Proportional brake controller automatically levels when mounted within a 360-degree vertical range. Includes digital display, 3 boost levels, battery protection and continuous diagnostics. Easily transfer between different automobiles.">vehicle GVW
*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.
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:
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.
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.
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
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.
Install your electric brake controller quickly and easily with this custom wiring adapter. Simply plug one end of the adapter into your brake controller and then plug the other end into the built-in harness beneath your vehicle's dash.
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.

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

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
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

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
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
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

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 etrailer.com 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

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
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

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 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

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! etrailer.com is great, shipping was quick, packaging was great and the order was correct. The quality of the products was excellent. 48102
this unit hooked up just as the video had shown and works great 90980
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 etrailer.com 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
Finally got around to putting in my Prodigy P2 brake controller. Installation was simple and easy and it works great. I would highly recommend it to anyone looking for a brake controller. Thanks to the guys at e-trailer for help with the order and installation videos. 76534

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

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

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

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

Very pleased with the purchase of this brake controller. Easy to use, exactly what we needed! 74812
by: Shawn M10/03/2012
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
by: Walt Z07/13/2011
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

Two Phillips head screws to remove lower dash panel, Infiniti had the wires labeled with a huge sticker that said "ELECTRIC BRAKE CONTROLLER" I cut the tape to bring down the wires and this thing plugged in perfectly!!! Now we are 1800 miles into our trip with this brake controller and it has been OUTSTANDING!!!! AND I CANNOT BELIEVE HOW EASY THE AFTERNARKET WIRING HARNESS WAS TO INSTALL!!! Soooooo Impressed!!!! I can give this prodigy controller AND THE WIRING HARNESS a review of 6 out of 5 stars!! The dealership wanted $320 to install it for me. I lit my morning cigarette at 4:55am and the entire install was finished before i smoked my last puff of it at 4:59am!!!! THANK U FOR MAKING IT SO EASY!!! 127383

I installed this Tekonsha brake controller on my 2014 Chevy Silverado 1500 4x4 in about an hour. The actual install of the controller to the underside of the dash took only about 15 minutes but mating the included harness with the one that came with my truck added a little more time. Matching the cables was pretty easy as the controller came with excellent instructions (but If I had to do it over, I would probably buy the optional vehicle-specific harness just to save a little time and to insure a good connection.) I haven't towed with the controller yet so will need to add some comments about actual operation in the near future. By the way, the install video by etrailer.com is excellent. 112437

Installed this along with my universal connector for my 2014 FJ Cruiser and everything worked great. Linked up the travel trailer and got on the road, quickly dialed in the brake setting per the supplied instructions and I was off. I later ended up having to reduce the brake setting as my travel trailer is so light (2,500 lbs loaded) that the brakes would lock up when I was about completely stopped. The brakes on the trailer are older and not sure if that has anything to do with it, but dropping the brake setting by 0.5 seemed to do the trick and stopping is still a breeze. I'm not sure what more advantages there would be with the P3, but the P2 worked perfectly for my setup. 154840
Do your homework first. I found this website by chance, and boy am I glad I did. I was originally quoted $250 for the trailer brake and got it for half with etrailer. It strongly recommends that you buy the installation kit. You need to look to see if your vehicle already has a harness, which mine did. You can buy a wiring adapter for about a third of the price as the installation kit. Again, doing some research will save time and money. As for installation, saying that it took five minutes is almost exagerating. I just attached the mounting bracket to the truck, attached the controller, and plugged in the harness. I will definately use e-trailer for my next purchase. 19378

It was time to replace my 20 year old Teconsha brake controller. It served me very well however the technology available today gives a much better Towing experience. I settled on another brand because of time constraints. It also cost less money, who doesn't want to save a few bucks? WHAT A MISTAKE! After one short trip of fighting the inconsistent operation of the other brand, I called etrailer and ordered the prodigy P2. It stops the trailer in perfect unison with the truck EVERY TIME. I can see the display even in bright sunlight. I love the manual lever on the bottom. It gives full range and precise control when you need it. Thanks etrailer and Teconsha, WORTH EVERY PENNY! 142745
Tiny profile, 2 mounting options allow choosing type of mount given locations available. Ability to mount in a non-horizontal orientation also greatly helps this. For my open top Wrangler I like the 'holster' mount so that I can easily and quickly remove it to lock it away when I'm not around. All wiring was straight forward except for the attach to the brakeline, but given this varies by vehicle and year that's not the products fault. Some internet searching for my vehicle make and model wiring schematics allowed me to figure that out without too much issue. A electrical 'tester' also helps with this. Lot of functionality in a small package, I look forward to using it! 47202

I purchased the Prodigy P2 and the required connecting cable just before the 4th of July. The order was shipped on Saturday the 5th and I received it on Wednesday the 9th, one day ahead of the scheduled delivery. I installed it on Saturday morning and it was quite easy. It took about 15 minutes in all. I replaced a Reese time delay controller which was very jumpy at times. I tested the new controller on Monday and it works very well. It is pretty smooth and seems to eliminate the jumpiness that was inherent in the time delay of the old controller. I still need to make a few more adjustments when we hook up for our next trip. Thanks eTrailer for a great price! 141423

Extremely easy to install. Had a harder time deciding exactly where I wantedon it. Took all of ten minutes to completely attach unit with the plug in adapter. Worked the first time out, no fuss. Instructions for picking the break level very easy to follow. Would recommend the product and definitely the etrailer company in general. Phone staff was very courteous and answered all my questions, online ordering was easy and delivery prompt. Etrailer saved me close to $100 from what was being quoted by my local companies to purchase and install and inferior product. Thanks Etrailer and keep up the YouTube videos. A very satisfied customer. 32988

Excellent business with etrailer.com. Brake Controller and wiring kit arrived within 72 hours of placing the order. I had never installed a brake controller before; however, between the instructions provided and the numerous technical videos on the website, it made the installation very easy. My only improve would be for the installation kit to also include some sort of clip to attach the wire to the positive post of the truck battery. The actual Prodigy P2 brake controller seems as advertised; however, I have not used it yet except during the initial testing of the installation. I will definitely do business with etrailer again. 31789

Outstanding product. Installed on my 2009 GMC Yukon. Found the wires under the dash, hooked up the brake controller wires, plugged in and took trailer for test drive. After a minor adjustment to setting, works like a champ! Well worth the money for what you get. BTW, I tucked the wires into the left side compartment of the dash and installed a rubber grommet to allow me to take the wires out of the top of the access door and plug in to the back of the BC while hung on my front window using a suckshun RAM mount. Makes it easy to de-install and hide when not in use but quick and easy to re-install when time to hook up the trailer. 14147

Prodigy P2 Controller/2000 Toyota Tundra I wanted a good controller for my 2000 Tundra to control new electric brakes on my 32 ft sailplane trailer & on a 29 travel trailer. I did a lot of i-net research & decided on the Prodigy P2 from E-Trailer. I wanted a progressive controller. The P2 has not been installed yet but it seems well constructed & has a lot of good features. It also comes with a pigtail for easier installation & removal. The E-Trailer site has a wealth of "how to" information, good prices, & I could get everything at one place. I am now confident that I can do a nice installation & that it will perform well. 4248

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

I was utilizing this same unit on my 2004 Nissan Titan pulling our 25' travel trailer on the freeway when a pickup truck lost control and ended up perpendicular to us in our lane. We did hit her but being able to rifle the brakes and have the trailer do the same we all walked away and the trailer never veered from it's direction. I don't know how much this contributed to our positive outcome (except for the Titan) but I am very thankful that this brake controller works under the most dire of circumstances. I was able to pull it out of my truck before they towed it away for good and will go in my new one. 47871

P2 installed. 33214
This thing is really neat. It took me about 7 hours to get the whole thing done. I know, I'm slow. I had a loose connection in one of the wiring clamps, replaced them with twist clamps. Then I had to calibrate the power by driving 45 mph with some manual brake on to warm the brakes. Then 25 mpg repeatedly applying full manual brake to try and lock up the trailer tires. This was kind of fun and it's all working great now. This is a lot of new information to work with all at once with the wiring, drilling, calibrating, etc. If I had know, might have paid the $100 to have someone do it. 45374

The installation of this brake controller was easy, especially with the ETBC7 wiring kit. Shipping was fast. These people are great to do business with and I would highly recommend them. Thanks. 20123
I bought this controller to replace my old one, which was a Prodigy also. It was the best controller I've ever owned or used. It had been on my F-250 Power Stroke for many years (10 or more). My odometer is showing 226,000 + miles and a large portion of those have included a trailer of some type. I pull a lot of different trailers and pull very often. There has been times when someone would be riding with me and they would comment that they didn't think my brakes were working because they were so smooth. When I have 10K-12K pounds on a trailer I don't want to trust any other controller!! 66016

Great product, great website, good price and quick delivery. But the thing that made the purchase really worthwhile was the ability to find a video of how to install this specific product on my particular truck. The 2011 GMC Sierra comes with a bundle of wires tucked under the driver's side of the dashboard. The video from etrailer easily found on You Tube shows exactly which wires from the truck to connect to the wires on the brake controller. This job would be impossible for the average guy to do without the video. I would definitely do business with etrailer again. 13217

Never had a brake controller before, so I can't compare this to anything else, but it worked flawlessly for me. Easy DIY instal (once I was able to get the electrical wires through the firewall). This unit can be installed tilted upwards more than most of the other controllers (stills needs to be parallel to ground), which made for a nicer, easier instal in our Sienna. That is a HUGE plus in my opinion. Easy to set and use. Display is nothing fancy, but gives important info and is easy to read. Once it is set, you will not need to look at it much anyway. 16953

No problems with the brake controller, and thanks to the video on etrailer showing where to locate the leads under the hood I was able to do it myself. The lead under the fuse box was not taped near the fender, but stuck under the box!!! After watching the video I knew not to remove the box which would have been my first course of action. After a lot of pulling (gently) and tugging I was able to free up the wire. The video may have saved a very expensive repair to my Avalanche. Plus shipping was faster than expected. Will buy more products in the future. 23727
