Proportional Braking

With a proportional brake controller, you can get heavy-duty emergency braking, general braking or slow-to-an-idle braking for your trailer automatically. The intensity with which your trailer brakes are activated and the rate at which they are applied are dependent on the deceleration of your tow vehicle. This means that, unlike time-delay controllers - which send the same amount of preset power to your trailer brakes every time - proportional controllers are able to adapt to every braking situation differently. So, if you slam on the brakes in your truck, your trailer brakes will activate with that same extreme intensity. And if you merely slow down as you approach a red light, your trailer will gradually brake in the same manner. Just set the initial power level, select a boost setting, and you're good to go.


As long as the P2 controller sits level on a horizontal plane and is pointed in the direction of travel, it will sense - via an internal inertia sensor - how your tow vehicle brakes. This inertia-based sensor responds to the deceleration of your tow vehicle as you brake by signaling the controller to send out enough power to your trailer brakes so that they are activated with an intensity that matches. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.


Power Boost for Heavy-Duty Towing

Aside from smoother, more efficient braking, Tekonsha's P2 brake controller also offers a boost feature that gives you more initial braking power for those times when you're towing heavy loads. You can switch boost levels so that the power output to your trailer brakes automatically starts out at either 14 percent or 28 percent of the predetermined power setting.


So, if you boost the initial power so that your trailer brakes activate with 28 percent of the overall intensity at the start, the brakes will reach maximum braking faster. This is particularly beneficial if you are towing a heavy load because the intensity required to stop that load may be far greater than that needed to halt your vehicle. Therefore, sending out more initial power to the trailer brakes - and causing them to reach maximum braking faster - allows you to better control the trailer so that it doesn't push your tow vehicle before coming to a complete stop.


If your trailer weighs less than your tow vehicle, no boost is needed. But if you wish to set the boost so that your trailer leads the braking of your towing setup, you can select level B1. The following table gives an indication of when you might use the different boost levels and the power increases that they offer.


Approximate Gross Trailer WeightBoost LevelIncrease in Initial Power Output
Less than tow vehicle GVWB114%
Equal to tow vehicle GVWB1 or B214% or 28%
Up to 25% more than tow vehicle GVWB2 or B3*28%
Up to 40% more than tow vehicle GVWB3*28%

*Both B2 and B3 offer a 28-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 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 P2 is not in use, it will be in power-saving mode. In this setting, the power draw falls to only 3.6 milliamps, minimizing drain on your vehicle's battery.


When you stop at red lights, or any time that your truck and trailer are at a standstill with the brakes applied for more than 5 seconds, the P2's "hold" feature will activate. When this happens, the power output to your trailer's brakes will be reduced to just 25 percent of the preset power setting so that the brakes will not overheat.


If ever there is a time that you need to brake your trailer separately from your tow vehicle - when traveling down a steep incline, for example - the manual override lever is easily accessible. Pushing this lever engages the brakes on your trailer with full power. In addition, when you activate this override, the brake lights on your trailer will illuminate, properly warning those behind you of the braking action of your rig.


In addition to all of those safety features listed above, the P2 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.


Correct P2 mounting360-Degree P2 mounting

Note: The P2 must be mounted on a level horizontal (side-to-side) plane and must be lined up with the direction of travel for the internal sensor to function properly.


Installation is a snap. After mounting the P2 unit in your cab using the included pocket mount, hardwire one end of the included pigtail harness directly into your vehicle. The other end plugs into the brake controller. To transfer the P2 to another vehicle or to remove it for storage, just unplug the unit and slide it out of the pocket mount.


Installation Accessories

For even easier installation, a vehicle-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.


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


See also etrailer.com'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.

After hearing horror stories at dealer, had controller installed on new Jeep gladiator (trailer dealer said good choice of controller). Towed 16' airstream to SW FL from NV thru CA in Fed/Mar of this year. Total of 8,000 miles. Absolutely needed the controller in Utah mountains driving down to Vegas. Stupidly jerked steering wheel going downhill but controller worked perfectly and keep me on the road. Scary but learned a lesson. So glad bought from etrailer.com. 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!

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.

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

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!!!

Haven't connected it to the camper yet but the logic and display is the same as the 10 Y/O Tekonsha controller in the previous tow vehicle. The controller looks like it was made for the Ukraine army to use as it appears bulletproof.

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


Comments
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.
-- comment by: Scott M - 08/15/2013

Wire colors can and do change often. We offer the colors that we find in our videos as a starting point, but even if you have a 2011, it is best to double check and make sure to positively identify the wire color first.

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.

Unfortunately you use USPS for shipping. Totally unreliable. No tracking showed up until Sunday. Up until then it showed they were waiting for the merchandise from you. So, I figured it was lost and since I needed it I ordered another controller from Amazon and it arrived on Saturday. If you consider giving the purchaser (me) the option of shipping with UPS, I will consider future purchases.

This controller was for our Escape19 trailer. So far this year we've traveled 10,000 miles circling the US. Since this is our first trailer, I haven't tried any other controllers but this one worked great. When we bought this in Sept 2020, we were lucky to get one because of the supply chain problems. I recently had the trailer and vehicle serviced and the results say that this was a good product.

Love dealing with these guys. So helpful, they know their stuff. We needed the connector and a brake controller for a 2018 motorhome. Their web site they had a video of where to find the connection site in the RV and they had the right parts at a great price. They also had the all the little odds and ends (windshield cover, sink stopper, new bath faucet, led light, etc.,) that we needed. The parts were delivered within a week.

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.

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.

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 etrailer.com for our next purchase like this!

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.

I have been very pleased with etrailer and their suggested product.

If this method does not clean the contacts and take care of the problem then something is wrong with the internal circuitry of the brake controller and the brake controller will have to be replaced.

  • What Does the SH Error Code and a Single Dot Mean on the Prodigy Break Controller, # 90885
    The SH code on the Prodigy Brake Controller, # 90885, indicates that while idle, the brake controller is sensing a short in the brake wire. Tekonsha states that some test lights or non-Tekonsha testers can cause this problem. The NC code means no trailer is connected. The cause to both of these error messages may be solved by cleaning both the vehicle side and trailer side connectors of any dirt or corrosion. Also make sure the brake wire from the controller to the 7-Way is not broken or...

  • Troubleshooting P-2 Brake Controller Installation on a 2008 Chevy 1500
    Since there is no power at the bundled wires under the dash the problem is most likely under the hood at the power distribution box. The power for the brake controller is supplied from a wire that is located between the driver-side front fender and the power distribution box (see photo link). There is a ring terminal on the end of the wire and it should be ran to the left power stud located at the front of the power distribution box with a M6 nut, item # 185916. If the wire is connected...

  • Brake Controller Recommendation for a 2010 Chevy Avalanche Towing a 5000 lb Dump Trailer
    Brake controllers are not vehicle or trailer specific, so most controllers would work fine for your application. This being said, the Tekonsha P2 you were looking at would be a good choice for your current set-up. The P2 is a proportional-type controller that works to ensure both tow vehicle and trailer brake at the same rate, which makes for safer and more effective braking. The P2 features 3 different boost settings for more aggressive braking when towing heavier trailers. The P2 will...

  • Troubleshooting Prodigy P-2 Brake Controller 90185 When the Unit Displays an S.h Error Code
    The S.h error code is indicating that you have a short on the brake wire, normally during an idle condition. I would recommend checking along the electric brake wires on both your vehicle and trailer to make sure there are no pinched or exposed points that may be touching metal. If you are looking at the front of your vehicle connector, the electric brake wire would be run to bottom right pin if you have a 7-Way plug. The electric brake pin on a 6-Way plug would be in the second position...

  • How to Wire a 2007 Toyota FJ Cruiser for a 90885 Prodigy P2 Electric Brake Controller
    The Toyota stoplight wire color is normally green with a white tracer, but you would need to test to confirm whether this is correct for your 2007 FJ Cruiser. Locate your stoplight switch and use a circuit tester on the wires that come out of it. The wire you are looking for will get power when the brake pedal is pressed, but will not have a power reading when the pedal is released. Connect the red wire from the P2 brake controller to this wire. You can view some additional information...

  • How To Wire Brake Controller Into Stop Light Circuit of 2006 Chevrolet Uplander
    I contacted our representative at Tekonsha and he informed me that they have just released a tech bulletin on wiring a brake controller on the Chevrolet Uplander. He informed me that you cannot run the stoplight wire directly to the brake light switch. You will need to locate the Body Control Module (BCM) which is located under on the left side of the dash on the drivers side. It will be located above your left knee if you were seated in the driver seat. You will need to locate the white...

  • What Differences Will Arise When Switching from an Orignal Prodigy to a P2 Brake Controller 90885
    The P2 brake controller # 90885 would offer a few upgrades in comparison with your original Prodigy brake controller. The most noticeable feature in your day to day use would probably be that the P2 has a 360 degree mounting range, as compared to the 70 degree range on the Prodigy. Looking to your future towing needs, the P2 is also compatible with electric over hydraulic brake systems, while the Prodigy only works with trailers with electric brakes. Both units would use the same plug,...

  • Mounting a Tekonsha Primus in a 2011 Toyota Tacoma
    I have examined interior photos of the 2011 Tacoma, and it appears that the Primus could be mounted either just to the left or right underneath the steering column, to the plastic under dash trim. The Primus can be mounted in an orientation up to 70 degrees nose up, so even though that lower dash portion is not flat, the controller should mount to that area with no problem. You will want to be sure that the controller is installed so that it is parallel to the direction of travel. For...
