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.

2015 Jeep Wrangler
Installed this in my 2015 Jeep Wrangler Unlimited Sport. I thought that I would add some input on installation that would help others.
I found a way to route the power distribution wires in the frame of the Jeep that did not require the use of a fish tape. If you look at the frame just behind the rear tire you will see a hole in the face of the frame. Start pushing the wire bundle foreword. It will rise up and over the U shaped frame portion of the rear axle and then down along the passenger compartment area. About there, you will be running out of pushing stiffness. Look for the wire bundle to appear at a similar hole in the frame in that area. Grab it a and pull out approximately 4 feet and then push it right back in the same hole going foreword. This time you will look for the wire bundle to appear at again a similar hole just foreword of the driver compartment. Now is the time to grab it and start heading up to the engine compartment outside the frame. Do the same procedure for the wire going aft for the plug end of the installation. For the wires going through the firewall, Jeep has conveniently added a nice foam lined hole to route wires through. You will see this hole position in the attached photo with a green wire coming through. The plastic cover around the steering column pulls down from the top and hinges at the bottom. Remove the metal plate with two bolts to get to the brake switch. Twist and pull the brake switch out foreword and go for the brown stripped wire as your brake circuit. Do order the LONG frame bracket adapter for the switch plug at the rear. To drill the steel for the supplied plug bracket just takes too long. Now that you have it installed you will notice that the power will remain on the unit after you turn the key off. Don't sweat this as it will not stay on long. I doubt a few milliamps draw is going to kill your battery!

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

very nice controller, very smooth and you don't have to mount it flat!! e trailer is the best company i ever worked with. they have pics, video, email support(exellent) and just flat out make it easy for you to do it yourself instead of paying some dirt bag $300 to install at your local trailer shop. i also installed kit #ETBC7 and once agian it was awesome. COMPLETE with DETAILED directions. i'm not a mechanic or hack employee at local trailer shop....BUT dealing with etrailer and there parts made my install very easy and CLEAN!!!

Your products are awesome. Ive had zero issues with it and 5 of my friends purchased and installed the same set up in there trucks. Thanks again for the great products and excellent support.

by:
Easy install, saved like $1100.00 installing it myself verses having a Camper dealer install one.

So far have only pulled the camper 2 times but the break controller works as described.
by:
while driving so I mounted the controller on top of the dash. I leveled the bracket with a spacer and ran the harness by an access panel. I used about 70’ of the duplex wire due to running the cable to front and then back to the house batteries inside the coach.
The access panel made it easy to make the connections and run the wires through the firewall.
I mounted the 40 AMP and 30 AMP circuit breakers up front in the main fuse panel box. I drilled a hole through the box and firewall to run the wires from the brake controller to the breaker and to the blue wire for the tow connection at the back of the coach.
I ran the battery connections to my house batteries up front instead of using the engine batteries in the back.
I found the brake connection wire under the coach in front directly below the brake pedal.
I mounted the converter in a beam in the back with lots of zip ties

For ford ranger 2010 and perhaps other years:Be aware that the video contains the wrong instruction for the 2010 ranger. In wiring the brake light wire, the switch shown being tapped into gives reverse braking sensing, that is, it is 12 when the brake is not applied, but 0v when it is. I found elsewhere that the correct wire is the 2nd connection on the 5 pin plug that rides on the brake itself.This is no comment on the original video, which was excellent, and referred to the 2011 ranger model.

Wire colors can and do change often. We offer the colors that we find in our videos as a starting point, but even if you have a 2011, it is best to double check and make sure to positively identify the wire color first.

2002 Toyota Tundra
Used in conjunction with harness kit for my 2002 tundra, this year has no provisions for towing trailer with electric brakes.
The controler itself has proven itself nicely, with no issues with installation or use, adjust easily.
The mounting location I chose may have some slight interference issues with legs on taller people, but I have not had any @ 5'11". The truck is a midsized so room is more limited. I'm towing a tandem 14' trialer with 4 seat RZR, tracking and stopping is perfect, even under hard breaking.

The Prodigy 2 was the perfect choice to replace an old brake control. This device worked great electric/hydraulic braking on large 5th wheel RV.

Great!! smooth braking when I haul my tractor and other materials

I purchased the brake controller and wiring harness from you all and installed it watching the video on your website. I followed the instructions to an absolute T. Got everything ready and tested the product and got an SH error code for the blue brake wire shorting out. I pinned and measured resistance and everything was coming back fine (4+ ohms resistance). I then hooked a power prope to it to find the short along the frame and nothing. I had power from the female connector all the way up to the brake controller. After 4 hours of troubleshooting, I found that the female trailer connector was shorted internally. See the attached picture. The blue and green ring terminals inside of the female trailer connector were touching. Replaced the trailer connector and now all is well.

This is a greatest brake controller l have had. I had a 95 Dodge Dam an camper combination and pulled a tandem axcels and hurling a jeep and was constantly adjusting the controller. With the same load it work grate and came with the best instruction and on Youtube too. I am going to get a base and holder for my 2000 Jeep Cherokee. Just transfer the controler back and forth.

2018 Chevrolet Silverado
I recently bought a 2018 Chevy Silverado LTZ. It was equipped with a towing package but no brake controller. Not wanting to alter the interior of the truck too much, I called etrailer for advice. Robert S was very helpful. He suggested the Tekonsha Prodigy P2 brake controller and jumper wire that I was able to hide neatly under the dash using an existing screw. I have been very pleased with etrailer and their suggested product.

2013 Jeep Wrangler
Great Brake Controller, used it with the Universal Install Kit for Brake Controllers and No-Drill Mount Bracket, Short - 18140. It only took me 2.5hrs to have it fully installed in my Jeep Wrangler Unlimited 2013. Videos were great. Also having some 1/4in water tubing helped for phishing wire thru frame.
Wish I had watched the video a couple of times before buying and also purchased the extra wire to go from the battery to the brake controller, but had extra wire from another project that worked.
This brake controller works great as we tow a <3500lbs Travel Trailer with our Jeep.
Comes with a great card that helps with settings, keep it in the glove box for future reference.

Coupled with the ETBC7 Installation Kit, this Prodigy P2 Electronic Brake Controller was quick and easy to install and worked the first time. It was installed on a 2011 Ford Ranger after watching the installation video online. Wish I had the optional 18136 bracket as it would have made the installation a little easier but it went fine without it. I include a photo of my circuit breaker location which is a little easier to get to than the one in the video. Buy It!

2010 Dodge Nitro
I installed this model 90885 Prodigy P2 Brake Controller using the ETBC7 Brake Controller Wiring Kit on my 2007 Dodge Nitro. On a scale of 1 to 10, I consider myself about an 8 where it comes to automotive mechanical and electrical work. I also strive to get as close to perfection as possible. To do the job right, it did take some time and it did require paying close attention to the directions for both the wiring kit and the controller. However, the directions were "right on", and all the needed "goodies" to do the job were furnished. My hat is off to ETRAILER for the informative videos they provide and their customer service, which includes very quick shipments of their products.

Toyota Tundra
The Tekonsha trailer brake controller was fairly easy to install and has a user-friendly wiring diagram to follow. The unit performs well in the Toyota Tundra and on our new 17ft. Casita camper trailer. It does what it is supposed to do and functions well. I do agree with another comment that the bright blue light at night would be better if wired into dimmer switch.
by:
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.

2010 Ford F-150
Received the trailer brake in just a few days. I installed it in the slot where the factory brake would go. If you have the trailer tow package there is a wire harness below the steering wheel to plug into. I drilled a small hole in the end of the slot to put the wire harness through and used the red 3M tape to stick the brake bracket to the top of the slot so I didn't have to try to drill holes to mount it and I can slide it out of the bracket to remove it if I need to.
It works and looks great in my 2010 F-150
by:
2014 Jeep TJ
I purchased this controller for my 2005 Jeep TJ. We're towing a 2014 Forest River FLagstaff MAC and, after doing much research, we decided that this unit (along with the universal installation kit ETBC7) was the right one for us!

Both the controller and install kit contain everything that you'll need for a clean, professional-looking install! The install took around 2 hours (in my driveway) and the controller works flawlessly!

This setup is perfect for a Jeep TJ, the controller fits nicely to the lower left of the steering wheel (out of the way) and the trailer connection is a bolt-on setup that attached to my Reese towing hitch!

The trailer connection (with the install kit) has both a 4-pin connection and a 7-pin connection so there is no need for adapters! It is truly a "plug and play" setup!!

As far as ordering and customer service goes, this was one of the smoothest transactions I've had in quite some time! There are numerous photos and install videos that will guide you through the install.

We'll definitely start with etrailer.com for our next purchase like this!

Happy to have it! And saw was tricky. I wasn't quite comfortable cutting through the main wiring grommet through the firewall, so instead I used access through the hood release cable. Took some finagling! All in all it's working out so far. Had my first pop-up trailer pulled this weekend and the brakes worked well!

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

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

  • Electric Over Hydraulic Brakes Don't Work w/Brake Pedal on Newer GM Trucks w/OEM Brake Controller
    Like you said, many factory integrated brake controllers will not work well with electric over hydraulic trailer braking systems. Some of the newer versions of these controllers now have an electric over hydraulic mode. Check to see if any of your trucks have this mode and, if they do, if the braking starts working with the pedal. Otherwise there are a couple of solutions to solve this issue. First, there may be an adapter that will allow the factory controllers to work but it depends...

  • Parts Needed to Install 7-Way on 2022 GMC Savana without Tow Package
    Hey Joseph, since your 2022 GMC Van doesn't have the 7-way wiring that would indicate it doesn't have the factory tow package so you'd need to go a different route to install a 7-way. You'd need to first start with the 4-way kit part # 55540 that is a confirmed fit for your Van and then convert it to a 7-way with the part # 37185 if the trailer you plan to tow does not have brakes. If you have trailer brakes you need to operate you'd instead want the # ETBC7 with a brake controller like...

  • Brake Controller Recommendation for a Truck with Air Brakes and a Trailer with Electric Brakes
    The trailer brakes work on a separate circuit than the lights. You have a couple of options to control the electric brakes on the trailer. One option is to use an air over electric brake control, # HA100400C. This unit connects to the air brakes on the truck and when the brakes are applied it sends an electric signal back to the trailer brakes. The other option, and what I would do, is to use an electric brake controller like # 90885. For either of these controllers, the red wire attaches...

    To tow your trailer that uses an RV style 7-way blade style connector with your semi that has a 7-pin connector, you need to construct an adapter that will also combine the brake signal into the right and left directional signal pins. This can be done by using a female 7-pin socket # PK11720 to accept the plug from the semi, a tail light converter # 119178 and a female 7-way RV blade-style socket # PK12-707E. The converter would be wired in between both sockets to combine the brake light...

  • What Trailer Wiring is Needed for 2024 Subaru Outback Wagon
    Hey Ryan, so I looked up the Aliner LXE and it doesn't look like a trailer that would have brakes so most likely all you need is a 4-way confirmed as a fit for your 2024 Subaru Outback XT like the Tekonsha part # 118467 which installs pretty easily. 4-way trailer wiring basically controls all of the taillight functions on a trailer but nothing else If instead the trailer DOES have brakes you would need to convert the 4-way to a 7-way with the part # ETBC7 so that you can install a brake...

  • Troubleshooting Tekonsha Prodigy P2 Brake Controller that Doesnt Recognize Trailer
    It's possible the brake controller is bad, but you definitely want to check some other things before you purchase a replacement. The first thing to do is inspect both the truck's and the trailer's connectors to make sure the pins are clean and free of debris. On the trailer connector at the rear of your 2004 Chevrolet Silverado test the pin at the 5 O'clock position with a circuit test like # PTW2993. You'll need someone to engage the manual lever on your P2 for this. If this checks...

    Hey Bob! Your 2024 Entegra was built on a 2023 Ford F-53 chassis and depending on what package you have you may have a brake controller port or you may have a bundle of wires that are labeled and tucked away. Additionally, some of the ports don't come wired up and if this is the case it'll be easier to just splice into the bundle.

  • Brake Controller Has Constant 12V Power But Trailer Brakes Do Not Engage
    First I suggest you double check your wiring from the controller. Typical brake controller wiring is: Red wire goes to the brake switch cold terminal, which gets power only when the pedal is pressed; Blue wire connects to the trailer brake circuit; White wire is ground; Black wire connects to the 12V power source. Please note that we do offer vehicle-specific wiring harnesses that plug into the OEM socket under your dash and provide bare wires on the other end to wire directly to your controller....

  • Installing 7-way Blade Trailer Connector on 2013 Toyota Highlander
    To wire your 2013 Highlander with a 7-way and 4 pole connector, you'd first need a functional 4-pole trailer connector. If your Highlander doesn't already have one, you can install it using part # 118449. With the 4-pole in place, there's two different alternatives, depending on if your trailer with the 7-way has brakes. If it does NOT, you can use the Hopkins # 37185 (same as the 47185 you mentioned). The 37185 would plug directly into the 4-pole, with 4 remaining wires. The white wire...

  • Parts Needed to Install Trailer Brakes on a Load Rite Trailer Model UT6512
    Looks like your Load Rite trailer UT6512 has a 3,500 lb axle. Most likely it's a standard 3,500 lb trailer axle but first you have to check to see if the axle has brake mounting flanges. If you can get back to me with whether or not you have brake flanges and the brand of your axle (most likely Lippert or Dexter) I can see which kit we have that may work. Check out the link I attached to see a guide to use for adding brakes to your trailer.

  • How do I Tell if the Brake Controller is Bad
    You are correct, you should only be getting output when the brake is applied, or the override switch is activated. It sounds like the controller might be bad, but to make sure, you should probably bench test it before tossing it. Use a circuit tester, and check the red wire that exits the rear of the controller. This wire should only go hot when the brake pedal is pressed. If this checks out ok, then the controller is bad and must be replaced. We have a video that shows how to bench...

  • Parts Needed to Install Brake Controller in 2014 Honda Pilot
    Hey Mike, the 7-way kit part # 118265 does fit your 2014 Honda Pilot to provide it with a functional 7-way but it does not come with the brake controller install port you'd need for a brake controller. So you can hardwire in a brake controller or have a Honda dealer install one for you so that you could use a # 3070-P to install a brake controller like the P2 part # 90885.
