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.

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!


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


This 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.


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

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 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 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!

The tow package wiring will have a white tag wrapped around it, and will consist of a Red, Dark Blue, Light Blue or Orange, and a White wire. The plug included with the controller will...

  • Troubleshooting New Trailer Brakes That Seem Weak
    Since you said the trailer is brand new that leads me to believe that your brake assemblies are self-adjusting assemblies that just haven't been activated enough times for them to find the right setting and work properly. What you will want to do is keep repeating the testing process you have done until you feel the brakes start grabbing hard enough to lock the brakes up. They should progressively get strong and stronger with each application of the manual override lever. Or, if the brake...

  • What Is Needed To Convert Surge Brakes To Electric Over Hydraulic On Tri-Axle Boat Trailer
    The first thing you will want to do is make sure that the brake controller you have installed is compatible with electric-over-hydraulic brakes you plan on converting to on your tri-axle boat trailer. Many of the factory-installed brake controllers are for electric brakes only and would need to be replaced to be able to work with an EOH system. I have attached a helpful article that explains what is needed to convert your system to an electric-over-hydraulic system. If you want to let...

  • Best Brake Controller Recommendation for a 2008 Chevy Silverado 1500 Towing a Horse Trailer
    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.

  • Wiring a Trailer Brake Controller to a 2013 Coachman RV Using Ford Wiring Harness

  • When to Use Reverse Mode Feature of Prodigy P2 Brake Controller
    If you're in a situation where the maneuvering is going to take you more than two or three minutes, you'll want to put the controller in reverse mode. This will cancel the boost level if you have it set and cancel the hold feature. If you're backing for a very short duration, you don't need to switch to the reverse mode.

  • Does a 2012 GMC Canyon have Tow Package Wiring for a Brake Controller
    Yes, there are wires under the dash of your 2012 GMC Canyon to wire in a brake controller. There will be a wire bundle under the dash, to the left of the steering column, held together with a white tag. That tag should list the functions of each of the wires. On the brake controller # 90885 the white wire is ground, the black wire is 12 volt power into the controller, the red wire is input from the brake switch, and the blue wire is output to the trailer brakes.

  • 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...

  • Is there a Wiring Harness to Install a Brake Controller on a 2002 Bounder on Freightliner Chassis
    We do not have a wiring diagram for the motor home and Freightliner chassis. It will be a hardwire type of installation since there isn't a harness specific to your motor home. On the P2 brake controller # 90885, the white wire is ground, black is 12 volt power in, red is input from the brake switch, and blue is output to the trailer brakes. The motor home manufacturer may have a diagram that you could use. If you are unable to obtain a diagram I have included some links that explain...

  • Recommendation for Finding Brake Light Circuit for Installing Brake Controller in 1998 Chevy Truck
    That would be a great idea. The CHMSL or center high mount signal lamp circuit would be a great way to get the brake light circuit to install your brake controller like the part # 90885 as it only carries the brake light's signal without any turn signals. You may be able to find the circuit near the fuse box or at the third brake light. I attached an FAQ on wiring up a brake controller from scratch for you to check out as well as a video that shows a 1997 Chevy truck brake controller install.
