Proportional Braking

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


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


Power Boost for Heavy-Duty Towing

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


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


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


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

*Both B2 and B3 offer a 28-percent boost in initial power. But the braking curve for B3 is more aggressive than that of B2. This means that, even though you will start out with the same intensity when using these boost levels, you will get an overall more aggressive braking experience with the higher level. So if you use B3, you will reach maximum braking sooner than if you use B2.


Safety Features

The Prodigy P2 offers advanced safety features to prevent damage to various components of your towing setup. Integrated reverse battery protection shields the brake controller and your trailer's breakaway system from shorts. When the P2 is not in use, it will be in power-saving mode. In this setting, the power draw falls to only 3.6 milliamps, minimizing drain on your vehicle's battery.


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


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


In addition to all of those safety features listed above, the P2 offers diagnostics such as:

  • Open ground
  • Overload
  • Output short
  • Power loss
  • No trailer connection

Automatic Leveling and Simple Installation

The self-leveling feature of the P2 ensures that the brake controller continues to function even as you drive up steep hills or through the mountains. Simply mount it in your cab at any vertical angle, and the controller will level itself automatically thanks to its 360-degree rotational range.


Correct P2 mounting360-Degree P2 mounting

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


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


Installation Accessories

For even easier installation, a vehicle-specific wiring adapter (sold separately) is available for most newer trucks and SUVs. One end of the custom adapter plugs into your vehicle, and the other end plugs into the controller - no hardwiring required.


Note: If a custom brake-control wiring adapter is not available for your vehicle, one of the following will be required:

20-Amp circuit breaker (9506P - sold separately) for 2- to 4-brake applications

30-Amp circuit breaker (38630 - sold separately) for 6- to 8-brake applications


See also etrailer.com's exclusive 7- and 4-way brake-control installation kit (ETBC7 - sold separately) if you don't already have a 7-way plug at the back of your vehicle.

Still works after a year! It really has done a great job! Thank you!

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: https://www.etrailer.com/faq-etbc7.aspx

Everything works great! Despite Camping Worlds inability to install lights and e-brake, I did it myself.

Very well, easy enough to install when Camping World was unable to install

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.




by:

The Prodigy P2 controller mounted securely in the cubby hole of my 2009 F150 where the factory controller would have been. It sticks out a little, but needs to for access to the manual control on bottom. It was plug and play with the truck's wiring harness. (Truck has the tow/haul option.) Seems to be a great solution.

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.

The online video showing the installation of the Prodigy P2 trailer brake control into a 2011 Ford Ranger was excellent! It made the installation into my Ranger simple and straight forth.
I have yet to hook up to my travel Trailer and adjust it for brake setting, but all readout displays thus far are as stated in the instructions.
Having previously installed the trailer connector, I did not purchase the installation kit and in retrospect for cost effective and simplicity would recommend anyone to purchase the kit along with the controller.
I believe I am going to be very pleased with this product.
Thank you

very nice controller, very smooth and you don't have to mount it flat!! e trailer is the best company i ever worked with. they have pics, video, email support(exellent) and just flat out make it easy for you to do it yourself instead of paying some dirt bag $300 to install at your local trailer shop. i also installed kit #ETBC7 and once agian it was awesome. COMPLETE with DETAILED directions. i'm not a mechanic or hack employee at local trailer shop....BUT dealing with etrailer and there parts made my install very easy and CLEAN!!!

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.

I didn’t have a good location that was reachable while driving so I mounted the controller on top of the dash. I leveled the bracket with a spacer and ran the harness by an access panel. I used about 70’ of the duplex wire due to running the cable to front and then back to the house batteries inside the coach.
The access panel made it easy to make the connections and run the wires through the firewall.
I mounted the 40 AMP and 30 AMP circuit breakers up front in the main fuse panel box. I drilled a hole through the box and firewall to run the wires from the brake controller to the breaker and to the blue wire for the tow connection at the back of the coach.
I ran the battery connections to my house batteries up front instead of using the engine batteries in the back.
I found the brake connection wire under the coach in front directly below the brake pedal.
I mounted the converter in a beam in the back with lots of zip ties


Comments
For ford ranger 2010 and perhaps other years:Be aware that the video contains the wrong instruction for the 2010 ranger. In wiring the brake light wire, the switch shown being tapped into gives reverse braking sensing, that is, it is 12 when the brake is not applied, but 0v when it is. I found elsewhere that the correct wire is the 2nd connection on the 5 pin plug that rides on the brake itself.This is no comment on the original video, which was excellent, and referred to the 2011 ranger model.

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.

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.




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:

Works well.

Only thing, we had
to move it down from the initial instal because I couldn’t get the column shifter down into low. Rookie mistake.
I like the manual advance bar on bottom. Easy to find & use without looking down.
I like that the display shows when it is hooked to trailer.
Easy enough to set up & change for differing loads.

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

With the proper adaptor for your vehicle, this is a very simple and fast install. Hardest part is trying to find the best location to put the controller that is best for 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 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!

I installed the brake controller a week or two ago in my 2013 GMC Sierra 1500. I had one just like it in an older Duramax that the previous owner installed--I went with the same product. I had the chance to use it this afternoon to pull a few tons of #57 stone. Trailer plus load I figure about 6000 pounds behind the truck. Pictures are attached.
This is the first 1/2 ton truck I've owned in nearly 10 years and worries how it would do with heavier loads. This controller made a world of difference and really maximized the use of my truck. Great product and I highly recommend it to anyone needing a good controller.

    If you are only getting input to the controller on that red wire when the brakes are pressed, but you are getting constant output on the blue output wire, your controller is bad and must be replaced. I'd recommend a proportional Brake Controller, such as the Tekonsha Prodigy P2, part number 90885. A time delayed controller will send the preset amount of voltage to the trailer brakes every time the brake is pressed, whether it is a panic stop, or a quick jab to the brake pedal. A proportional...

  • Is a Brake Controller Necessary for Trailers with Electric Trailer Brakes
    If your trailer has electric brakes and you want them to properly actuate, you will need a brake controller. The brake controller is tied into the circuit for the brake stoplight switch, which tells the trailer brakes when, and with how much force to actuate. I would recommend a proportional controller. A proportional brake controller has an internal sensor that can tell how quickly the tow vehicle is stopping, and will send the appropriate amount of braking force so that the trailer...

  • Best Brake Controller for Truck with Air Brakes
    Since the brake controller is activated by picking up the brake light signal, any controller would work fine for your trailer. Since jake brakes typically do not activate the brake lights, you would be fine using the jake going downhill without actuating the trailer brakes. The Tekonsha Prodigy P2, part # 90885 would be a great choice. It is very easy to use and setup.

  • Brake Controller Troubleshoot on 2005 Ford F150
    There is not a rheostat in the controller, but there is an inertial sensor that senses how quickly the vehicle stops, and then sends the appropriate voltage to the trailer brakes. The variable voltage you read when using the manual override will depend on how high the output on the controller is adjusted. The small amount of voltage you get when the brake is pressed is actually the voltage the controller sends to verify that the trailer is connected. The controller will not send full voltage...

  • Prodigy Brake Controller Is Disconnected but Display Indicates Connected
    I spoke with our technical advisor and he said to start with the 7-way plug on the back of your Silverado. Unplug the 7-way plug from the factory plug beneath your rear bumper. If your Prodigy P2 brake controller, part # 90885, shows the two dots, then the 7-way plug is the problem. If you still do not have the two dots on your brake controller when disconnected from the trailer, you will need to check the wires on the back of your brake controller. Follow these wires along the underside...

  • Brake Controller on Vehicle with Air Brakes
    A brake controller will work on just about any vehicle, regardless of the braking system it uses. The controller is tied into the brake stoplight switch that's usually located above the brake pedal, which is what tells the controller that the vehicle brakes are being applied so the connection is purely electrical, not hydraulic or air actuated. I would recommend a proportional controller such as the Tekonsha Prodigy, part # 90885. A proportional controller has an internal sensor that can...

  • Tekonsha Prodigy P2 Trailer Brake Controller Showing OL, PL and SH Error Codes
    First, lets start by resetting the Prodigy P2. With the trailer disconnected from the vehicle, disconnect the brake controller by unplugging the harness from the rear of the unit, and plug it back in. The display will show NC for 15 seconds, and then show two dots. The OL error code indicates that the Prodigy is drawing too much current. This is usually caused by a short on the brake output wire on the trailer or low resistance to ground on the brake wire. Look for any pinch points, or...

  • How to Install a Brake Controller on a 2008 Hummer H3
    Brake controllers can be used with virtually any vehicle so there are not many vehicle specific instructions out there. Underneath your dash somewhere is a bundle of 4 or 5 wires Red, Light Blue, Black, Dark Blue and possibly Orange. The Orange wire will not be used. The bundle is usually taped up in one of three places underneath the dash. Sometimes it is next to the center console by the gas pedal, sometimes it is above the emergency foot brake by the door and other times it is behind...

  • Recommended Brake Controller for a 1984 Scamp 16 Foot Trailer and Installation Cost and Information
    I prefer and usually recommend proportional style brake controllers. They brake more smoothly and vary the brake pressure depending on how hard you press the foot brake in your vehicle. The harder you press the brake, the more the nose of the vehicle drops. There is a pendulum switch inside the brake controller that senses this and sends more voltage to the brakes. Our best selling brake controller is by far the Tekonsha Prodigy, part # 90885. It is easy to use and very effective. I have...

  • Wiring A Gooseneck Trailer For Two Axles with Electric Brakes
    Only the blue wire is ran to the trailer brake connection at the rear of the vehicle. This wire should be 10 gauge. The ground for the brake controller is ran to the negative battery post or a suitable ground point on the vehicle. The grounds for the trailer brakes are connected to the trailer frame, the closer to the trailer brakes the better. If both of your axles have brakes (4 brake assemblies) then you will splice one wire from each of the magnets in the brakes to the brake feed circuit...

  • What Parts Do I Use To Pull a Trailer With Electric Brakes Behind a Kenworth Truck With Air Brakes
    You will need to install a brake controller on the truck, like Tekonsha Prodigy part # 90885. A brake controller has 4 wire leads coming off of it. The black will be wired to a 12V circuit, typically the battery, for power. The white wire will be connected to a good ground location. The red will go to the stop light circuit. Typically there is a switch that is activated when you depress the brake pedal that activates your brake lights and you can tap into a wire coming off that switch....

  • Power On the Ground Wires Going to the Brake Magnets
    No, you should not have current on the brake controllers ground wire when the brakes are applied and yes it should create a short circuit. It sounds to me as if you have a bad ground or a problem inside the brake controller. Brake controllers have no user serviceable parts inside them so the best action would be to replace the controller. I would recommend the Tekonsha Prodigy P2 Brake Controller part # 90885. This brake controller is easy to set up and is our best selling controller with...

  • Recommended Brake Controller for 2003 Dodge Ram 2500 Being Used in the Mountains
    What you have heard is correct. A proportional controller will certainly save some wear and tear on the vehicle and trailer brakes. A time-delayed controller will always send the same preset voltage to the trailer brakes, a proportional controller has an internal sensor that can determine how quickly and at what intensity the tow vehicle is stopping and then send the appropriate amount of voltage to the trailer brakes. This will allow the vehicle and trailer to stop at the same rate. A...
