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 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 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.


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.

Is this right for you? Product Expert Kathleen M says:

Yes, if you:

  • Tow a trailer or camper several times a year
  • Often use the manual override while towing to feather the brakes
  • Trust a brake controller backed by years of reliable use

No, if you:

  • Have limited leg room in your cab that you can't spare for a bulky brake controller
  • Swap trailers often and want presets so you don't waste time adjusting settings

Installation of Tekonsha Brake Controller Adapter

Brake-Control Adapter Port

This adapter plugs into the 6-pin connector on your vehicle's built-in brake control wiring harness. The harness is located underneath the dash, to the left of the steering column, taped to another harness near the emergency brake pedal.


To install your electric brake controller you need to connect the wiring of the controller to your vehicle. Certain manufacturers offer pre-wired options, typically known as tow packages, wherein these wires are run for you from the dash to the trailer connector on the back of your vehicle. Often, a brake controller wiring harness is included with your tow package. This harness plugs into a port beneath your dash and connects to the four wires of the brake controller. If, however, you have a brake controller with a plug in place of the four loose wires, you can use the Tekonsha adapter.


This adapter requires no hardwiring. It is designed to plug directly into your electric brake controller for the simplest installation possible. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time and securely stow it away.

I purchased the brake controller and wiring harness from you all and installed it watching the video on your website. I followed the instructions to an absolute T. Got everything ready and tested the product and got an SH error code for the blue brake wire shorting out. I pinned and measured resistance and everything was coming back fine (4+ ohms resistance). I then hooked a power prope to it to find the short along the frame and nothing. I had power from the female connector all the way up to the brake controller. After 4 hours of troubleshooting, I found that the female trailer connector was shorted internally. See the attached picture. The blue and green ring terminals inside of the female trailer connector were touching. Replaced the trailer connector and now all is well.

I had a Prodigy P2 controller in my last pickup and was really pleased with it. So wanted to install the same thing in my newer truck Everything worked smoothly on installation. Made the necessary adjustments to controls after hooking to the trailer and it works great!



by: Duane03/14/2024

I have a Tekonsha controller on my 2001 Chevy Silverado and it worked like a charm for over 18 years.I'm sure that the new Prodigy P2 will do the same.



by: Carl05/15/2023

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.



by: Philip03/04/2016

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.

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!

2017 Chevrolet Traverse

I am a retired auto mechanic so I truly know and appreciate when something is actually plug and play. Our 2017 Chevrolet Traverse had the factory V92 trailer towing package listed on the build sheet so the plug for the trailer brake was where it was supposed to be. The controller is easy to adjust and has an LED display to let you know if it senses a connection. Additionally, there are three levels of brake application based on trailer weight. We tow three different trailers so this feature is appreciated. Completely works as advertised and all for a good price.



by: Larry L.04/29/2015

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



by: Calvin03/14/2024

Great product! Since I pull my goose neck with electric brakes, with my semi truck tractor, it acts as a interface between the air brakes and the electric trailer brakes, and acts as a Johnson bar if I need to get the trailer back under control.



by: Matt02/24/2014

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!!!



by: David03/03/2024

The Tekonsha Prodigy P2 Brake Controller arrived on time and is just what I needed. The installation and operating instructions are easy to understand and should make installation a breeze. I'll give an update after I get it installed.



by: Kevin P.03/16/2011

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



by: Joseph05/24/2022

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.



by: Daniel 01/05/2023

The plug matched the truck's wiring harness and works good. The instructions were very clear and easy to use.

This connector worked well, installed easily



by: Dale 01/14/2024

My 2002 Tundra was not manufactured with the modular plug for trailer brakes. While searching for the solution, the Tekonsha Prodigy P2 showed up with a complete installation video from front to back (battery to hitch).
Now installed, it performs great with my trailer rig.



by: Garry in Indio06/25/2017

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.



by: Dan 06/05/2023

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.



by: Clayton 02/12/2024

Very easy to install with the help of a video that shows how to to find the wiring. I could not find the wiring in the cab until finding the video online and because of that help I ordered the brake controller.



by: Anthony 03/25/2024

I just received item in the mail, have not installed it yet, but the fact that the website had a installation video for my specific vehicle was the reason I chose to purchase this brake controller.



by: Nick04/11/2016

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.



by: David W02/16/2019

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.



by: Earl05/15/2022

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



by: Ken05/27/2023

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.



by: Greg08/30/2018

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



by: Thomas08/19/2021

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

  • Troubleshooting Prodigy P2 Brake Controller Only Activating Brakes with Manual Override
  • The first thing you will want to check is simply how you're actually testing the Tekonsha Prodigy P2 Brake Controller # 90885 on your Silverado with the trailer hooked up. This is a proportional controller, meaning it will send back an amount of power to the trailer brakes proportionate to the rate of deceleration on the vehicle. If you are testing the unit with the truck and trailer parked, it's going to send back very minimal (if any) power back to the brakes when stepping on the brake

  • Troubleshooting Nissan 7-Way Wiring Where Brakes are Locked Up When Trailer is Connected
  • The issue is that the electric brake signal wire and the 12V battery charge wire are reversed in the main vehicle harness. This is the reason that the trailer wiring harness you have has a constant 12V signal on the brake controller output circuit. Since there is constant power to the brake controller output in, there should be no signal on the 12V battery charge pin. The easiest solution is to cut the wires leading to the output pin and the 12 volt pin on the 7-way and reconnect them backwards.

  • Tekonsha Prodigy Trailer Brake Controller Flashing S.H. then O.L. Towing Utility Trailer with Dump
  • When looking at the instruction manual for the Tekonsha Prodigy P2 Trailer Brake Controller # 90885, it looks like the "S.H." you referenced will flash when the brake wire sees a short during idle condition. The "O.L" flashes when the Prodigy P2 "sees" an overload condition during operation. I am not sure why those error message are coming up on the brake controller since you do not have electric brakes installed on your trailer, unless the wiring for the dump mechanism is somehow tied

  • Finding Brake Switch Wire to Install Brake Controller on a 1989 Chevy K2500 Pickup
  • The white brake switch wire was the common brake light only wire on 1992 and newer Chevy trucks and SUVs but not on the 1989 C/K series trucks. I am not certain which brake switch wire you will need so the only way to know is to test the brake switch wires using a circuit tester such as # PTW2993. The truck key may or may not have to be in the on position. You are looking for the wire that only has power when the brake pedal is pressed. If the wire also has power with the headlights

  • Ground Error and Weak Trailer Brakes Using P2 Brake controller on a 2004 Ford F-250
  • The P2 brake controller # 90885 will initially hold the trailer brakes when stopped at a traffic signal but will then start to release them. That is normal for that particular controller and many proportional controllers because they have to sense movement to send power back to the brakes. There could be a weak ground and attaching the ground wire to the battery is the best ground location there is for a brake controller. Using 12 gauge wire will be fine for the brake controller ground

  • Wiring Harness to Install a p2 Trailer Brake Controller on a 2002 GMC Yukon Denali
