Gain Power Adjustment

Tekonsha Prodigy P2 gain

You can adjust the gain (also known as output) with the thumbwheel on the front of the controller. Gain lets you set the maximum amount of power that will be applied to your trailer's brakes. A heavier trailer will need more power to achieve smooth, safe braking, while a lighter trailer will need less. Typically, the gain is only readjusted when you experience changing road conditions or if the weight of your trailer changes.

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 gain. 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.

Safety Features

The Prodigy P2 offers key 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 P2 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 P2 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 P2, 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 P2 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.

The Prodigy P2 also offers diagnostics such as:

  • Open ground
  • Overload
  • Output short
  • Power loss
  • No trailer connection

Automatic Leveling and Simple Installation

The self-leveling feature of the P2 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 P2 must be horizontally level and parallel with the direction of travel to work correctly.

Prodigy P2 correct mounting

Installation is a snap. After mounting the P2 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 P2 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 (P7685 - sold separately), you can even transfer the Prodigy P2 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 P2 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 P2 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.

the controller has great reviews, I got it because my factory controller wasn't working well with the new camper that has electric/hydraulic brakes and I was experiencing a 5 second lag for the trailer brakes to come on. this controller works better with a 2 to 3 second lag, need to try a couple different combos on settings, have the boost at 3 (per recommendations) and gain at 2.5 and under hard braking it locks up the trailer tires. going to try boost on 2 and bump up the gain and see if that works better.

Has doing this corrected the lag?
-- Etrailer Expert Katrina B - 05/19/2023
That worked a little bit better, it seems as though the brakes are either off or locked up. If I set the gain to more than 3 the trailer locks up the tires, if I adjust the gain down a little then it seems like they don’t come on at all. A very small window. Same with the factory integrated controller.

Just installed it. My Camper is a restored 1966 Frolic with electric brakes that I am getting checked out tomorrow.
Unit installed fine on my Chevrolet Colorado and the actual installation video with the Colorado was perfect!
Thanks - I will recommend it to a friend who needs to do the same on his Silverado.

Excellent product and the install instructions were perfect on you tube or wherever I found them
Joseph - 05/25/2023


Used it for a season’s worth of towing camper with my 2015 Chevy Traverse LTZ and it works great. Easy to use and effective. With a controller installed there is a big difference in braking; right away you could tell that the camper was braking and taking a lot of load off my Traverse. Good product, and easy to install on my vehicle that has a OEM tow package. Installed nicely right up under the right side of the steering wheel, mounted on the lower plastics.


This is the second P2 brake controller. Smooth dependable breaking. Item arrived quickly and price is very good.

No problems at all with this unit. Dependable and smooth braking while pulling fully loaded trailer.
Earl - 05/16/2023


Probably a great product like the other equipment I have purchased and installed from etrailer. This particular brake controller instructions directed me to connect to a wire coming out of a multi wire plug up under the dash board of my 2002 Toyota 4Runner. There was no way I could get my hands to the wire let alone conect to it. So I will look for the brake light wire running to the rear of the vehicle and splice onto it.


The brake controller is pretty easy to install and use.the installation video is very helpful and the written instructions on the website is great they specifically point out the size of the studs saving a ton of time trying to locate nuts to make the finally connections.


Easy installation on my Ford E-450 Bus! Now I can pull my travel trailer! Thanks!

Still works after a year! It really has done a great job! Thank you!

Installed this in my 2015 Jeep Wrangler Unlimited Sport. I thought that I would add some input on installation that would help others.
I found a way to route the power distribution wires in the frame of the Jeep that did not require the use of a fish tape. If you look at the frame just behind the rear tire you will see a hole in the face of the frame. Start pushing the wire bundle foreword. It will rise up and over the U shaped frame portion of the rear axle and then down along the passenger compartment area. About there, you will be running out of pushing stiffness. Look for the wire bundle to appear at a similar hole in the frame in that area. Grab it a and pull out approximately 4 feet and then push it right back in the same hole going foreword. This time you will look for the wire bundle to appear at again a similar hole just foreword of the driver compartment. Now is the time to grab it and start heading up to the engine compartment outside the frame. Do the same procedure for the wire going aft for the plug end of the installation. For the wires going through the firewall, Jeep has conveniently added a nice foam lined hole to route wires through. You will see this hole position in the attached photo with a green wire coming through. The plastic cover around the steering column pulls down from the top and hinges at the bottom. Remove the metal plate with two bolts to get to the brake switch. Twist and pull the brake switch out foreword and go for the brown stripped wire as your brake circuit. Do order the LONG frame bracket adapter for the switch plug at the rear. To drill the steel for the supplied plug bracket just takes too long. Now that you have it installed you will notice that the power will remain on the unit after you turn the key off. Don't sweat this as it will not stay on long. I doubt a few milliamps draw is going to kill your battery!

Working great would recommend to all.

This is the second one I purchased. The first was 10 years ago and installed in my 06 GMC. It has worked flawlessly allowing for safe and smooth stops from normal braking to a few of the panic stops that had to made over the years. The new owner of the truck likes the way it works too. I have multiple trailers and with one initial setup on the lightest trailer was able to tow all of them without changing anything but the boost setting to compensate for the different trailer weights.
When needing for a controller for my 07 Silverado there was no other unit that would fill the bill. This P2 looks the same except for the blue display instead of the red. The install took 20 minutes using the direct fit cable ordered with the controller. Setup was easy as with the first unit. I wanted the placement above the parking brake pedal so the OBD II connecter had to be moved. I did the same with the 06 GMC. It is a comfortable place to reach and it keeps the light away from the passenger's eyes at night.
As good as the Tekonsha controller is it is even a sweeter deal buying it from etrailer. The quick shipping, excellent pricing and knowledgeable staff are second to none in customer service.

Tekonsha recently updated the Prodigy P2 with an auto-dimming feature for the display so no more worries about being blinded at night.
-- Etrailer Expert Mike L - 02/14/2019


Video installation instructions were extremely helpful. Everything was plug and play once one had gained access to the hidden factory connectors.


The online video showing the installation of the Prodigy P2 trailer brake control into a 2011 Ford Ranger was excellent! It made the installation into my Ranger simple and straight forth.
I have yet to hook up to my travel Trailer and adjust it for brake setting, but all readout displays thus far are as stated in the instructions.
Having previously installed the trailer connector, I did not purchase the installation kit and in retrospect for cost effective and simplicity would recommend anyone to purchase the kit along with the controller.
I believe I am going to be very pleased with this product.
Thank you

great! thank you for an excellent product!

I haven't used the controller yet, but it seems pretty solid and installation wasn't difficult. It would be nice if Tekonsha explained the pinouts though. I had to rely on the generic diagram found here:


very nice controller, very smooth and you don't have to mount it flat!! e trailer is the best company i ever worked with. they have pics, video, email support(exellent) and just flat out make it easy for you to do it yourself instead of paying some dirt bag $300 to install at your local trailer shop. i also installed kit #ETBC7 and once agian it was awesome. COMPLETE with DETAILED directions. i'm not a mechanic or hack employee at local trailer shop....BUT dealing with etrailer and there parts made my install very easy and CLEAN!!!

Your products are awesome. Ive had zero issues with it and 5 of my friends purchased and installed the same set up in there trucks. Thanks again for the great products and excellent support.
Matt - 03/05/2015


It was easy for me to hook up to my 2005 gmc yukon xl. plugged in to floor socket. There are videos on youtube for install. I hung under dash to my right. it worked out of the box for a heavy 16 foot trailer. I did by the separate plug/wire connector for my vehicle which made the install easy. Research your vehicle set up for the wiring.


I didn’t have a good location that was reachable while driving so I mounted the controller on top of the dash. I leveled the bracket with a spacer and ran the harness by an access panel. I used about 70’ of the duplex wire due to running the cable to front and then back to the house batteries inside the coach.
The access panel made it easy to make the connections and run the wires through the firewall.
I mounted the 40 AMP and 30 AMP circuit breakers up front in the main fuse panel box. I drilled a hole through the box and firewall to run the wires from the brake controller to the breaker and to the blue wire for the tow connection at the back of the coach.
I ran the battery connections to my house batteries up front instead of using the engine batteries in the back.
I found the brake connection wire under the coach in front directly below the brake pedal.
I mounted the converter in a beam in the back with lots of zip ties

For ford ranger 2010 and perhaps other years:Be aware that the video contains the wrong instruction for the 2010 ranger. In wiring the brake light wire, the switch shown being tapped into gives reverse braking sensing, that is, it is 12 when the brake is not applied, but 0v when it is. I found elsewhere that the correct wire is the 2nd connection on the 5 pin plug that rides on the brake itself.This is no comment on the original video, which was excellent, and referred to the 2011 ranger model.

Used in conjunction with harness kit for my 2002 tundra, this year has no provisions for towing trailer with electric brakes.
The controler itself has proven itself nicely, with no issues with installation or use, adjust easily.
The mounting location I chose may have some slight interference issues with legs on taller people, but I have not had any @ 5'11". The truck is a midsized so room is more limited. I'm towing a tandem 14' trialer with 4 seat RZR, tracking and stopping is perfect, even under hard breaking.


This has been an amazing company to work with. Their chat (a live person!) had the correct list of products I needed for my truck. In less than 2 minutes. Their follow up and dates promised were on target-every time!! I've now used the brakes on 2 trips and they work correctly and are easy to adjust as needed. It has been a pleasure in every way to do business with etrailer!!


Great Brake Controller, used it with the Universal Install Kit for Brake Controllers and No-Drill Mount Bracket, Short - 18140. It only took me 2.5hrs to have it fully installed in my Jeep Wrangler Unlimited 2013. Videos were great. Also having some 1/4in water tubing helped for phishing wire thru frame.
Wish I had watched the video a couple of times before buying and also purchased the extra wire to go from the battery to the brake controller, but had extra wire from another project that worked.
This brake controller works great as we tow a <3500lbs Travel Trailer with our Jeep.
Comes with a great card that helps with settings, keep it in the glove box for future reference.


Great product, very easy install especially with the OEM harness. In about an hour had it installed and trailer set up with controller. Thanks,

Great!! smooth braking when I haul my tractor and other materials
Greg H - 08/30/2019


I recently bought a 2018 Chevy Silverado LTZ. It was equipped with a towing package but no brake controller. Not wanting to alter the interior of the truck too much, I called etrailer for advice. Robert S was very helpful. He suggested the Tekonsha Prodigy P2 brake controller and jumper wire that I was able to hide neatly under the dash using an existing screw. I have been very pleased with etrailer and their suggested product.


Buyer beware! Make sure you check before hand if you can use the included harness or have to use part 7865 that has the diode included due to back feeding power to braking and other ECS functions. Caused errors on my 2017 highlander. Imagine my frustration after finding out this was already a known issue but nowhere did it highlight that as I was placing my order. There’s even a video under the 7865 part number for a 2019 highlander that highlights this problem. I had 2017 highlander as my select vehicle when placing the order too!


Super easy install in my 2009 Touareg. I have the factory tow package and it was plug and play. Towed a camper home 60 miles that night, worked flawlessly.


I purchased this controller for my 2005 Jeep TJ. We're towing a 2014 Forest River FLagstaff MAC and, after doing much research, we decided that this unit (along with the universal installation kit ETBC7) was the right one for us!

Both the controller and install kit contain everything that you'll need for a clean, professional-looking install! The install took around 2 hours (in my driveway) and the controller works flawlessly!

This setup is perfect for a Jeep TJ, the controller fits nicely to the lower left of the steering wheel (out of the way) and the trailer connection is a bolt-on setup that attached to my Reese towing hitch!

The trailer connection (with the install kit) has both a 4-pin connection and a 7-pin connection so there is no need for adapters! It is truly a "plug and play" setup!!

As far as ordering and customer service goes, this was one of the smoothest transactions I've had in quite some time! There are numerous photos and install videos that will guide you through the install.

We'll definitely start with for our next purchase like this!


I installed the brake controller a week or two ago in my 2013 GMC Sierra 1500. I had one just like it in an older Duramax that the previous owner installed--I went with the same product. I had the chance to use it this afternoon to pull a few tons of #57 stone. Trailer plus load I figure about 6000 pounds behind the truck. Pictures are attached.
This is the first 1/2 ton truck I've owned in nearly 10 years and worries how it would do with heavier loads. This controller made a world of difference and really maximized the use of my truck. Great product and I highly recommend it to anyone needing a good controller.


I installed this model 90885 Prodigy P2 Brake Controller using the ETBC7 Brake Controller Wiring Kit on my 2007 Dodge Nitro. On a scale of 1 to 10, I consider myself about an 8 where it comes to automotive mechanical and electrical work. I also strive to get as close to perfection as possible. To do the job right, it did take some time and it did require paying close attention to the directions for both the wiring kit and the controller. However, the directions were "right on", and all the needed "goodies" to do the job were furnished. My hat is off to ETRAILER for the informative videos they provide and their customer service, which includes very quick shipments of their products.

  • Is the Tekonsha Prodigy P2 Needed for a Triple Axle Trailer If I Have a Factory Brake Controller
    I don't have any specifications on the factory integrated brake controller (ITBC) in your 2017 Chevy Silverado 2500/3500 but one would have to think it is capable of handing a triple axle trailer. However, I would play this on the safe side and call your local dealer to confirm. If the factory integrated brake controller is capable of handling a triple axle trailer then you will not need to use the Tekonsha Prodigy P2 Trailer Brake Controller part # 90885.

  • Brakes No Longer Work After Breakaway Pin Pulled
    If I am understanding you correctly, the breakaway pin on your breakaway system was pulled which then activated the brakes on your gooseneck trailer and now the brakes won't work. If that is the case then you may have fried your brake controller as some of the older controllers do not have circuit protection built-in to protect against this.

  • Why Would Prodigy Brake Controller Show Random Numbers Occasionally With No Trailer Connected
    Somehow a 12 volt power source is shorting out to the red wire of the brake controller. This is the circuit that tells the controller to turn on and start looking for braking so an intermittent short here is going to cause the controller to show numbers on the display when you hit a bump. Try checking the wiring of the controller to see if you can separate out the red wire better from the other wires and the problem should go away.

Tekonsha states in the instructions that this can be caused by using testers that are not Tekonsha brands. I have attached a clip from the instructions for you to check out. If you don't have a tester try checking out your 7-Way connector and making sure that all of the pins are in good condition and no corrosion is present....

  • Troubleshooting 2 Flashing Dots and 2 Flashing Bars on Prodigy P2 Brake Controller
    According to the installation instructions when the Prodigy P2 # 90885 has 2 dots it means that it is getting power but no trailer is connected (see attached photo). I am not sure what the 2 flashing bars are though. There are a number of codes that will flash on the display when there is a loss of power or the P2 losses connection but none of them feature 2 bars like you mentioned. If you check out the 2nd picture I attached of the troubleshooting chart this lets you know what the different...

  • Troubleshooting S.H and P.L Codes on Tekonsha Prodigy P2 Brake Controller
    Those definitely look like Prodigy P2 # 90885 troubleshooting codes! You can verify this if the numbers you are seeing are blue. If they are red then this means you have the discontinued Prodigy P1 90185. Regardless of which one you have, the troubleshooting will be the same. The S.H means that it is seeing a short on the brake wire during idle conditions or that non-Tekonsha test lights are being used. The P.L. code means that there is power interruption when you press the brake pedal. Both...

  • Why Did My Trailer Brakes Stop Making a Clicking Sound
    Generally speaking, you should be able to hear a clicking noise which signifies that the magnets are engaging. However, over time as parts begin to break-in, the noise will decrease in decibels but this should not be of a concern unless you lose braking power. I recommend you turn up the brake controller, apply the manual override, and see if it locks up the brakes. If it does then you are good to go but if it does not you may want to check your wiring or test the magnets using the attached...

  • Troubleshooting Tekonsha Prodigy P2 Brake Controller with Intermittent Braking
    The error codes you are getting with your Prodigy P2 Brake Controller # 90885 help explain why you are getting intermittent braking. The "S.H" means you have a short in the brake wire during an idle connection and the "P.L." is a power interruption when you hit the brake pedal. This makes sense in the way you described it as I imagine the S.H. is happening before you move the car and the P.L. is happening when you brake. I imagine there is a short on the blue brake wire somewhere along...

  • What Does C on Display of Prodigy P2 Brake Controller Indicate
    Sounds like your Prodigy P2 part # 90885 is wired up and functioning correctly. C on the display just means that a trailer connection is sensed. What happens when you touch the brakes? The display should jump to the level of braking it's applying to your trailer. If not, you have an issue with the red wire of the controller not being attached to a circuit that sees 12 volts only when the brakes are applied.

  • What Does .C Mean on Display of Prodigy P2 Brake Controller
    The ".c" you are seeing on the display of your P2 part # 90885 indicates that your controller is sensing a trailer connection. As long as you have a trailer connected when you see this it sounds like everything is fine. If you see ".c." instead (note there is a second decimal point), then the controller senses a trailer connection and the boost feature is engaged. The boost feature means the braking power will come on a bit more aggresively.

  • Troubleshooting Continuous Power Being Sent from Tekonsha Prodigy P2 Brake Controller
    Even though the Tekonsha Prodigy P2 # 90885 may not be activated through the foot pedal or override switch it does send a small amount of power back to the 7-Way to check for a trailer connection. If you are seeing a little bit of power on the pin in the 5 o'clock position on your 7-Way then that is normal, but if that is also being displayed on your P2 screen then something internall is going on with your controller and you need to replace it.

  • Trailer Brake Controller that Works on Triple Axle Trailer
    The older Journey brake controller you mentioned can only be used on trailers with one or two axles. So it would not work on a triple axle trailer. The Prodigy P2 part # 90885 that you mentioned does work on triple axle trailers and would be an excellent option that we'd recommend highly. This is our best selling brake controller because of how well it works and how easy it is to setup. This is a proportional brake controller that senses the amount of braking the tow vehicle is applying...

  • P.L. Code on the Tekonsha Prodigy P2 Trailer Brake Controller Part # 90885
    The "P.L." code you are seeing on the Tekonsha Prodigy P2 Trailer Brake Controller part # 90885 means that there is a power interruption while the brake pedal is depressed. From my experience, this means that you have a poor ground on the white wire or short on the black power wire. I would first start with the white ground wire and attach it directly to the negative battery terminal to see if that fixes the issue. If not then you will need to trace the black power wire from the controller...
