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 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

Installation of Tekonsha Brake Controller Adapter

This adapter plugs into the 4-pin connector on your vehicle's built-in brake control wiring harness. The harness is located underneath the dash, to the left of the steering column, taped to another harness near the emergency brake pedal.

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

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

Video Transcript for Tekonsha Brake Controller 90885 Review

Today were going to review part #90885. This is the Tekonsha Prodigy P2 Trailer Break Controller. This is a proportional brake controller, which will activate your trailer brakes in proportion to your vehicles braking action. It will automatically adjust the trailers braking based on the deceleration of the tow vehicle, and it will activate immediately so theres no pausing like with your time-delay brake controllers. This controller does have an automatic leveling ability. Theres an internal sensor on the inside which will detect deceleration, even if the controllers not mounted flat.

You can position it at any angle, up or down in a vertical plane, 360 degrees, but you will want to be able to place it to where you can read this LED display right here. Now as far as horizontal position, you do want to stay horizontal and parallel to the direction of travel, so this way. In other words, not like this. Youll want it parallel that way. And not like that.

So as much as you can, and vertically you can go whichever way you want. Now there are three boost levels. Right here is the boost button. When you push that, it will put you into a boost 1, boost 2, or boost 3, and thatll let you adjust the initial braking power and aggressiveness, so if youre using a heavier trailer with a heavier load, youll want to increase the boost level. This controller also has a continuous diagnostic check, which will alert you to any potential problems.

It does have integrated safeguards, which will protect your vehicle, the trailer, and the brake controller. It does minimize drain on the car battery by drawing only 3.6mA when not in use. Itll prevent the trailer brakes from overheating by reducing power output to them during prolonged stops when your foots on the brake, and itll help defend the brake controller and the trailer breakaway system against any shorts. Right here will be the digital blue LED display, which is easy to read. Now in a minute here, Im going to hook the power up to it and well be able to see that.

On the very bottom here, which you can reach from the front, is a manual built-in rotary-style manual override for emergency braking purpose. Now on the very back, you can see the plug-in. It is a quick disconnect feature, which will let you easily remove and store the brake controller when not in use. It does come with this wiring harness that plugs into the brake controller and the pigtails to wire up to your vehicle. It does come with this type of mounting bracket, which will install with the mounting hardware to the side holes, or the popular pocket style, which you would mount this to your vehicle and then just slide this in, and on each side would be a pin that would slide into those mounting holes. To release it, you would just pull out those. It slides right out. There are also butt connectors to help you connect it to the wiring in your vehicle. We do also recommend that if you are going to move this from vehicle to vehicle, to buy an extra wiring harness and an extra bracket, if you dont use one of these. That way you have one in each vehicle and it makes it easier to remove the controller from one vehicle to another. We also do sell wiring harness that are vehicle-specific, meaning theyll have the plug like this n one end to plug into the brake controller. On the other end, instead of just these bare wires, theyll have a plug that will fit the factory brake controller port on your vehicle. What youll want to do is check the fit guide, if you do have the factory brake controller port, on our website and it will give you the part number of that vehicle-specific brake controller harness. This is designed for trailers with up to four axles or eight brake assemblies. It is designed for use with electric or electric-over-hydraulic trailer brakes. It does come with a limited lifetime warranty. Now what Im going to do is, Ive got a power source here Im going to connect the wires up to, so we can get an idea of that blue LED display and just some of the features. Ill show you how they operate on the controller. Ive got them all hooked up to the power source. Now Im going to snap this in. Im going to turn the power on. Now what youll see, is when the power comes on, youll see a C. Youll see a dot and a C. That means the trailer is connected. Now if the trailer wasnt connected, let me just disconnect this and Ill show you what it looks like, youll see itll flash N-C and that means not connected. Whatll happen is thatll flash for about fifteen seconds, then it will change to just the two dots, and that means you trailer is not connected. Ill show you here in a second. There you go. Now youre just seeing the one dot. Therell be two dots if the boost feature was engaged. If it isnt, theres just one dot. What were going to do is connect the trailer back up. There we go. Now youll see it is connected. Now this boost feature button right here, now youll see when I push it once, itll say b for boost. Now right now it isnt in any boost level, as youll see by just the dot and the C. Now when I hit boost and I go to boost 1, and then theres a boost 2 and a boost 3. When Im in a boost level, watch when that goes off, you should see a dot, a C, and a dot. Therell be two dots. That means the boost feature is engaged. Now to set the power, heres the power over here. If you push this manual override all the way on as far as you can go, and you turn that knob, and thatll set the boost or the power that you want. So lets say we set it at, lets say 6.3. Now I let off the manual override. So basically when you go to hit this manual override, as you push it, its going to ramp up and itll go all the way to 6.3. Thats the power you set it for. So you just set your power control, the dial there, by pushing all the way in and set the power. Theres a feature, if this is connected and its just sitting with no motion or activity for 15 minutes, it will go blank. It still has power connected, but itll go blank just to save on the power going to it. That should do it for the review on part #90885, the Tekonsha Prodigy P2 Trailer Break Controller.

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. 122727

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 9444


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.

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.

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 188777


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!!! 117534


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.

So I purchased a Tekonsha p2 brake control recently after hearing good reviews from friends. After a few weeks of having it installed I have a few gripes: 1. Display - The LED display is super bright and there is no way to turn down the brightness. It is really distracting to have a flashing bright blue light shining up at you at while driving at night. If you are the kind of person who is bothered by a GPS/Phone screens while driving at night then this this will bother you. 2. Wiring - Tekonsha's wiring instructions tell you to wire the brake controller directly to the battery. If you do this the brake controller runs 24/7/365 even when the vehicle is shut off. Do you really want a constant drain on your battery? Instead I chose to use a relay to turn the brake controller on and off with the ignition. It would have been nice if there was a relay included or at least optional wiring instructions. 3. No Off Switch - My previous gripes wouldn't be that big of a deal if you could just manually turn off the brake controller when not in use. But for some asinine reason there is no off switch. So if you don't want the brake controller draining the battery of your parked tow rig, or are tired of the blue light blinding you at night you will have to climb under your dash, remove the brake controller from it's holster and then disconnect the wiring harness... 30936


There is an automatic shut-off built in to the controller. After a period of time, it will shut down on its own. It will not drain the vehicle battery if wired according to the instructions.Also, try the bracket instead of the holster. With the bracket, you can rotate the controller so the display is not directly aimed at the driver when not used.

Patrick B - 11/30/2012


David, Thanks for the comment on the blue LED. I am sensitive to the Blue. My eyes no longer can quickly adjust to differing light intensities. I can see in the picture how the blue affect the camera. So I will not buy this one. My old Tekonsha had RED LEDs. I should have kept it. Red is PERFECT for night vision. Red does not interfere with night vision. Thats why its widely use for night time illumination.Blue, absolutely not. Disappointing.

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. 239604

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. 137307

Seems to work real well but, I can't really judge to much for My trailer's breaks haven't been used for years. Installation was quick. It took about 15-20mins without my trip to the hardware store for an 8mm nut. Tried it out on my trailer and once you get the adjustment right, it works real well. Definitely worth getting a break controller for whatever trailer you tow and this one is real nice. 77404


Ive owned this for about a year now and have gotten the kinks out of my campers breaks. They seam to work real well with it. I seem to be able to break without the nerve-racking stress I had with the old truck. Proportionality control also is handy going down long hills or in heavy traffic. most of the time I have it in Normal mode dialed to the instructions in the manual. I would Highly recommend those without a break controller get one and this one is, so far, excellent.

I installed this in a 2006 WK Jeep in about two hours. I used the generic pigtail because I didn't have/couldn't find a vehicle specific connector. There are more specific instructions for wiring it online, be a little creative with your search. I was able to find the same sheet as the generic one packaged with the controller, just specific to a 2005-2010 Jeep Grand Cherokee. The install took me about two hours, working by myself, and was relatively straightforward. Much of the time was taken up by making the install of wire runs neat and preserving the "factory look," if you are not particular about appearance, the install could go much more quickly. This was my first time installing a brake controller. I haven't had a chance to hook it up to a trailer yet, but it seems to be functioning properly. I am a little concerned that the ground wire on the supplied pigtail is a small gauge, 14, so if I encounter any issues I will switch this out with a larger gauge wire. I also noted that the factory wiring harness supplied by the Jeep dealer for the hitch has a 14 gauge brake wire. While this should be sufficient for up to two axles, if I notice any issues, I will replace this wire also with a heavier gauge. The generic pigtail contained a 12 gauge wire for the brake line. All around, so far very pleased with this purchase. 72226

Product came with great online video on how to install on my Chevy Avalanche. 4 wires under dash and 1 under hood. All connectors required came with the product. It has great electronics that tell you if the trailer is hooked up and how much braking you are using. Easily to adjust. Can take it out by removing one plug when not pulling trailer. Only thing missing was instructions stating that the unit turns off after 15 mins after ignition is turned off. I was worried about battery drain. Not to worry. Called tech support and they answered this question. Pulling a single axle trailer with varying load weights from 1000-2000 lbs. good instructions on how to adjust after install. Wish everyone selling on the web was this thorough. These guys have done their work. 147507

The Tekonsha Prodigy P2 brake controller is a great product. This is my second one to own. Shipping was prompt and installation was easy. One thing I really like about is the installation videos. It helps me decide if I can do it myself or not. However I did find one small error video demonstrating the installation of the Prodigy brake controller in the 2012 Silverado pickup. When hooking up the power to the controller under the hood the video states that you need a 10mm 1.25 pitch nut to go on the stud. It is easy to find. I found one at Home Depot. The only problem is it actually takes an 8mm 1.25 pitch nut. This caused only a slight delay in the installation and another trip to get the correct nut. Overall I’m very satisfied product, the service, and the price. …and I really do like the video instructions. 44810

Really like the brake controller. Pulled my daughter/ son-in-laws trailer to their seasonal sight with boost off with no problems. My trailer weighs 2500 pounds more and getting good operation at boost1 setting. A snap to adjust. E-mailed a some questions when I first started looking and Nicole answered the same day with a couple questions for me. After I responded she sent her recommendations a few hours later with a link to an installation video. Terrific service. Kind of stumbled on your site looking for something else, sure glad I did. Looking at towing mirrors for Suburban and a hitch for the other car next. 130280


Works very well. The ability to adjust and ease of doing so is a great feature.

2013 Chrysler Town and country White wire with green stripe worked for cold side of brake switch. When you cut a hole in the boot, to pass the wire from the engine compartment through the fire wall, make it at the 2 oclock position when looking from the front of the engine. this makes it easier to pass the wires. Check the free led circuit tester prior to use. Some don't work. Use a piece of aluminum angle stock to mount the circuit breakers. Mount the aluminum to a 10MM fender bolt next to the fuse box. This way you don't need to drill holes. Was a good kit with good components. 83238


Has been working fine without issues. Adjust it once and it stays put.

This was exactly what I needed for my 2005 Tacoma for towing. I pulled a 29' camper trailer 300 mi. with it shortly after installing. With the proper hitch setup and this brake controller, it turned what could have been a white knuckle nightmare into a pleasureable trip. I purchased this with the proper wiring plug-in adapter which made it extremely easy to install in less than 20 min. The only thing I don't like about it is how intensely bright the blue LED lights are at night when I'm not towing anything. Of course its fairly easy to unplug and remove when not in use though, but that does get old. I wish it just had an on/off switch or something. I was initially concerned that the lights would put a drain on my battery as they do stay illuminated after turning off the truck, but I found it's only for a few minutes then they turn off. Overall, I would recommend this controller, and I would buy one again based off the last 9 months of use. 64563


My 2005 tacoma has the factory installed 7 pin plug, did yours? Im about to pull a 26 trailer at about 4500 lbs. Has the Tacoma performed well since your original post?

Can't say enough for The big selling point for me was the incredible number of help videos on their site. I didn't feel a need to read the directions since their installation video was very clear. We are currently getting four trailers updated for DOT inspection, so I'm sure I will be back. 115144


They are still working great. We were under the gun at the time trying to comply with new commercial vehicle rules, and your products AND ESPECIALLY your website was a very valuable resource. Your tutorials are awesome. Thank you for being a resource rather than just a retailer.

The Prodigy P2 is as easy to install in my 2011 Chevy Silverado as any brake controller I have used. This is a direct wire install with now extra wiring harness used. It took me about an hour in 90 degree heat under the maple tree. I had to buy a fuse and nuts for two studs under the hood of the Chevy. Total cost was $6.49 for the extra parts needed. 89676


I just completed a 4400 mile trip to the western states of the US. I was towing a 6 by 12 cargo trailer with electric brakes. My Prodigy Brake Controller worked flawlessly the entire trip. I recommend this product.

I ordered this unit along with the vehicle specific interface adapter, 4 pole to 7 pole trailer connector. I had my own 10ga wire and split loom to run from the back of the truck to the front. Took some time but got the job done. I suggest that you go ahead and spring for the 10-2-1 duplex wire that etrailer has available so you don't don't have to take the time to feed the two single conductors thru the loom (I strongly suggest using the loom if you do this yourself). Once connected and powered up it took all of 5 minutes to setup. I ordered the Tekonsha P2 along with all the necessary equipment to "turn key" the project along with an oil cooler on a Friday night. Saturday morning I was notified that the order was already packaged and ready to ship along with my 5 business day shipping being upgraded to 3 business day shipping. As stated my order arrived the following Wednesday. Now that's customer service. Packaging was great. Thank you etrailer. I will order from you again and I am recommending you to everyone I know. 98844

This is my first brake controller so that fact may disqualify me as a reviewer; but then maybe it makes me a better one! I usually do a lot of research before buying something I need that I know little or nothing about, but that was a quick task in this case. EVERY forum, expert review, and installer recommendation had the same two pieces of advice: Buy proportional versus time delay, and buy Tekonsha. Beyond that, it was either buy the Prodigy P2 if you don't need an LCD display or the P3 if you do. I didn't need the LCD display because I'll only be hauling one trailer with the same drag car on it, so now that I have the controller installed and adjusted I don't expect to have to mess with it any more. Installation was easy peasy with the adapter cable for my '10 Tacoma, mounted under the lower dash just beneath the steering column. I did add two slightly beefier sheet metal screws to the dash mount as the two screws provided seemed a little weak. Solid product, works great, took all of 15 minutes to adjust. 44806

I purchased the P2 along with cable for my F150. Installation was very easy. The instructions were clear with excellent drawings. I then connected my trailer to test the controller. All the functions work correctly. My next step is to drive the trailer as the instructions indicate to fine tune the boost level. Once I have done this, I will update my review. The instruction card is made of light card board and is designed to be carried in your truck for quick reference. Instructions for using the controller are clear, concise and easy to follow. I contacted customer service prior to placing my order as I was unsure if I needed the P2 or the P3. The sales rep was very knowledgeable and quickly determined after a few questions that I needed the P2. There are other, less expensive controllers to choose from, but if you read the reviews, they are not as well made as the Tekonsha is. I highly recommend spending a bit more for a product that will last and provide excellent service. 166000

Received my Prodigy 2 but haven't put it to use yet. Price was comparable and the order arrived on time. The email feedback before I ordered it and the attached instructions and video were dead on and made the install a piece of cake. Customer service is excellent, received updates on my order throughout. Will definitely be back and gladly refer! 117019

Ordered the controller with a wiring harness for a 2012 Nissan Titan with the factory tow package. Quite simply Plug-n-Play. Located the factory harness connector inside the dash to the left of the steering wheel behind the lower trim panel (two phillips screws and pull straight out), Plug in the harness, mount the controller, plug it in and ready to go! If you know where you want to mount it, the install is 15 minutes max! is great, shipping was quick, packaging was great and the order was correct. The quality of the products was excellent. 48102

Hey Patrick, thanks for the follow up message. I am still liking the purchase I made , the mirrors are wonderful and still working as they should with weekly use , and the brake control box is also doing what its supposed to be doing and is used weekly also . I am happy with the purchase I made and will for sure use for future items on this truck and the others that i own .

Application: 2004 Chevy Tahoe LT / Pulling RV Camper My first ever review of anything purchased online and I figured this one really had merit to deserve the extra attention in giving credit where it's due.. Easy and efficient online ordering processes, excellent customer service and the follow-up email after the sale and delivery of the product was the icing on the cake! You guys' have really got it together over there and I'll be ordering from you again very soon! Thoroughly impressed with the quality and extra-nice features of the unit! Perfect fit installed just as quick and easy as the product's description and related installation videos have shown. Works much more smoothly and predictably than the old Kelsey-Hayes slam-bam brake modules I've used in the past. Especially love the progressive braking feature too! Thanks again for the outstanding customer service and superb product quality! "I'll Be Back!" 144029

I chose this controller after doing days of research online and in talks with friends who have trailering experience. The balance between cost and performance seems to be reached perfectly in the Prodigy 2. It was easy to install thanks to the video provides on its website. I ordered it about 7PM and immediately got an email confirmation. About 1/2 hour later I got a second email telling me the item had shipped and that I had been upgraded to Express Shipping at no extra charge. Two days later I came home from work to find that the controller had been delivered and I had it installed before my wife came home from work. It took me no more than thirty minutes with the hardest part being locating the almost-hidden connector under the dash of my 2005 Toyota Sequoia. Worked perfectly the first time, and the instructions were very clear on how to set it up to work best with my trailer. Highly recommended. 30700

Arrived on time and works exactly as described. I installed this on a 2007 Landcruiser. The most difficult part was finding instructions on where to find the plug. After much research, I came across Ih8mud and got the instruction on where and how to connect. Rather than mounting it to the dash, I removed the ash tray and put it in that spot. It fits perfectly. 177372

This was a replacement for a similar product from a manufacturer etrailer no longer carries. The previous product randomly turned on the brake lights on my 2010 Tundra while it was parked at night; they might stay on for some minutes then turn off. Tapping the controller unit turned them off at first, but then nothing worked except unplugging the unit. Then it totally crapped out. Contrast that with the Tekonsha P2 unit. No defective operation, easy installation, great display with clear diagnostic significance. I mounted the unit with Velcro strips( buy them at the fabric shop) super glued to the unit and the vinyl of the Tundra, on the left side by the left knee. Did I say really quick delivery and great communication from etrailer? You can't go wrong, and the online communication and discussion is worth a lot. The unit also makes the trailer brakes work,like it should. Recommended 26429

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. 243826

Very simple to install. It came with a 4 wire harness with a receptacle on one end to plug into the back of the unit. The ends of the wires were stripped and ready to attach to the wires already under my dash. It included 4 crimps to connect the wires. My truck had 4 wires and so did the unit. Directions were easy to figure out what wire got hooked to what wire. Usually every time I buy something like this it will have 40 wires and I have to figure out which ones to use. This could not have been easier. In fact the hardest part of the whole thing was trying to decide where I wanted to mount it. The wires are ling enough to reach halfway across the dash. If your truck is prewired this unit only takes about 5 minutes or less to install. I am goijng to use the unit tomorrow for the first time. With all of its features, I am sure it will be great. If not I will write back. 26165

Installed it in a 2008 Dodge Sprinter 3500 RV that already had a factory hitch and 7 pin wiring and connector installed, but only completely wired for 4 pin operation. It installed exactly the same as the etrailer installation video for a 2013 Mercedes Sprinter by connecting it up to the pre-wired OEM trailer brake connector found under the drivers seat The only change I made was to cut the OEM connector off and butt splice the wires because some were different gage wires and I didn't trust a 12ga wire connecting to a 14 or 16ga wire using 12ga splice lock connectors. It was so nice it had the OEM pre-wiring for trailer brakes! Haven't connected it to a trailer yet, but it tested out ok using a Tekonsha trailer emulator. Just note that you wont get full trailer emulation unless you have 12V hooked up to your 7 pin connector on your tow vehicle. 158700

The Brake controller arrived promptly and worked as expected. If you are shopping for trailer accessories buy it here at etrailer. I found etrailer when I started searching for a brake controller for my truck. Their install video was one of the first search results when I searched out my vehicle which led me to their site which had all of the information you could want. Not only did they have install videos for my specific vehicle but for just about every vehicle application. When shopping on their website you are treated to install instructions as well as the video install instruction for your application as well as installation tips. Many reviewers also upload pictures of their installations giving you lots of ideas for your installation. A simple search lead me to etrailer the wealth of information convinced me to buy from them. 154471

I ordered the Tekonsha Prodigy P2 Brake Controller along with a Draw-Tite Ball Mount, 2 5/16" Chrome Ball and Pin lock on a Sunday and it was delivered the following Friday. The Tekonsha Brake Controller came with a DVD and with aid of Video for installation instructions for 2011 Chevrolet Silverado (mine being 2010) on ETrailer site, I was able to have installation within 2 hours. Easy to follow instructions on where to find wiring on my vehicle under dash and hood assisted installation immensely. After installation and testing the Brake Controller with trailer attached everything worked as required. I was quite pleased with ease of installation for this not so handy novice. I have skimmed through Etrailer's site for other accessories for truck and trailer and other products have interested me. Thanks ETrailer for your products!! 34780

I rated it as high-good because I haven't installed it yet, but I have convidence it will work well and should rate an "excellent". The product and installation parts/instructions look to be first class. It will be installed on a Dodge Dakota used to tow a Casita RV trailer. I bought this on advice of several other RV owners that all agreed that it is the best you can get. It will be replacing a time delay type controller that frankly I just cannot stand. The fact that it has an inertia sensor that is not a pendulum is the #1 reason I chose the Prodigy over others. According to the instructions, it does not have to be mounted level and internally self adjusts for tilt while going up and down hills. I find that to be fantastic and can hardly wait to try it out later this summer on a trip across the Rocky Mountains. 13904

Where can I find out what the codes mean? Mine is saying 5H

comment by: Dan - 09/07/2014


According to the installation instructions that are linked on the right hand side of the page under the add to cart icon. The code of S.H (looks like 5H), when blinking 2 times per second indicates that there is a short. Specifically the short is on the brake wire, and is occurring while at idle condition. To begin trouble shooting you will want to use a circuit tester and isolate the issue to the trailer or the tow vehicle. I would start by testing the brake location on your 7-way (5 o'clock position) to make sure that the trailer is getting signal. Then you can proceed to trouble shoot depending on if the issue is on the vehicle side or trailer side. If the issue is on the vehicle side, I recommend checking the brake controller and make sure that is it getting and sending brake signal, if so then check all the grounds associated with your wiring. If the issue is on the trailer side I also recommend checking all the grounds, as well as the brake magnets grounds. Also check for any signs of damaged wiring that may be causing the short.

And reallyy good quality product, works well, and the boost feature is a great idea and helps provide smooth controlled stopping of even the heaviest loads. The wiring harness provide by eTrailer worked perfectly and the installation video was really most helpful. They even include the end to end connectors. My only complaint was more to Chevrolet not including the ability nuts to fasten the connections in the engine fuse box terminals. I spent nearly 4 hours running to different auto supply stores and hardware stores trying to find the correct size. I even called my local dealership and they couldn't help me. Excellent product! 56254

Great product and good price. I found a slightly cheaper price but the site didn't have the great installation videos so I figured if Etrailer went to all the work to share the videos then they are the kind of company that cares about how well the products work and will have great customer support too. I didn't have the non contact tester like in the video and to work under a dash you have to stand on you head so I googled “car alarm install diagram” and found my car and checked on the list for “brake” and it showed which wire by color code was the right one to tap into. I then just used my cheap 12 volt tester to verify and it worked great. IFY 1999 Jeep Wrangler the brake wire is white with brown stripe. Thought this might help someone else. 19374

  • What is the Difference Between Prodigy P2 and P3 Brake Controllers
  • The biggest differences between the Prodigy P2 brake controller, # 90885, and the P3 brake controller, # 90195, are the display, buttons and look of the controllers. I like the buttons and display on the P3 controller myself because the display uses actual words for setup and troubleshooting rather than the display codes that the P2 uses. This makes it easier for me to know that I am adjusting the correct function or see the trouble shooting codes without referring back to the installation

  • Trailer Brakes only Work When the Manual Override Lever is Activated on a P2 Brake Controller
  • It sounds like the P2, item # 90885, is not properly connected to the vehicle stop light switch. Since the brake controller has power and the trailer brakes work properly when the manual lever is activated, the black blue and white wires are connected correctly. You will need to connect the red wire from the P2 brake controller to the cold side of the stop light switch. Use a circuit tester, item # 3808 if needed, and find the wire at the brake switch that has power only when the brake

  • Where is the Brake Light Switch Wire for Brake Controller Installation on a 1998 Chevy C/K Pickup
  • I do know the wire you are looking for. It should be above the brake pedal. Usually, on Chevy and GMCs like your 1998 C/K, the brake wire that carries the brake light signal is white. On some occasions, it will be yellow. So I would first look for a white wire on the brake light switch and test it with a circuit tester like the Quickee Circuit Tester # 3808. You know you have the right wire if it carries a signal only when the brake pedal is pressed. If that is not the right wire, try

  • Brake Controller Plug Location on a Class C Motor Home Built on a Ford E-450 Chassis
  • I spoke with my contact at Tekonsha and he informed that you are looking for a brown 6 pin connector behind the hood release, up near the firewall to plug in the Tekonsha Plug-In Wiring Adapter # 3035-P. He said there is also a gray connector that is very similar to the brown connector that the # 3035-P will actually plug into but it is not the correct one to use. The Tekonsha Prodigy P2 Proportional Brake Controller # 90885 and the # 3035-P Ford Super Duty Adapter is what you need.
