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 P3 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 P3 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 13 percent or 25 percent of the predetermined power setting.

So, if you boost the initial power so that your trailer brakes activate with 25 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 GVWB113%
Equal to tow vehicle GVWB1 or B213% or 25%
Up to 25% more than tow vehicle GVWB2 or B3*25%
Up to 40% more than tow vehicle GVWB3*25%

*Both B2 and B3 offer a 25-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.

Storable Settings

Customize your P3 and store settings so that you can easily access them later. If you tow multiple trailers, or the same one but with differing loads, store the desired boost and power levels for each so that you don't have to completely reset the controller every time you switch between the trailers. Do other drivers use your towing setup? Customize the P3 display with your desired screen color, brightness and language, and you can easily return it to your preferred settings the next time you tow.

Customizable LCD Display and Advanced Diagnostics

The P3's LCD display features a distinctive look with multiple color and contrast options. It also includes a highly advanced, easy-to-understand roadside diagnostics display. The P3 advanced diagnostics not only notify you of potential problems, but they can also tell you where to begin troubleshooting.

Safety Features

The Prodigy P3 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 P3 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 P3'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.

Automatic Leveling and Simple Installation

The self-leveling feature of the P3 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 P3 mounting360-Degree P3 mounting

Note: The P3 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.

P3 mounted in bracket P3 mount

Installation is a snap. After mounting the P3 unit in your cab using the included bracket, hardwire one end of the included pigtail harness directly into your vehicle. The other end plugs into the brake controller. To transfer the P3 to another vehicle or to remove it for storage, just unplug the unit and slide it out of the bracket.

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

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.

Installation of Tekonsha Brake Controller Adapter

Junction BoxBrake-Control Adapter Port

This adapter plugs into the port that is built into the electric junction box beneath your vehicle's dash. The black box is located to the left of the steering column, just above the carpet. To plug in the adapter, first remove the cover on the box. The adapter plugs into the second slot from the left, on the top row.

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.

After tiring of jerking, over reacting brakes from my trailer, or delayed almost no brakes (there was no in between) from my old 90's era Tekonsha Voyager XL (that has served me well through three trucks...until this last year), I finally decided to upgrade. What a difference! The P3 is silky smooth. I took it for a test run pulling a 8x21 enclosed trailer (empty at 3800#), 2 brake axles. Was easy to dial in. I started at a much lower setting then the instructions say. I never set my brake controller by "if the trailer tires slide, reduce power" meathod. I just paid $500.00 for good trailer tires (not china bombs) and I'm not fond of locking them up on pavement. So, i started low and worked my way up until I liked the braking action. Display is easy to read, day and night, even with my 53 year old eyes. It does concern me to see several pictures and one install video of the controller mounted below the dash. Very difficult to reach the overide without compromising your driving position and view of the road. Maybe it's just from towing with a controller with heavy loads for so many years...when you need to grab that overide there is a good chance its because there is a 'situation'. I'm right handed so mine is mounted just above my right knee. I only have to extend my arm to reach the overide. In fact, I make a habit of occasionally using the overide just to make sure I know how it feels...in an emergency, I don't want any other surprises. lol. I absolutely love etrailer.com...the best customer service on the web, good prices and great products. 565827

The Tekonsha Prodigy P3 brake controller installed very easily in my 2010 Tundra with factory towing package. I purchased the plug-in wiring adapter for quicker installation. This controller is very easy to set up with the preinstalled settings and very little fine tuning. 564856

I haven't used a lot of other brake controllers but I wanted to buy one that was easy enough to use and intelligent enough to where my girlfriend and/or mother could operate it and not have any sort of stopping issues (both have next to zero experience towing a trailer). From the small amount I've gone out and tested this, it works absolutely awesome and is very easily adjustable. I took my 26' enclosed trailer out with my 3800 lb car inside and the truck stopped almost exactly the same as with no trailer at all. My favorite parts are the fact that I can easily adjust the boost settings by clicking a single button and that it can distinguish between a gradual stop and a panic stop and adjust trailer braking force accordingly within a fraction of a second. Got cut off quite a few times like is normal in Chicago traffic and was able to hit the brakes and KNOW that everything was going to stop when I needed it to. Worth the extra money in my opinion to have a controller that I know is going to work great every time and that anyone in my family could operate correctly if needed. The built-in fault detection system is great also, no guessing if your trailer brakes are hooked up or working correctly, if it detects an issue at any point, it tells you right away. 154701

I ordered the Tekonsha P3 for my 2016 VW Touareg TDI. etrailer had a really great video about how to install it. It was a little difficult finding the electrical connection under the dash. The plug for the harness was under some grey foam rubber. I was ready to give up until I felt something that may be a plug under the foam. I scratched and tore the foam until I tore a hole in it. I then found the connector under the foam. This is all done working blind with one hand. I had already purchased the wiring harness coupler wires and parts from the VW Dealership Parts Department. When the Tekonsha P3 arrived, I assembled the harness with the dealer parts (wires and connector plug) and the electrical connector that came with the P3. I triple checked my work when building the connector harness. I covered the wires with some protective wire wrap after securing all connections with electrical tape and cable ties. My wiring harness was great looking. I had to reach under the dash, working blind, and I connected the harness to the plug under the dash. I had lubricated the plug with a small amount of synthetic grease. I had to work with one hand. There was not anything behind the connector plug to push against. So, I made a tool with a small piece of wood. I put the wood behind the plug and this gave me something to push against. I was elated when I felt and heard the coupler plug snap into place. I installed the new brake controller bracket and brake controller. The result was no power at all to the brake contoller. I took the Tourareg to the Dealership with instructions to program the computer for towing. Keep in mind the Dealership does not install brake controllers. The technician did a great job. However, he told me that I may have assembled the wiring harness wrong. I said I would go and check it out. When I hooked up the trailer and P3 brake controller, it all worked fine. I had power to the brake contoller. I programmed the Tekonsha P3 with my settings into the P3's memory. The P3 has a nice electronic display. The Tekonsha P3 works great for towing. All trailer lights work and there is 12 volt power charging the trailer house batteries. I did a test drive and I noticed nice even braking on the trailer brakes. So, I am happy with the Tekonsha P3. It works great on the 2016 VW Touareg. I am starting to think you may be on your own when it comes to brake controller installation. The dealership may have to program the tow vehicles computer. In my case, the computer had to be programmed. I was provided a loaner car and there was no charge for programming the computer. Thank you Volkswagen. 541827

Bought a Rockwood A122 camper that I pull with a 2018 Toyota Tacoma (I previously had a 2017 Tacoma). Bought the Prodigy P3 after doing a bunch of research online. When it showed up I was kind of blown away with how easy it was to install. The Tacoma has a Trailer Brake connector stuffed up under the left foot kick panel. Popped the panel off, found the connector and hooked it up. That's it! Then zipped two screws in the mount on the lower lip of the dash which no one will ever see even if the brake controller gets removed. Took me a little fiddling around to get it set for the right amount of braking that suited me but I have yet to touch the thing or mess with it since installing it. It just WORKS. It's small, unobtrusive (if you mount it in the right place) and it just works day in and day out with a minimum of interaction. Get one of these. 574016

Been a year. Still feel the same way as in my original review.

I have not connected the Brake Controller yet, but all I can say It was very easy to order. The price of the unit beat all other companies that was selling the exact model. The free shipping helped also. I thought it would take a week for the controller to arrive, but it was on my door step in two days with regular shipping. etrailer is a GREAT company for their products. Before I look at any other company for an item, I check with Etrailer first. I am getting ready to place a order with them now for an additional item. Etrailer, YOU GUYS ROCK!! Thank you for the great service! It has been a long time since I have been able to say that about a company!! 440018

The brake controller was installed and worked exactly the way it was described. The controller installation was very simple after reviewing the video for the product. In my opinion the video is a big plus in purchasing items from etrailer. Once again, keep up the GREAT work and customer service and I will always be back and refer all your products to family and friends!! Thank You Again!!

I purchased the Tekonsha P3 proportional brake controller and the Plug-in Wiring adaptor for my Dodge Ram Diesel 2005. It shipped promptly and arrived on schedule. I plugged it into the under-dash socket in about 30 seconds and tried it out before installing it; it powered up immediately and everything looked good. It took a few minutes to install the P3 bracket to the dashboard just to right of the steering column and about the level of my knee. The adaptor has enough length to put it left or right of the steering column, but not very high on the dash. The adaptor made the installation quite simple – gathering the tools and deciding controller placement took 20 minutes out of the total 30 minute installation time. The actual installation was to drill 2 holes and screw in 2 screws to the dash and 2 screws to the pocket bracket, then tying the cord to other wiring behind the dash. Settings for electric brakes and other info into the unit took under 2 minutes. Wow! What a difference - the braking was strong, smooth and uniform. I can only compare on my vehicle to braking without a controller unit engaging the trailer brakes, but it showed me how important those brakes are to an easy and safe stop. I have driven other people’s trucks with loaded horse trailers, and their controller units did not give anything like the constant readout of trailer brake voltage and other information this one gives you. This is obviously a high quality unit with everything I need and more. My priority is horse safety on the road and that includes smooth, proportional braking. I like the ability to monitor the voltage of the vehicle system, the volts and amps to the trailer, and troubleshooting capabilities. I spent 6 or 8 hours reading everything on brake controllers before ordering this one, and compared it to several other highly-rated units. While it is available for similar pricing from eBay and other sites, I found etrailer.com's website to make things very easy, such as finding the exact Plug-in Adaptor for my vehicle, finding videos about various controllers, and finding instructions for installing the unit. Thanks to the etrailer.com website, I was able to check under my dash to verify the brake controller plug was there waiting to be used, and I had a very realistic idea of the installation procedure in advance. Getting the Plug Adaptor in the same shipment was important too, and let me install it immediately. I was glad I ordered from etrailer.com and would not hesitate to order from them again. 164083

The Tekonsha P-3 was reasonably easy to install, and works like a champ. I had to spend a bit of extra time fishing wires because my truck didn't come with factory tow package wiring, but even then it wasn't hard, just time-consuming to route the wires where they won't get chafed. The controller comes with a nifty click-in mount, but I just used the U-bracket (also included) because I have no need to move it between vehicles. It's nice to have the choice of how to mount it. The instructions were very clear and easy to follow, even for a non-plug-in installation. It took me a little while to get it adjusted so that the trailer brakes didn't lock up on hard stops, but once I got it there, it's great - no more feeling like my trailer is going to push the truck through the intersection when I stop. It's easy to adjust for different trailer weights. It's almost too easy to adjust, in fact: I'll have to keep an eye on it to make sure I don't accidentally hit the "boost" button, which is designed for heavier trailers - I wish there were some way to disable the boost feature from the menus. Overall I'm delighted with the P-3. I like the text interface instead of cryptic numbers that so many units use, and I love the way it performs. 49045

Hi, I got my Item: 90195 and shipping was fast. I was able to get the break controller installed in my 2012 Cadillac Escalade Luxury using the etrailer.com video guide for a 2009 Cadillac Escalade. The install and wiring was the exact same as the video however my wires under the dash or wire bundle did not have a wiring sticker. The color of the wires were the same as in the video. This etrailer video is great and I used it to get my controller installed in about 1.5 hours. My install was trouble free. This weekend I was able to test out the my new P3 90195 controller and get it calibrated with my 29 foot travel trailer this weekend. Used a B2 setting with 8.0 power. The user guide and instructions you get with the controller help you know what settings to use and how to set the power level. This is my second controller as I got a P2 Tekonsha from etrailer about 4-5 years back and installed it in a 2007 trail blazer. This older 2P break controller is still working great. I have been rather happy with the quality of the Tekonsha controllers I have. I have not had to call etrailer for support or install questions but did receive a few emails from them to check in with me to ensure I got my shipment and offer me help. They do a good job supporting and responding to their customers and provide an A+ customer experience. 305014

All good on my end. The controller is working with no issue. Getting ready for our 6th camping trip this year. Thanks for your follow-up.

Installed P3 this weekend in 2013 Tundra Crewmax with towing package and pre-wire. Extremely easy, even with the center console installation. Will let the photos tell the story. Did have to combine the P3 included harness with the additional OEM harness to gain the length I needed. Plug and play with the pre-wire. Hooked up to trailer and set boost levels for varying loads. Works great! Vast improvement over older model Tekonsha controller in my Ram 2500 Diesel. Pull a Kiefer BP horse trailer: about 3600 lbs empty, 7500 with 3 quarter horses and gear. Usually pull 6-8 times per year, with only 1-2 horses. Short distance and flat terrain. It took about an hour to install. Dad is a retired USAF/FAA radar technician with every tool known to man. He QC'd the job. Will try to write better review later. 96005

how hard is it to remove small center console plugin great installation thanks Mark
-- comment by: mark d - 11/14/2013

To remove the small center console cubby hole you need to open both 12V outlets, then using your thumb and index finger, slowly work the cubby out. I used a very thin straight edge screwdriver to get it started as well. Helps to have two people. Once out, I used a rotozip tool to cut the back out. I thought I could get away with simply drilling a hole for the wires, but you will need more room. Recommend leaving a lip on the bottom edge where you cut out so small items dont fall behind your dash. Hope this helps.

Great write up Chris M. I just mounted mine and would like to make one note about the little yellow clips that hold in the console. They are very good at making a quick exit to some unknown location but I was able to fine the Toyota part number incase someone may need it. It is 90467-10203. They cost about a dollar. I got lucky and finally found the one I lost and saved myself a dollar.

Seems to work good, but the trailer brakes could not be adjusted to lock up no matter how high I adjusted the settings on the controller. According to the owners manual it should be able to lock up. Could it possibly be defective? Any help would be appreciated. Thanks 575180

The first thing youll want to check is that the brakes are properly adjusted. Jack up the trailer and use a brake adjusting tool to run the star wheel on the adjuster down until the wheel cant be turned by hand. Then, back it off by about 10 notches of the star wheel, or until theres only a very slight brake drag. If the brakes are properly adjusted, use a voltmeter to test the wiring at each brake magnet while a helper activates the manual override on the brake controller. You should see about 10-12 volts, but NO LESS than 10 volts. If youre seeing less than 10 volts, check the connector on the trailer and on the vehicle, making sure nothing is damaged or corroded. Trace the brake feed wire from the trailer connector back to the brake magnets, making sure that all connections are secure and that the grounds are connected to clean, bare metal. Examine the brake magnets themselves, as well. If the face of the magnet is excessively grooved or worn to the point where the copper wiring in the magnet is visible, the braking effectiveness will be greatly reduced and replacing the magnet would be recommended. Its usually recommended to replace the drum and magnet at the same time, if the armature surface of the drum shows any wear.

Bought a new Primus IQ brake controller but it only came with a pigtail wiring that had to be spliced into my '01 Suburban. Ordered the direct fit wiring pigtail from etrailer.com and couldn't be more pleased! It literally took me less than 10 minutes to plug in the wiring and mount the brake controller. Excellent customer service and very fast shipping! The kind of shopping experience that causes repeat business. Thank you etrailer.com and customer rep Lexus for making everything so simple! 203301

Excellent. No problems at all!

I installed this on a 2018 Subaru Outback. On my model the pale green wire was the brake stop light wire. The install was a little daunting but with patience and time it can be done, don’t give up!! One important thing to note is that THE READOUT ON THE BRAKE CONTROLLER WILL SHOW A NUMERIC OUTPUT WHEN YOU PRESS THE BRAKE IF INSTALLED CORRECTLY. Of course you need to have the trailer plugged in first. If you are driving and testing after the install and you don't get a power readout when you press the brakes you may have a problem with your brake stop light splice. That’s where my problem was. I had to buy some additional wire splicers because the ones provided were too big. Two very important things to remember. If installed correctly go put your ear by the wheels with brakes (on the trailer) and get someone to pull the manual brake lever. You should hear a hum sound. That means it’s working. Remember, if you’re in a bind and you need to use your trailer and your brake pedal isn’t activating the electric brakes but the manual brake is. You can use your manual brake instead. But don’t do this long term, I’m sure it’s not good for it. This is just some advice in the install. Otherwise it’s been a great brake controller! 530029

George J, Wanted to write good points about your customer service and the Tekonska braking system. Included are multiple pictures of the unit installed on my VW SUV. First off, I am not an expert in any way in installing and wiring. I had the good fortune of having Steve Kunzel, master mechanic at Westside VW in Minneapolis install the unit.(see Fig 1) The first unit sent did not function and was quickly replaced by etrailer.com at no charge. Second unit is pictured (fig 2) and works well. The trailer is used for caring dogs and gear to various dog events and hunting. The trailer weight is about 4500 pounds and the electronic braking system is necessary for good control of the SUV and trailer when braking. Thanks for all your help getting me up and running. 289246

Still works well.

I bought this for my Chevy Silverado 1500. For the most part, its pretty good. I tow pretty often but I don't use the brake controller much -- usually I'm towing things that don't need it. But, I have it, and its ready for when I do need it. The good: * Its nice and featureful and has a very top-of-the-line feel to it. * Its easy to read, easy to use. * Very easy to unplug or completely detach from the car when you just want to store it -- this is a big plus for someone like me who isn't using it every day. The bad: * It came with 2 different frames; one billed as "permanent" and one billed as "portable" (i.e. easily removable). The permanent one wouldn't fit right in the space I had (wasn't the fault of the device), so I had to use the portable one. The permanent one is the one that's a big metal frame, and the portable one is the smaller frame + the plastic piece that looks kinda like a spider attacking the device. The portable mount is actually pretty flimsy and it is really hard to get the device in and out of it. Once you pull it out of the mount, it doesn't really want to go back in. So I just leave my device in all the time, and unplug it when I'm not using it. Fortunately, its really easy to plug and unplug from the electrical system, which is what I cared about. * Installation was confusing. This is my 1 year follow-up review so, unfortunately, I don't remember exactly why I was confused ... There was 1 wire that was really unclear where it connected. My Chevy wires were labeled a certain way and the device's manual described the wiring using very different language. I ultimately matched wire gauges to figure out which one goes where and that worked out for me. But there was an extended period of head-scratching where I was trying to figure out the wiring. Ultimately, it's a good device, but if the portable mount was a little easier to use I'd give it a 5 star. Because its kind of shoddy in that respect, I've got to mark it down a star. 358859

Prodigy P3 brake controller was a very easy install with the help of etrailer video for 2007 chevy silverado new body style. Melissa W. was a big help with ordering everything I needed for the install. She knew what she was talking about. She was huge help before, during and after the purchase. She followed up with emails to confirm my order arrival and sent me other information about the install that I didnt even ask for. Great customer service so far! Thanks Melissa! Seems like a well built product. I will follow up with a review once I get to use it with my new trailer. So very glad I pruchased this model from etrailer.com. I went to the trailer store down the road from me and the same model would have cost me $40 more. Good job etrailer and Melissa W. 5 stars so far! 574141

Writing my one year follow-up review on my Tekonsha Prodigy 3. Well so far so good, works just like day one. I have it installed on my 2012 Toyota Tundra hauling a 28' travel trailer and it does an awesome job. I actually recommended this to my neighbor right before he was going to buy another brand without the manual brake override lever and he thanks me very time he gets back from a trip. I don't use it as often but I've been towing for a while and this is his first trailer so he feels safer using it, I know I do. So if you ask me I do recommend getting this brake controller. Easy installation and adjust to your braking power. Has lots of features and makes you customize your braking power. I also like the case it comes with to protect it when not in use. That's basically all I have for this controller. 565952
