Install your electric brake controller quickly and easily with this custom wiring adapter. Simply plug one end of the adapter into your brake controller and then plug the other end into the built-in harness beneath your 's dash.
Features:
Note: To illuminate your vehicle and trailer brake lights when you activate the manual override on your brake controller, use in conjunction with the Tekonsha brake controller converter with 7-way adapter (30235-P - sold separately). Required for use in the state of California.
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.

Install your electric brake controller quickly and easily with this custom wiring adapter. Simply plug one end of the adapter into your brake controller and then plug the other end into the built-in harness beneath your vehicle's dash.Installed in my 2020 Gladiator and used the 3024P adapter(you must switch the black and blue wires!) it works perfect. Yes i cut a hole in my new truck but it is out of the way and you can easily access it.
Shipping was timely product was excellent.
I purchased a new 2017 Ram 1500 and was looking for a break controller. My son recommended the Tekonsha Prodigy 2 . I found it on etrailer.com at a better than expected price and ordered the controller and the wiring harness. I received the item in four days. It was a breeze to install. Truly plug -and-play ! Set up was a snap and I like not having to level the device every time , as with my previous controller !
I am very satisfied with my purchase and with etrailer.com !
Just wanted to throw it out there for reference for any future searches. This was for installation on a 2020 RAM 1500 (DT) which did not have a factory tow package or brake controller installed. I reviewed the e-trailer installation video on a previous Gen RAM and it said the plugs would be right above the gas pedal. At first, I couldn’t find the OEM harness plugs; There weren't any plugs just hanging out in that area.
When I got my package yesterday, I decided to take another looksee.
This time I easily found it. Looking from under, I could see the two plugs snuggly taped together with black material, not electrical, tape. Looking up from my under dash position they were slightly to the left and up. If you have huge hands and forearms, it may take some positioning, and skin cuts, to get to. Luckily I don’t, but took a little finesse to get the tape off. Once I got that off, there was plenty of room to work and plug my adapter harness into.
The brake controller came with a mounting bracket and sheet screws to mount somewhere. Under our dash, there’s a metal dash screw right about the gas pedal that works perfect to mount the bracket. I put on a zip tie as well to make sure it was extra secure. Zip tied the extra slack of the OEM harness and adapter harness under the dash.
Very easy install.
Great product clipped straight into factory wiring harness. Ram 1500 Classic Tradesmen 2019

No problems excellent product
2015 ram 3500 truck.took all of like 10 min. To install and that's just taking my time.the 4 pin plug for the truck is just above gas petal.plug in the adapter to the truck.route the wires how you wish to run them.mount the controller where you wish to mount it which i utilized the panel screw for mine rather than put a hole in my new truck.plug in to controler zip tie the wires and your done.I read forums where people make a big issue out of this.truth is it's nothing to it.plug and go.hope my pics are helpful one showing the 4 pin plug,the mount location, and wires zip tied up.I like the mount type for the primus iq. Wouldn't be no problem swap g it to a different truck.I have not used it towing yet to review that part.maybe I can later
The wiring adapter plugged right into my truck I didn't time myself but it didn't take me but 10 minutes or so to install the brake adapter
Product was exactly what I needed. I sold my old truck with the wire still in it (different make) all I needed a new one for this truck. 5 min of searching and I knew I found the one. 2 day shipping and it arrived on my doorstep. After 10 min of pulling at wires and tape behind my dash I found the right ones. Plugged it in and wham it connected right away (only to tell me I had a broken wire on my trailer brakes, but that's another story).
Good product, fast shipping, A+
Etrailer was very responsive to questions and getting the right parts. Only problem was delivery timing and that was usps. Install was no problem.
The controller was extremely easy to install. Great product, plug and play
easy install took longer to get tools out than to put in definitely plug and play with wiring adapter
Plug and play. Gotta love it! My 2017 Ram 1500 didnt come with a factory brake controller and I didnt want to spend a lung buying it and having it put in. I found a Primus iq second hand on the cheap and needed the wire harness to make it work. Installation was a breeze and it looks and works great. I saved big $$ and am very happy. Lori B made it happen for me. She was very nice and gave me her direct line when I needed to call back and had the wiring sent out asap. Very satisfied. Thanks Lori B!!
This wiring adapter make it so easy to hook up my brake controller. I took my old brake controller (Primus IQ) out of my old truck which had to be hard wired and installed it on my 2019 Ram 1500. It was so easy, just plug and go, worth every penny.

Wiring adapter worked perfect
Easy install with matching wire harness for your vehicle. This controller with proportional braking is a lot of tech for the money and can be programmed easily in a few minutes for your trailer applications. I installed this on my 2019 Ram 1500 Laramie in 1/2 hour, most of that time was figuring out where I wanted to mount the unit. Works flawlessly, and can be be removed from the bracket in a minute and stored in the glove box (if you use the plug in wire harness to match your vehicle. This is a much better controller and several hundred dollars less than a dealer installed controller.

This wiring harness was a perfect plug and play for my 2019 Ram. Worked flawlessly, minutes to install.
I love that someone has a head on their shoulders to make the adapter to awesomeness and trailer hauling glory
The controller came with everything I needed, and it was basicly plug and go. I did have to install the box, but no problems. The frame had places , so I took two screws loose and simply put them through the controller frame and into the place below the steering wheel where they came from.Good to go.
Install was simple with provided factory match jumper. Total 10 mins to install on 2015 Ram 1500. Still need to configure settings otherwise purchase and install simple along with great price.

perfect
I've been very satisfied with this. No problems at all. Recommend
This morning's project, etrailer.com, delivered in three days, perfect fit, one recommendation, secure the hitch with the two factory bolts on each side, then fish the remaining four bolts into place
This is on a 2015 ram outdoors man  install was about 10 min.  very simple!!!!!  truck pigtail is right above right foot covered in a foam tape next to what i think is the factory brake control harness.  Thank You E-Trailer!!!!!!!
Easy to install. On a Dodge Ram truck the cable you need to connect to is hidden away under the center part of the dashboard, and you will suffer confusion, disbelief, and the betrayal of your helper until you fall triumphant and bloodied upon the floor of your shop (or driveway, no judgement..) with your prize in hand.
If it helps.. imagine yourself to be the automotive Indiana Jones.
After that, click the adapter cable into your controller and drive a test run with your trailer. Circle the block a few times screaming like a Viking who just survived his first time out with a raiding party.
Easy to install and worked great
This made the install very easy. I was able to toss the wiring parts that came with the brake controller and just plug this in on both ends and go on with my day. Picking where I wanted to mount the controller took longer than installing it
This harness was delivered in a large box with other items. The part itself was in a padded Manila envelope that looked as if it had been delivered by Ace Ventura. The wiring was damaged, which needed to be repaired before use. Unfortunately, I needed to use the harness that day and didn’t have the time to send it back for an exchange.

Thank you for bringing that to our attention! Customer Service should be reaching out to you in the near future.
Part was an exact fit....Have yet to have any problems any time I order trailer parts from your company.
With the special plug in connector for my Ram truck, hook up and instillation was easy and quick. Recommend the special adapter for whichever vehicle you want to install the brake controller
