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.

2011 Ford Ranger

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!

2013 GMC Sierra

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

2006 Jeep

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

Chevy Avalanche

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

2012 Chevy Silverado

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

2013 Chrysler Town & Country

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.

2005 Toyota Tacoma

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?

2011 Chevy Silverado

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.

2010 Toyota Tacoma

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

Ford F-150

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

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.

2005 Toyota Sequoia

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

2010 Toyota Tundra

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

2010 Chevy Silverado

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

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


Shawn,I agree completely, only problem I have with your post is you didnt list the sizes either so Im still on the hunt!

You will need 1 M8-1.25 nut, see part 185917. You will also need an M6-1.0 nut, see part 185916. We have videos about these installs so you can see where the connections are and where to find the wires.

1999 Jeep Wrangler

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

2011 Toyota Tacoma

Nice product. Was easy to install even in a 2011 Tacoma without towing package. 114138


This controller has worked very well on my 2011 Tacoma without tow package. Its simple to operate and has been very dependable so far. Great doing business with etrailer.

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

2014 Chevy Silverado

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 is excellent. 112437

Jeep Wrangler

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

2000 Toyota Tundra

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

2004 Nissan Titan

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

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

2015 GMC Sierra

As with the review for the plug in wiring adapter on my 2015 GMC Sierra the etrailer video was extremely helpful. I chose to install the controller on the left side of the steering wheel, and fairly high up, where I thought it would be easier to see and access if needed. Maybe so, but it was also a bit in the way getting into and out of the truck and I ended up whacking it a couple of times with a knee when I wasn't paying attention. Not good, so I eventually moved it back to the spot that etrailer used in the video and it works just fine. 208942

This unit is replacing a time delay brake controller originally on my F-250 Super Duty. I had put one of these on my other F-250 3 years ago and was extremely pleased with the smoothness and operation. It was a snap to install since the trucks already have the harnesses and 7 pin connectors in place. I use it with trailers that average 7000 -8000 pounds and dual axles. And as always, etrailer had the best price and fast delivery as well as someone who could quickly answer my technical question about replacing the old time delay controller. 131195

2011 GMC Sierra

I ordered this controller for my 2011 GMC Sierra z71. I finally pulled my car trailer this weekend and let me tell you, it made a world of a difference. I no longer have my trailer pushing my truck when I'm slowing down. The only downside is trailer doesn't recommend you buying the 2 nuts to hook to the fuse box terminals. Also you will need a 40 amp fuse for it to work on a gmc or Chevy. Other than that I am very please with the overall product. The blue led display isn't as bright as some of the people said it was on here.! 193804

2012 Chevy Silverado

I have a 2012 Chevy Silverado 4x4. I already had the trailering package on my Silverado which was pre-wired. I watch a YouTube video about installing this product on my year Silverado. If everything was as easy as installing this product on my truck, the world would be a better place. I would recommend, no HIGHLY recommend this product to anyone looking for this type of equipment. The support from etrailer, reminds me of how business was many years ago. My thanks for fast shipping and just the interest in my purchase. 218986

The product is very simple and strait forward, 4 wires and a couple fuses and it was ready to run. I put this in my 2010 silverado 1500, got the instructions from etrailer witch were spot on. I haven't used the controller yet but the build quality seems high and I'm confident I won't have any problems. 199028

2011 Porsche Cayenne

I installed this on a 2011 Porsche Cayenne that has the factory trailer hitch option. Wiring was installed by the dealer and took about 2.5 hours. The product works intuitively with good tactile feel when adjusting or operating manually. The easy to read display works great. The boost features are just what I need for my towing needs, where my towing weight can vary greatly. This product has met my expectations. The e-trailer staff was helpful and the order process was smooth. Thank you! 232774

2009 Chevy Silverado

The installation video that was available on your website was very accurate in showing where cables were located and what needed to be done. The installation into my 2009 Silverado took about 30 minutes wich is about what the video indicated. I've used my new Prodigy P2 controller once and it is wonderful. I can't believe how smoothly it works and eliminates those jurky stops from the trailer. It is quick and easy to adjust / fine tune for each use dependant upon trailer load. 84263

2015 Jeep Grand Cherokee Laredo

The instructions, videos and harness to get from 4-pole to 7-pole all were extremely helpful in getting this connected and operational. no issues with the parts from e-trailer and the "how-to" videos were great even though my particular make, model and year was not covered it was still very helpful. I only wish that Honda would have better accommodated this type of install in their older model (prior to 2009). Both the brake controller and harness are working well. 22534

Just put my brake controller in my truck, hooked up to my horse trailer and it works great. I have a 2010 Silverado and the video you have for my truck made the job so easy and trouble free.What a great job showing the wire connections, what fuses to use, where they went in the fusebox and even told what size nuts to use to connect hot wires to the fusebox. Great Job!! 37261

2008 Scion

Fabulous product. My son installed this on our 2008 Scion XB. He had to use the wiring kits from etrailer and totally wire it from scratch. I highly recommend this brake controller. It has all the options and then some. Very safe and easy to install if you know what you are doing. It will mount in any of 360 degrees making it easy to find a good place for it. 50641

I purchased a combo wire stripper/crimping tool from local hardware store and, after watching your installation video for the 2006 trailblazer with factory installed 7 way , I installed this product with no problems in less than 30 min. No previous experience. Best of all when I rented the horse trailer and plugged it in to my vehicle everything worked. 129224

2005 Toyota Tacoma

The 3040-P cable plus the 90885 electric brake controller were perfect for my 2005 Tacoma quad cab manual shift truck. I just had to take of the plastic cover bordering the front of the drivers door and the floor. That exposed the white connector. I then removed the fuse box door and used that opening to mount the controller. 140002

2014 Toyota

Worked just as described in the video. Hooked it up in a 2014 Toyota Tundra. The only hard part was putting in the screw on the right side - just not enough room for fingers in that little space in the truck. Didn't have to make any adjustments, and really appreciated that they included the correct adapter plugs as a set. 125177

No one would ever accuse me of being a handyman. I know which end of the screwdriver to hold, but that's about it.

Great product! I've used this same product for years and its always performed well with no problems! The reason I just bought a new unit is I just traded in my old Jeep and decided to leave the other one with the car. The new Prodigy 2 is now installed in my new Jeep and it is ready to tow! 75166

The brake controller works well and I installed it myself. I wouldn't have attempted it without the video instruction. Although the video for the honda odyssey has the guy mis-speak about hooking up the power wires backwards. I knew enough about it to know though, so not a big deal. 9821
