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'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.

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!
Thomas - 08/19/2022


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:


This controller is great and it was straight forward to install. I have a 2001 F-350 and the hardest part was finding the factory plug that's supposed to be there if your truck has a receiver hitch,ie. Tow package. It's up under,and along side where the ash tray in the center of the dash would be if you don't have a pocket there instead. It's near the top of where the ash tray is, and has a plastic pin holding it to the metal bracket and is covered in tape. It's hard to tell that it's a stray plug unless you see it after removing the whole dash and instrument panel... however it would be easily found if you knew where to feel for it, and no dash disassembly was necessary after all! Reach up under the dash from the drivers side near the middle but offcenter towards the drivers side. Find the flat metal supports for that area not too far up, and feel for a secured lump stuck to one side of a bracket and pull it off if it has wires going to it and none coming out of it.

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.

Install was a breeze and I am looking forward to doing business with e-trailer again soon. Installed on a 2010 Cadillac Escalade. Going to be pull a C-24 Cutwater with electric over hydraulic brakes.


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!

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


very easy installation and it worked like a champ on a 1200 mile round trip with a GMC 1500 pulling a 7K trailer. Would 100% recommend this Controller for a late model Chevy/GMC 1500 with a bumper pull RV.


Works perfect. Great product. Get the wiring harness with it. Two minute installation.


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.

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 Thank you.

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.

I will have our customer service team reach out to you.

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.


Janet was very helpful in answering my questions and helping me select the correct trailer brake controler for my 2007 Nissan Frontier. Didn't need to cut and crimp wires, it was all plug and play. I needed it ASAP and got it in two days. It's good to have customer service in the U.S. and not have to struggle with foreign accents. Thanks 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.


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.


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

This brake controller is a life saver. Easy to install and easy to use. Didn’t require instructions to install as its self explanatory. The actual brake control unit is intuitive and simple.


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.


Quick delivery and installation with easy to follow instructions. The service manager at the RV shop said it is the same unit he has in his personal vehicle.


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!


A little work removing the truck trim,but the install went well. Just plugged it in and put back together. Looks like a pro install


Working well after one year’s use. Watching the etrailer install video for my car model was very worthwhile. If you’re not comfortable with basic automotive electrical stuff I would enlist a friend to be on standby who is!

  • How Does Brake Controller Install in 2012 Chevy Colorado with Factory 7-Way
    All you need to install the Prodigy P2 brake controller part # 90885 is the controller itself for your 2012 Chevy Colorado since your truck has the factory 7-way. There's a bundle of wires under the dash of the truck that this controller wires to. If you check out the install video I attached you can see exactly how this controller installs on a Colorado similar to yours.

  • Location of Brake Controller Wiring for 2012 Chevy Colorado
    The wiring to install a brake controller like the Prodigy P2 # 90885 on your 2012 Chevy Colorado is likely to be just under the emergency brake pedal, near the door jamb, like you see in the accompanying photo. This photo is from an installation on a 2015 Colorado, but the wiring should be in the same location. I have added a link to the install video for you to check out, as well as a link to a number of help articles on brake controller wiring I recommend taking a look at.

  • Brake Controller Overload Error Message
    There are several things that can cause an overload error on a brake controller like Tekonsha Prodigy P2 Trailer Brake Controller # 90885 you referenced. Typically an overload error is caused by a short on the brake output circuit. The first thing I would do is disconnect the trailer from your tow vehicle and inspect both connectors for damaged terminals or corrosion build up. Bent or corroded terminals can cause one circuit to cross over and short another out. You'll also want to visually...

  • Troubleshooting PL Error Code of Tekonsha Prodigy P2 Brake Controller
    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 our experiences this means that you have a poor ground on the white wire or short on the black power wire. This could have easily happened with the work you had done. 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...

  • Troubleshooting Prodigy P2 Brake Controller that Has PL Error Code
    What brand of EOH actuator is on the trailer? You might try running a jumper wire from the positive battery post to the black wire of the controller to see if that prevents the issue as well. Typically this error is caused by power interruption on the power wire so running a jumper wire would allow us to know for sure if the wiring is at fault or if it's something else.

    If you have a proportional brake controller like the Tekonsha Prodigy P2 Trailer Brake Controller part # 90885 then this is normal. The reason for this is because a proportional brake controller is not going to send very much power to the trailer brakes while at a dead stop because there is no inertia for the controller to sense. However, if you are getting no power at all at the trailer connector while using a multi-meter then there might be an issue with the stop light switch connection....

  • Troubleshooting Tekonsha Prodigy P2 Brake Controller Staying Lit and Numbers Flashing
    It does sound like your Tekonsha Prodigy P2 Brake Controller # 90885 is just in need of a manual reset. The only way to really do this though is to unplug it from power by removing the plug at the back of the controller itself or unplugging from a factory port behind the truck's dash (if it was equipped with one). If you truly aren't able to access the plug then your only option will be to sever the black 12V wire from the back of the controller to cut off power. Once you are able to...

  • Can Factory Brake Controller of 2009 GMC Sierra be Bypassed with Prodigy P2
    You can bypass the factory brake controller of your 2009 GMC Sierra but there isn't an install harness for your vehicle that will be used. Instead you'll have to make some connections from the wires of the P2 part # 90885 to the wiring harness under the dash of your truck. There is also a few connections under the hood that need to be made but you don't have to make a trip to a dealer to have any error codes addressed. I attached a link to this page that will walk you through the entire...

  • Will the Inertia Sensor On a Trailer Brake Controller Apply Brakes Without Pressing the Pedal
    The Tekonsha Prodigy P2 Trailer Brake Controller part # 90885 does indeed have an internal inertia sensor that senses deceleration and applys voltage to the trailer's brakes accordingly however, this inertia sensor must first become triggered from the brake pedal. Therefore, your trailer's brakes would not activate without the red wire attached and the brake pedal depressed. Unfortunately, I don't have any wiring schematics for a Chevrolet Blazer but all you will need to do to find the...

  • Which Wire From Trailer Brake Assembly Does Brake Output Wire Connect To
    The blue wire from your brake controller like the Tekonsha Prodigy P2 # 90885 you were looking at is what carries power back to the electric brake assemblies on the trailer. Each individual brake assembly on the trailer will have two wires coming out of it - one for power (which gets hooked up to this blue brake output wire) and one for ground (which gets attached to a clean portion of the frame). The two wires on the assembly have no polarity, so it doesn't matter which wire you use for...

  • Troubleshooting Tekonsha Prodigy P2 Brake Controller Sometimes Not Releasing Brakes
    The issue you're describing could be coming from a few possible areas, including the brake controller itself. Since the trailer brakes are sticking with multiple trailers, we at least know the issue is somewhere on the truck side. What I first recommend doing is making sure the red wire from the Tekonsha Prodigy P2 # 90885 is still securely connected to the brake switch wire on the truck, or if you used a Plug-In Adapter Harness for installation, that the plugs are fully seated with each...
