robert which answered so many of my questions and helped me with ordering everything I needed to install my kit. etrailer has always been a pleasure to work with. I will never have an RV without Disc Brakes again. Thanks again to Robert and etrailer.


Unit worked great tested with load force meter . Good out put . Always powered with key off . Hot in Vegas so will disconnect when not in use


Great aftermarket trailer brake control ler.


Purchased the P3 for a 2020 Ford Ranger. A few days after install, I was advised by service Tech that the P3 is not approved for the Ford ranger due to lack of accommodation for the Ford Ranger anti-collision system. In an emergency braking issues generated by the system. The Brake controller would not sense that braking leading to a possible accident. The only brake controller approved by Ford is the Redark Tow pro which has an extra wire that ties into the 3rd brake light which is activated under system generated emergency braking. After a run a round, E-Trailer refuses to refund or correct the problem and apparently accepts full liability for any injuries, death or property damage that could occur due to the issue. Redark Tow Pro Elite - The only FORD APPROVED trailer brake controller compatible with all vehicle safety systems including:

Forward Collision Warning System
Automatic Emergency Braking


An updated product that works extremely well. I moved a 35’ travel trailer with my 1 ton pickup After making sure the trailer breaks were in working condition, setting the controller to the appropriate voltage for stopping percentage, the system operated perfectly. The trailer was centered very well so there was no sway. But when braking was required, the system worked perfectly. Easy to install and with the plug adapter for my pickup, it was “plug and play”. Well done, Tekonsha and many thanks You folks always seem to come up with the right product at a great price just when I need it…thanks again…


The Tekonsha Prodigy P3 works better than any brake controller I've ever owned. Because there is a connection to the brake light circuit, even the slightest pressure on the brake pedal results in trailer braking action. Braking action becomes progressively stronger as one continues to apply pressure to the brake pedal. This, of course, is all adjustable to suit your specific needs and preferences. Less sophisticated brake controllers require measurable slowing of the tow vehicle before the brake controller will apply any braking action to the trailer. In my opinion the Prodigy P3 offers the smoothest and safest trailer braking available.


The Tekonsha Prodigy P3 was highly recommended for a brake controller for the trailer I purchased. Was easy to install especially with the special adapter to connect to the vehicle wiring system. It does take some time to fine tune the vehicle with the trailer for braking but when you hit the sweet spot it's great. Highly recommend this brake controller!


I bought the P3 to replace my factory integrated brake controller. Factory controller cannot deal with hydraulic disc brakes on new fifth wheel. Installation was fairly easy on my 2010 Ram 3500. However the Dodge dealer could not get rid of the service message that appears on truck display after factory integrated brake controller was unplugged. I gave dealer the printed instructions from etrailer on how to do it, but dealer says instructions incorrect.

The Dodge Dealership will be needed in order to get rid of the error, since they will be needing to disconnect the ITBM for you. In order to disconnect the ITBM and not get the warning lamp, your local Dodge dealer will have to reconfigure the TIPM Totally Integrated Power Module, of the truck. Once that is reconfigured, then the ITBM can be unplugged.

First, a huge "Thank You" to Janice!!! You are the best, and the main reason I am the proud owner of Tekonsha P3 Brake Controller! (see, I initially had an issue with my standard online payment service and almost canceled my order because of it) So I went old school and picked up the phone, one with a cord and spoke to a human being. Her name is Janice, and she made me feel confident that I could trust her and etrailer. And as a result, 4 days after placing my order with her I received my package. That's incredible. I am very happy and will most certainly do business with etrailer again in the future because of Janice.

I don't have any experience with brake controllers. So I can't really comment on how much better or worse this one is to any others. But since I am new to the B/C scene maybe this can be considered an unbiased, non professional review of the Tekonsha P3.
My general skill level is "requires supervision around all power tools". But I do have some mechanical ability (snicker). So I will just say, if I could install this thing anyone should be able to do it. Of course I also bought the OEM wiring harness for my vehicle so even I was able to figure out which plug went where. On A scale of 1 to 10 I give it a 3 (I'm somewhat large and getting under the dash wasn't easy or it would be a 1). And as others have said, deciding where to mount it actually took longer.

I attached mine to the top of the lower dash cowl and it fits almost tight to the dash but still within the 180 degree limit. This positions the controller at the same height as my knee and puts it within fingertip reach while resting my hand on my knee. I can see the controller perfectly through the steering wheel spokes. I went with the green screen background. it seemed to provide the best view in all lighting conditions.

The controller itself works perfectly and the set-up was a breeze. Once installed all the functions worked as described. The real time vehicle diagnostics are a plus. I like being able to monitor my battery voltage to the decimal place if I want to. I'm sort of a techno geek so this is really cool. I set the B/C voltage per the instructions and will only use the boost feature if I am in a hurry or feel the trailer is at max load, but my truck is 8k lbs so you may want to set yours to suit your own conditions.

I highly recommend the Tekonsha P3 brake Controller if you want the latest and probably the best controller out there in this price range. I highly recommend the OEM wiring harness if your skills are not pit crew comprable and want the easiest install possible. And, I highly recommend you buy it from etrailer if you want to get it at the best price available (I checked them all) and want the added security you're buying from one of the best online retailers that sells this product. And do yourself a favor, go old school for a change, use the phone and call them, and ask for Janice, although I'm willing to bet everyone there is as nice as her.

How long is the wiring harness? I want to mount the brake controller on the right side of my steering wheel. It looks short in the picture. Thanks! Tom

Prodigy 3 is our go to brake controller. We've been using it successfully for many years towing our 19' Escape and our 30' Airstream Classic. Works really well in our Sprinter 2500 and our GLS 580 tow vehicles.


Installed this on my GMC 3500 Duramax with factory integrated brake controller. Not happy with the integrated brake controller on my truck, had problems from the start on 3 different occasions with "Service Trailer Brake" warning on DIC, which of course means NO TRAILER BRAKES. Decided the P3 was the perfect solution. Many more features than the IBC, plus the P3 will also work with electric over hydraulic disc brakes should we ever need that in the future. Fairly easy install on this particular truck, the most difficult thing was running the brake wire from the controller to the 7-pin plug. (This is only required when installing in a vehicle with a factory installed brake control) Well worth the extra effort.

Recommendation...dont mount it to low out of reach. When you have a trailer go astray...your seat belt will tighten and then you cant reach your controller to help you out. Believe me I mounted my too low and out of reach, and I was seconds from ditching the truck and trailer. Was very lucky. Just a recommendation.

I recieved my brake controller quickly. It arrived in a padded envelope with a small hole in it. Opening the envelope, the retail box that holds the brake controller was open and parts spilling out into the padded envelope. I am concerned that it may be damaged, but I do not have my trailer yet. Who ships a flimsy box with a $xxx electronic item in a padded envelope? Why not a box?? Shipping is an area for reviewing!!

Installed P3 this weekend in 2013 Tundra Crewmax with towing package and pre-wire. Extremely easy, even with the center console installation. Will let the photos tell the story. Did have to combine the P3 included harness with the additional OEM harness to gain the length I needed. Plug and play with the pre-wire. Hooked up to trailer and set boost levels for varying loads. Works great! Vast improvement over older model Tekonsha controller in my Ram 2500 Diesel. Pull a Kiefer BP horse trailer: about 3600 lbs empty, 7500 with 3 quarter horses and gear. Usually pull 6-8 times per year, with only 1-2 horses. Short distance and flat terrain. It took about an hour to install. Dad is a retired USAF/FAA radar technician with every tool known to man. He QC'd the job. Will try to write better review later.

how hard is it to remove small center console plugin great installation thanks Mark
-- comment by: mark d - 11/14/2013
To remove the small center console cubby hole you need to open both 12V outlets, then using your thumb and index finger, slowly work the cubby out. I used a very thin straight edge screwdriver to get it started as well. Helps to have two people. Once out, I used a rotozip tool to cut the back out. I thought I could get away with simply drilling a hole for the wires, but you will need more room. Recommend leaving a lip on the bottom edge where you cut out so small items dont fall behind your dash. Hope this helps.
-- comment by: Chris M - 11/26/2013
Great write up Chris M. I just mounted mine and would like to make one note about the little yellow clips that hold in the console. They are very good at making a quick exit to some unknown location but I was able to fine the Toyota part number incase someone may need it. It is 90467-10203. They cost about a dollar. I got lucky and finally found the one I lost and saved myself a dollar.

Continues to work perfectly, Purchased a second one recently for another truck, very pleased with both brake controllers, easy installation & works seamlessly with my GMC trucks & trailers


I had to build a custom bracket for the controller mount since the X is limited in under dash metal but the install went well. The 7 pin trailer harness is a factory Nissan part (plug and play) , but since the receiver does not have the any mounting brackets, I positioned the 7 pin connector up and out of the way of harm by drilling and flush mounting it in the rear bumper. Thanks for carrying products relevant to your customer's needs and having products that work right. I have attached some pics from the finished install. I will be ordering accessories as I need them from your company as you have always been prompt, thorough and very courteous in all of your correspondence.

Is this a pathfinder, I need to add a 7 way connector do you have any photos of yours.? Id like to see wear you put it

Hi, I got my Item: 90195 and shipping was fast. I was able to get the break controller installed in my 2012 Cadillac Escalade Luxury using the video guide for a 2009 Cadillac Escalade. The install and wiring was the exact same as the video however my wires under the dash or wire bundle did not have a wiring sticker. The color of the wires were the same as in the video. This etrailer video is great and I used it to get my controller installed in about 1.5 hours. My install was trouble free.

This weekend I was able to test out the my new P3 90195 controller and get it calibrated with my 29 foot travel trailer this weekend. Used a B2 setting with 8.0 power. The user guide and instructions you get with the controller help you know what settings to use and how to set the power level.

This is my second controller as I got a P2 Tekonsha from etrailer about 4-5 years back and installed it in a 2007 trail blazer. This older 2P break controller is still working great. I have been rather happy with the quality of the Tekonsha controllers I have. I have not had to call etrailer for support or install questions but did receive a few emails from them to check in with me to ensure I got my shipment and offer me help. They do a good job supporting and responding to their customers and provide an A+ customer experience.

All good on my end. The controller is working with no issue. Getting ready for our 6th camping trip this year. Thanks for your follow-up.

I was looking for a controller to put between my motorhome and car trailer.
I was a bit leery of the P3 unit... not because of the unit itself but because of my lack of confidence in installing it. Did not really want to be cutting and connecting wires. After doing some research on the etrailer website and elsewhere online, I discovered that my motorhome probably had a pre-wired harness ready for the Ford/Tekonsha adapter. A quick check... it did and I ordered the P3 with the adapter. Installation took about 30 minutes... most of which was me wedging my large body in place to connect the adapter and then spending another 15 minutes debating where to locate the P3. Actual connection and installation time was 5-7 minutes.

The P3 fired up correctly and setup was simple and straight forward. We took off for the hills of southern Ohio - not exactly the Rockies but also wouldn't want to head there without trailer brakes. The P3 performed flawlessly and we were glad to have it. I didn't realize it when I bought it but the P3 has the ability to preset up to 5 variations of trailer/load combos which will come in handy as we switch back and forth from towing cars to motorcycles. Easy to install, easy to operate, peace of mind while towing.

  • Display on Tekonsha P3 Remains Lit Once Vehicle is Shut Off
    After 15-20 minutes of no movements the Tekonsha P3 like most brake controllers, will go into a sleep mode. While in the sleep mode, the controller will draw a minuscule amount of voltage that is nowhere near enough to run down the battery even after several weeks. The brake controllers are specifically designed not to have an on/off switch because the fear is that if the controller is turned off the user could forget to turn it back on and unintentionally end up towing with an inoperable...

  • Wire Labels of Brake Controller Wiring 2016 Chevy Express Explained
    Yes, the circuits you found for installing the P3 part # 90195 that you referenced in your 2016 Chevy Express Van are correct. The CHMSL circuit stands for center high mount signal lamp and is a dedicated brake light circuit and runs to the red wire and then the blue wire of the controller goes to trailer auxiliary circuit.

  • Does Prodigy P3 Brake Controller Eventually Shut Itself Off With No Activity
    After 10 minutes of inactivity the Prodigy P3 part # 90195 will go into sleep mode which means it basically shuts itself off without losing presets.

  • Is 30A Relay Required to Use Tekonsha Prodigy P3 Brake Controller with 2015 Audi Q7
    It is true that the older version of the P3 # 90195 and older vehicles that have varying voltage on the brake signal required a 30A relay system to help with compatibility. I reached out to my contact at Tekonsha and he said that while the newer P3 and newer vehicles, like your 2017 VW Touareg and your 2015 Audi Q7, interact better with the brake controller and you might not need it, he recommends installing one anyways just to be on the safe side of things. We don't have any relays that...

  • Troubleshooting Flashing Blue Screen on Tekonsha Prodigy P3 Brake Controller
    Thank you for all of the info that you provided. From what you described I believe you have a wiring issue going on. If everything tested out just fine for the P3 # 90195 after you installed it on your 2011 GMC Sierra then it leads me to believe that the problem lies on your trailer wiring as opposed to the installation of the brake controller. If you jump to page 10 of the instructions for the P3 (which are linked to this page for you to check out) you can see that there are multiple...

  • Troubleshooting Prodigy P3 on 2012 Toyota Tacoma Where Brakes Do Not Lock With Manual Override
    Since everything seems to be functioning correctly otherwise with your new Prodigy P3 # 90195, I would start by examining the brakes; this could be a magnet wiring problem and if the wiring is not properly connected it could cause the brakes not to fully engage. Make sure that the magnets are properly grounded to a clean, bare metal surface free of corrosion. A bad ground on the magnets would not allow the circuit to be complete and lead to the brakes not performing like they should. With...

  • Does Prodigy P3 Brake Controller Plug into 2013 Tiffin Allegro With Powerglide Chassis
    To install the Tekonsha Prodigy P3 Trailer Brake Controller # 90195 on your 2013 Tiffin Allegro Bus you will need to hardwire it in as there is not a port that allows it to plug in. We have previously confirmed with Tiffin that there will be four wires under your driver's side dash that have butt conectors on them, and you will use these to wire in the Prodigy brake controller. The wires from the Prodigy are going to be Black for power, Blue for brake controller output, Red for stop light...

  • 2010 Subaru Outback 2.5L Towing and Tongue Weight Capacities
    You are safe to tow up to the full rated capacity of your 2010 Subaru Outback 2.5L. The online owners manual states a maximum loaded trailer weight of 2,700 lbs with a maximum tongue weight of 200 lbs. The manual states this is 8% of the maximum trailer load with is definitely on the low end. Most trailers will have 10-15% of the weight as tongue weight so you will need to be cautious in how you load the trailer to make sure you are within both total weight and tongue weight capacities...

  • Brake Controller on 2020 GMC Acadia Only Sends Power to Trailer Brakes with Manual Override
    It sounds like you have a proportional brake controller, like the Prodigy P3 # 90195, installed on your 2020 GMC Acadia. Since a proportional brake controller uses an internal inertia sensor to help determine how much power to send back to the trailer brakes it won't send any power when you are sitting still. That's why you're able to apply the brakes with the manual override and not with the brake pedal. The lights for your trailer are actually on separate circuits from the trailer brakes...

  • Can Switch be Installed on Power Wire of Prodigy P3 Controller to Keep it From Draining Battery
    Technically you could install a switch on the black power wire of the P3 # 90195 to keep it from drawing power, but the problem with that is that when the power is removed it loses all of it's settings. The P3 draws very little power when the vehicle is off and it would take a few weeks of the truck just sitting there for the brake controller to drain the battery so unless you're only going to be using the vehicle a few times a month then there won't be a real benefit to adding that switch,...

  • Troubleshooting No Power on Blue Brake Wire for Brake Controller on 2016 Ram 3500
    There are a few things to check when our brake controller isn't sending power to the 7-Way and starting with the fuses on your 2016 Ram 3500 is a good choice. Since all your fuses look good and you still aren't getting power the next thing to check is to make sure that we are testing the blue wire about 6" back from the brake controller. This lets us know if it's the brake controller or if there is a problem with our brake circuit between the controller and our 7-Way. If you still aren't...

  • How Does Brake Controller Install on 2017 Tiffin Allegro Red Freightliner
    To install a brake controller like the # 90195 on your 2017 Tiffin Allegro Red you will want to use the brake controller port that will be to the left of the steering wheel under the dash. Unfortunately we don't have a connector that plugs right into this. The actual part number for that connector from Freightliner is PAC 12064754. This part should work for all Freightliner Chassis from 2004 to 2017. The connector is a 6 wire connector with a cap on it. I attached a photo showing it with...

  • How to Bypass Factory Brake Controller on 2008 Chevy Silverado
    The best option for you to by pass the factory brake controller is the Tekonsha Prodigy P3 Trailer Brake Controller part # 90195 which has storable settings to save the brake settings for more than 1 trailer. Since you tow a 5th wheel and an utility trailer this is the most convenient option since you won't have to change the settings every time you tow. The Tekonsha brand controllers are very reliable and you won't have to worry about losing braking power with the P3. The brake controller...

  • Installation of Brake Controller on 2020 Ford Transit T250
    I was able to determine the correct wire for your 2020 Ford Transit T250. You will want to connect the red wire of your Prodigy P3 # 90195 to the brown wire with green tracer. This is the cold side of the brake switch so it will only get signal when the brake pedal is pressed.

  • How to Remove Wiring Harness from 90195 Tekonsha P3 Brake Controller
    You can detach the harness from the Tekonsha P3 brake controller by gently pulling up on the tab shown in the photo while pulling rearward on the connector. You'll want to do this gently, so the tab doesn't break. The same holds true for all the Tekonsha brake controllers.

  • Troubleshooting Prodigy P3 Brake Controller that Shorted Out and Blew Vehicle Fuses
    The P3 part # 90195 does not have a reputation for failing and causing the types of problems you are encountering but it's not totally impossible for that to happen. I'd be more inclined to believe that a trailer wiring short caused the brake controller to fail which then caused fuses to blow as the controller then shorted out the vehicle wiring. Again, this is not a common occurrence and the best I can do is speculate from here. So returning the controller under warranty is the route...

  • Troubleshooting Low Power to Trailer Brakes form New Brake Controller on a 2007 GMC Sierra
    It sounds like you are using a proportional brake controller like the Prodigy P3 # 90195 on your 2007 GMC Sierra. If this is the case then there is an internal inertia sensor that helps to determine how much power to send back to the trailer brakes. Since your pickup is sitting still when you apply the brakes with your foot the brake controller and tell that the vehicle isn't moving so it only sends a little power. When you use the manual override it sends max power even though you aren't...

  • What Do the Codes on Screen of Prodigy P3 part # 90195 Indicate
    In general the Prodigy P3 part # 90195 uses full words for messages on the screen, but there is are codes for the boost settings which basically is a way to increase sensitivity of the controller. For those you'll see letter codes of B1, B2, and B3. The letter E on the screen is for being set into electric brake mode. If it shows an H it's in electric over hydraulic mode. Pretty much anything else will be a full word on the display. If you have a different controller let me know and I'll...

  • Troubleshooting Prodigy P3 Brake Controller that Blows Truck Fuse When Connected
    It's very possible the P3 # 90195 that you have was damaged and now has a short that fries the fuse your truck has for a brake controller. This would be a rare occasion for this to happen as the P3 is normally really reliable, but based on what you've tried already I'd say it's pretty likely at this point. I think connecting a different controller like you mentioned would be a great way to hone in on where the problem is. I'd try that to see what happens and then go from there. I did...

  • Troubleshooting Weak Trailer Brakes
    Sounds like your trailer has self-adjusting brake assemblies that just have reached full adjustment yet. What you can do is apply the manual override lever of the controller several times while you are at parking lot speeds and eventually they will be the correct tension. Or if they are manual adjust brakes you would need to set them to correct tension. You want to tighten them up so that they lightly drag when spun by hand. Check out the video (see link). Beginning at the 4:23 mark,...

  • Troubleshooting Prodigy P3 Brake Controller Install Where Truck Fuse Keeps Blowing
    Did the older Reese brake controller use the same harness that your P3 used? Or did it use a separate harness from the P3? If that's the case I'd say somehow there's a short there causing problems. The fuse blowing indicates that the power wire for the controller is shorting to ground so most likely there's somehow a short between the black and white wires of the brake controller wiring which at this point seems to point towards the harness.

    According to the troubleshooting directions, the Er code that is showing on your Prodigy brake controller indicates that there is an internal brake control problem. You can try unplugging it for a few seconds and plugging it back in to reset it and see if that clears the code but if not it's time for a new controller. The P3 part # 90195 that you mentioned would be a great option for an upgrade. It has the same functionality as the P2 but has a display that uses full words instead which...

  • Trailer Parking Lights Not Functioning with 2013 Ford F-350
    Most likely you have a bit of corrosion or dirt on the pins of your trailer connector that needs to be cleaned off with a bit of sandpaper. Try doing that and let me know if you see any improvement as corrosion is almost always to blame for trailer wiring issues! I also attached a help article on troubleshooting trailer wiring issues as well.
