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 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.

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!

It is working great!! Wouldn’t be without it!



by:

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:

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?

Carl B.

6/22/2023

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.



by:

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.

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.

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!



by:

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:

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.



by:

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:

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.

Patrick B.

8/19/2013

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.


by:

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



by:

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:

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:

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:

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:

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:

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:

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:

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

Earl

No problems at all with this unit. Dependable and smooth braking while pulling fully loaded trailer.



by:

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:

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

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.



by:

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!

  • Brake Controller Constantly Drawing Power From Battery
    The Prodigy P2 # 90885 like all other electric brake controllers will have a very small constant draw from your battery. This is not something to be alarmed about as it is part of the design. It's purpose is to allow the connection to remain so you don't need to reboot each time you start and stop your vehicle. It is such a small draw that you don't need to be concerned about it draining your battery unless you are leaving the vehicle for multiple months in storage. If that is the case,...

  • Should the Center Blue Dot On a Tekonsha Prodigy P2 Be On When Vehicle Is Turned Off?
    Depending on how your vehicle is wired for a trailer brake controller will determine if the center light on your Tekonsha Prodigy P2 Trailer Brake Controller # 90885 will stay on. Some vehicles will always provide power to the controller as it is fused straight from the vehicle battery. Others will use a relay which will only allow power to reach the controller when it senses the ignition is switched on.

  • What Circuits Should a Prodigy Brake Controller Run to
    If I had to guess the guy installed the brake controller wrong and never tested it with a trailer. You need to move the wiring of the controller around so that all of the circuits are run to the correct wire. The blue wire is right, the white is for ground, the red for stoplight switch, and black for 12 volt power. Just like in the chart I attached.

  • Recommended Brake Controller and Install Procedure for 2013 Chevy Suburban
    I'd recommend you use a proportional controller. A proportional controller features an integrated accelerometer so the controller can determine how quickly the tow vehicle is braking. It will then send the appropriate amount of voltage to the trailer brakes so that the trailer and tow vehicle stop at the same rate. This provides safer, more predictable braking, and can mean less wear and tear on the vehicle and trailer brakes because neither vehicle's having to do all the work. I really...

  • Troubleshooting Brake Controller that Only Works with Override Lever 2008 GMC Sierra
    Since the CHMSL fuse was initially blown I would recommend first checking it again to see if it has blown again. I am thinking there is a short on this circuit that immediately is blowing the fuse everytime the brakes are applied. You can run out and check to see if the third brake light on your truck is still functioning. If not, then the fuse has blown again. Chevy fuses do seem to blow more frequently than other truck manufacturers so I suspect that is the problem. I would also check...

  • What Speed is Best for Making Brake Controller Adjustments
    You can make adjustments to a brake controller at any speed but the recommended time to setup a brake controller is at lower parking lot speeds to be on the safe side. Drive forward at about 25 mph with enough distance for safe braking, apply the trailer's brakes using the manual control lever only. The output should be set to a point where brakes do not lockup, but stops are firm and smooth. If needed, adjust the output setting up or down, then retry. Using the brake pedal, make additional...

  • Can Power Switch Be Added to Brake Controller
    Because of the danger that the user could forget to turn it back on before towing, brake controllers are installed to a constant 12V feed. After 15-20 minutes or so of inactivity, the controllers goes into a sleep mode during which time the controller only draws enough power to keep one LED dot lit, which is a miniscule amount. You'd need to leave the vehicle unattended for 2-3 months or more before you'd need to worry about discharging your battery. Because of that, I wouldn't recommend...

  • How Does Brake Controller Install in 2008 Chevy Suburban
    On your 2008 Chevy Suburban there is a set of wires under the dash that are used for hardwiring a brake controller to. If you check out the help article I attached you will see exactly how to find and use this harness. I also attached an install video that will walk you through the process as well. For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup. This...

  • P2 Trailer Brake Controller Shows 2 Dots that Never Go Away with Key Off and Removed
    I spoke with my contact at Tekonsha and he stated that when the 2 blue dots occur and will not shut off you will need to reset the controller. What you will do is unplug the harness from the back of the controller and let it sit of at least 30 seconds and then plug it back in. When it is plugged back in it should flash NC for several seconds and then go back to the dots. After about 30 minutes the controller should power down and the dots should go away. If they do not then the controller...

  • Troubleshooting Prodigy Brake Controller that Outputs Only 2.7 Volts When Pedal is Pressed
    Your Prodigy brake controller is a proportional type that uses an internal accelerometer to determine how much braking power to deliver to the trailer brakes. When you press the manual override you are bypassing it; it will deliver full power. But when you press the brake pedal you are telling the controller to send out a matching brake signal equal to your rate of deceleration. If the vehicle is not moving there will be nothing to tell the unit how much braking power to output and so it...

  • Troubleshooting Intermittent Trailer Connection Message on Dash of Truck
    This is a pretty common issue and the solution is typically to just a matter of cleaning off the pins of the trailer wiring connectors as corrosion has accumulated to the point that the trailer wiring connection is intermittent. Take some sandpaper to the pins and you should see the problem go away.

  • Installed Brake Controller is Causing 2010 GMC Yukon XL to Lose Power
    On your 2010 GMC Yukon there are tow package wires located under the dash to the left of the steering column and held together with a white tag. If those are the wires your husband used then they are the correct ones. But sometimes it is possible to accidently connect a brake controller wire to the wrong tow package wire. On your Yukon the red/black tow package wire goes to the controller black wire for 12 volt power. The white wire goes to the controller white wire for ground. The Yukon...

  • Tekonsha Prodigy P2 Trailer Brake Controller Brake Signal Source
    It is best to avoid tapping into your wiring converter for your brake controller's input signal. The Prodigy P2 # 90885 is designed for the voltages found at the brake light switch, which could differ from what is found at the taillight converter. If you do not want to do the standard hardwire installation then the better alternative is to tap into the brake light signal at the CHMSL (center high-mount stop light, or 3rd brake light). This will also require running a length of additional...

  • Why Would Tekonsha P2 Brake Controller Show Intermittent NC and C on Display While Travelling
    An intermittent connection on the brake output circuit of your vehicle/trailer is causing the NC to flash occasionally. Nearly every time we see this the problem is dirt or corrosion built up on the trailer or vehicle connector. Cleaning this with some fine grit sandpaper will most likely do the trick. I attached a help article on troubleshooting brake controller installs for you to check out as well.
