Video Transcript for Choosing Between Tekonsha Brake Controllers
When it comes to choosing a brake controller, a lot of them are gonna look very much the same. And two of them that I really like are from Tekonsha. We have the Prodigy P2 and the Prodigy P3. So, they look very similar, but they do have quite a few differences and we're hoping to break that down, that way you can decide which one's best for you. Here we have our P3 installed and really it comes down to it has more bells and whistles than the P2, otherwise it's pretty much the same controller. The P3 does have a nicer/easier to use display.
It's a little bit more user friendly. It uses some icons here that, you know, show you a trailer and that way you know pretty quickly what boost level you're at and it's really easy to read. It's a nice digital display and you can change a lot of that. Also, it has a little bit more diagnostics. So as far as, instead of just having error code with the P2, this one will actually tell you exactly what it is and there's a host of diagnostics so that way you can look at it.
You won't have to troubleshoot the code by looking at the owner's manual. It'll tell you right away what's happening. The P3 is also really nice if you have a bunch of trailers in your fleet, you can set up presets, up to five of 'em, and that way when you hook up to said trailer, you can select that and it's gonna be preset to the boost settings and also the gain that you may have dialed in. That way you just hook up and you'll be ready to go. Multiple trailer settings are gonna be nice, especially if you have a work truck and you're hooking up to a bunch of different trailers, you can get that dialed in, but if you tow the same trailer over and over, or you know that you're only gonna have one trailer long term or maybe two, that's really not gonna be a function that is necessary.
Now with the P2 installed, you can see right away that the display is obviously not as fancy as the P3, but you again have all the same functionality. There are less buttons, so that kind of keeps it simple. If you just need a brake controller, this is a great option. You still have your power knob, you have your boost button, and you still have essentially the same manual override, which I do like on the Tekonshas, you have a nice modulation here. But really when it boils down to it, they are very, very similar.
The size is gonna be almost identical. They're gonna mount up the same, they're gonna install the same. Again, you have that same proportional here. They both work for one to four axles. They're both proportional. So pretty much the same thing, just more bells and whistles on the P3. If it's something that you're gonna wanna keep for a long time on your vehicle, a P3 is pretty sharp. I do like the display, and something to think about too, you can always take a brake controller from one vehicle to the next, so, but if you're just need to tow a trailer and you need a brake controller, P2 you're not gonna go wrong with. I just like the fact that there is diagnostics that are a little bit more straightforward with the P3. And if you're worried about if it's gonna work with your trailer, they're both gonna work with the same kinds of trailers. You can have electric brakes, you can have hydraulic brakes, it doesn't matter. These are gonna work with either one. So hopefully this video helps break down some of the similarities and differences to help you decide which Tekonsha Prodigy Brake Controller is gonna be best for your needs.

The P3 has been the best controller I have used. My two previous trucks had different and older Tekonsha controllers all pulling the same 1988 18' travel trailer. Neither really applied the trailer brakes as well as I would like. The P3 in my 2019 Ford Ranger pulling the same trailer made the brakes feel great. The ease of adjustability and feedback on the screen are such an improvement over just a series of lights. Installing is simple and if the tow vehicle has the tow package harness and plug under the dash it couldn't be easier. This controller is worth every penny!

I previously had a Bluetooth brake controller which cost more than this one but was a pain to work with since you had to link it to your phone and constantly adjust it, but this Tekonsha controller works like a charm and I have not had to adjust it once since installing it and setting it up the first time. I highly recommend it!

I'm glad that you like the P3 so much, John! I do have to agree with you on that, brake controllers like the P3 are better than the Bluetooth option. What kind of trailer(s) are you hauling with your truck?

Easy upgrade from my existing (timed) brake controller in my Jeep JKU for towing my popup. The only issue I had was when opening the box, I found the screen to be lightly scratched from shipping from the manufacturer. Joshua B. Was great in helping me come to a resolution on it. I haven't towed with it yet, but really pleased so far.

Piece of crap. Voltage sent to brakes is intermittent, especially at low speeds while in traffic at traffic lights. Sometimes the correct amount and other times too much causing a jerking motion. Also, the back up feature does not work. Called company and they sent me a replacement and it did the same thing. The P-2 model works fine. DO NOT buy the P-3.

I purchased and installed the P3 controller in a 2018 Toyota Highlander XLE after reading many great reviews about it. Wanted a hard wired controller vs. wireless because a brake controller is too important to run over an unreliable wireless connection. Having an IT background I know how unpredictable wireless connections can be. Installation was fairly easy, the hardest part was running a few wires through the firewall of the vehicle.
A few notes, the installation of the actual controller under the steering wheel area was a little difficult because of the design of the mounting bracket. This could be designed better for easier installation. Also, I got a pre-collision warning on my instrument cluster whenever the brake controller was activated. To fix this I had to solder a 1 amp diode on the red cable, which I protected with heat shrink. I reached out to tech support about this error and they were very helpful talking me through a solution.
I like the adjustment capabilities of the controller. I have been able to adjust it so the brakes don't grab when stopping slowly. I really like the manual slide for activating the brakes. This has been very useful for applying brakes on the trailer in a few critical braking moments. The manual lever is also very useful for checking the brakes after connecting the trailer to make sure they are working correctly. I also like that the display shows the level of braking that's applied to the trailer. The color of the back-lit display can also be adjusted to match the vehicle's displays. I definitely recommend this brake controller.

Still think this is a great brake controller after using it while traveling full time for about a year. I was able to change the sensitivity of the brake level to my liking after several trips, which is another great feature.

are the best, and the main reason I am the proud owner of Tekonsha P3 Brake Controller! (see, I initially had an issue with my standard online payment service and almost canceled my order because of it) So I went old school and picked up the phone, one with a cord and spoke to a human being. Her name is Janice, and she made me feel confident that I could trust her and etrailer. And as a result, 4 days after placing my order with her I received my package. That's incredible. I am very happy and will most certainly do business with etrailer again in the future because of Janice.
I don't have any experience with brake controllers. So I can't really comment on how much better or worse this one is to any others. But since I am new to the B/C scene maybe this can be considered an unbiased, non professional review of the Tekonsha P3.
My general skill level is "requires supervision around all power tools". But I do have some mechanical ability (snicker). So I will just say, if I could install this thing anyone should be able to do it. Of course I also bought the OEM wiring harness for my vehicle so even I was able to figure out which plug went where. On A scale of 1 to 10 I give it a 3 (I'm somewhat large and getting under the dash wasn't easy or it would be a 1). And as others have said, deciding where to mount it actually took longer.
I attached mine to the top of the lower dash cowl and it fits almost tight to the dash but still within the 180 degree limit. This positions the controller at the same height as my knee and puts it within fingertip reach while resting my hand on my knee. I can see the controller perfectly through the steering wheel spokes. I went with the green screen background. it seemed to provide the best view in all lighting conditions.
The controller itself works perfectly and the set-up was a breeze. Once installed all the functions worked as described. The real time vehicle diagnostics are a plus. I like being able to monitor my battery voltage to the decimal place if I want to. I'm sort of a techno geek so this is really cool. I set the B/C voltage per the instructions and will only use the boost feature if I am in a hurry or feel the trailer is at max load, but my truck is 8k lbs so you may want to set yours to suit your own conditions.
I highly recommend the Tekonsha P3 brake Controller if you want the latest and probably the best controller out there in this price range. I highly recommend the OEM wiring harness if your skills are not pit crew comprable and want the easiest install possible. And, I highly recommend you buy it from etrailer if you want to get it at the best price available (I checked them all) and want the added security you're buying from one of the best online retailers that sells this product. And do yourself a favor, go old school for a change, use the phone and call them, and ask for Janice, although I'm willing to bet everyone there is as nice as her.

controller mount since the X is limited in under dash metal but the install went well. The 7 pin trailer harness is a factory Nissan part (plug and play) , but since the receiver does not have the any mounting brackets, I positioned the 7 pin connector up and out of the way of harm by drilling and flush mounting it in the rear bumper. Thanks for carrying products relevant to your customer's needs and having products that work right. I have attached some pics from the finished install. I will be ordering accessories as I need them from your company as you have always been prompt, thorough and very courteous in all of your correspondence.

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.

how hard is it to remove small center console plugin great installation thanks Mark
Chris M.
11/26/2013
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.

This Tekonsha Prodigy P3 was recommended to be by a friend who works at an RV dealership service center. This is my fifth trailer brake controller over a forty-year period, and my first progressive controller. I really love this controller. My truck has a factory towing package, but was manufactured prior to inclusion of integrated controllers. Since the truck has factory towing, the installation was very simple. The installation instructions were clear and complete. I would definitely recommend this controller to anyone looking for a dependable, easy to install and easy to use controller.

I have a 2018 BMW X2 that did not come with a factory tow package. I had an etrailer hitch and 4 way plug installed last year and has been perfect since. I just recently purchased a camper and needed to have a Brake controller & Brake controller 7 way deluxe kit installed. My mechanic installed them with the detailed instructions that the units came with without any issues. The Tekonsha P3 is extremely user friendly and is working flawlessly. A bit overkill for my car being I can only tow max 3500 pounds, and my camper is 1 axel. this unit is rated up to 3 axles. I look at it like this way, when I trade in my BMW I will take my P3 with me. etrailer is amazing with the support & products they provide and I highly recommend them to anyone who asks me.

my 2011 Jeep Grand Cherokee and this was a great controller and the price from etrailer was very competitive with other sites. What ended-up being the deciding factor for me on where to purchase the controller was the ease-of-use of the etrailer site. They made it simple to find and compare controllers and getting the correct wiring harness for my application was easy.
In addition to the site they have outstanding customer service. The controller was shipped the day after I ordered it (on a Saturday no less) with free upgraded shipping. They even followed-up with me once the controller arrived at my house. I wish all sites had this level of customer service!

how did you get it in the cubby hole? did you need to drill any holes? is it difficult to remove the dash covers and council?
James E.
8/15/2014
OK, How did you get the shift lever off? I got the two screw out from the bottom of the storage bin, but it still will not come out. How did you get the upper trim with all the electronic buttons off? I will not drill a wire hole thru the bin without removing it for fear I may hit or damage something right behind the bin, or have the way blocked by something so I couldnt route the brake controller cable through the hole I just drilled. I cant get at the bin from the gas pedal area. In fact I cant even see it from there. Thanks.

I mounted my Tekonsha P3 on the dash just to the left of the steering wheel. Has very easy access to quickly activate the lever on the bottom of the unit to apply maximum trailer brakes. But I needed a wiring harness almost double the length of the Tekonsha Wiring Adapter so I just purchased two and spliced them together to make one long one......yea I could have saved money and just sliced in longer wires....Am very happy with the Tekonsha P3, With this mount it makes it easy to disconnect and put into my Ford F150 or my Tacoma.

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.

I have a small tow vehicle, an Aluma trailer and a Yamaha Rhino. I got the Tekonsha controller, trailer harness, brakes, breakaway kit, LED lights, spare tire bracket and a few other odds and ends from eTrailer. I did all the work myself using links provided by the eT staff and it came out great. I do not have a single complaint!

I drove my rig plus I added a small Yamaha trail bike. I went to the Colorado mountains and I alternated between gentle braking with the car and trailer and sometimes just manually braking the trailer to keep my downhill speed in check. Still no complaints. Of course, pulling an aluminum single axle trailer empty won’t get you stopped because the tires will just skid.

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.

First and foremost purchasing anything from ETRAILER is easy and fast. There is always someone following up on your purchase and if there is an issue it is quickly resolved. I purchased the Prodigy 3 brake controller along with the wiring kit for my 2017 Nissan Titan SV and installed it myself with the help of the tutorials on ETRAILERS website and it was very easy to do. I will continue to shop at ETRAILER.

Controller with the hiring harness installs in literally minutes. Took longer to find the screwdriver. I used the saved trailers feature to set up one with my rig empty, one loaded. With a bright orange screen for the loaded one. Off the scales last week with a load of gravel at 23,400 pounds. Controller works perfect and the truck stops. Having the options and features available on the P3 was worth the extra dollars and a great upgrade. Super easy to use and the customer service here is best ever.

2017 Toyota Tacoma sport with tow package installed P3 controller and wiring with the help of ESP truck accessories installation kit for P3 mount plate that replaces coin holder with no drilling of any kind pretty happy where it's located and no drilling involved it was a pretty fast install with easy to follow instructions
I would recommend anybody with a Toyota Tacoma 2016 to 2018 with this set up
The Toyota dealership didn't even know this existed with a P3 until after I showed him the photo

Wow! What a great controller! So easy to install and set up. Instructions are great. My electric trailer brakes had never been used, so had to be burnished in. The flexibility of boost and voltage adjustments on the P3, allowed me to quickly change the settings as the brakes wear in and had greater braking action. I highly recommend this controller!

10/10 does the job very well and was easy to install myself (be careful about airbags). Saved me a large custom job bill. Worth the price and functions perfectly.
I purchased with the connecting cord/plug for my vehicle and it was seriously the easiest thing to install. Two plugs ins, screwed into my lower dash and done.

One of the best on the market, installs in minutes and looks like it was meant to be there. Installed on a 2017 explorer sport and we use it regularly with a two axle camper. The colour change feature is nice and matches the ambient lighting in our vehicle( which we can also change colour).
Definitely a must have for towing regularly. Always choose proportionate brake control, they cost a bit more than time control but well worth the money.

Great brake controller! I installed this unit in my 2016 Ford F250 4x4 in just over 30 minutes. Of course, I spent a little time (about an hour or so) in advance on the etrailer website researching how to install this controller. After watching a few videos and reading a few detailed reviews I was ready to go. I did order a plastic trim removal tool set on [site] prior to this installation. ** NOTE to etrailer: Think about offering a set of trim removal tools for sale to your customers - very important!**. I figured the $25.00 spent on the trim removal tool set would ensure no damage to the interior of my new truck and I was right. This is my second or third brake controller purchased from etrailer. Fast shipping and great products! Thank you!!

- Difference Between Curt & Draw-Tite Trailer Hitches For 2018 Jeep Wrangler UnlimitedHi Ken, Starting with the wiring harness, I can verify for you the correct fit for the 2018 Jeep Wrangler Unlimited without a tow package is indeed the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118786. Then for the hitches, the biggest difference between the Curt Trailer Hitch Receiver # C13392 and Draw-Tite Trailer Hitch Receiver # DT78MR is the length of the receiver. The Draw-Tite has a shorter receiver that can make it a bit more of a pain to add a ball mount...

Some of the newer versions of these controllers now have an electric over hydraulic mode.

If there is corrosion in the trailer side connector, you would need to replace it with 7-way Connector, part # A7WCB. For the replacement vehicle side connector, you would need Adapter 4 Pole to 7 Pole, part # 30717.
