Install your electric trailer 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 port beneath your vehicle's dash.
Features:
To install your electric brake controller, you need to connect the wiring of the controller to your vehicle. Certain auto manufacturers offer pre-wired options, typically known as tow packages, wherein wiring is run for you from the dash to the trailer connector on the back of your vehicle. When this is done, a port is installed at your dash so that you can easily plug in a brake controller.
This adapter plugs into the connector behind your vehicle's dashboard. The exact location of the plug may vary depending on your year, make, and model of truck.
No hardwiring is required to install this adapter. After you plug it into the factory port, you simply plug the other end of the adapter directly into your electric trailer brake controller. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time to transfer it to another vehicle or securely stow it away.

Install your electric trailer 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 port beneath your vehicle's dash.Everything came in the package and the product came earlier than I expected. Installing it was fairly easy. However the only thing that proved difficult was Torquing the ball down on the hitch head which luckily [RV dealer] was good enough to do that for me. I am happy With the product and looking forward to using it. 765567
This product makes the installation of a brake controller so easy that almost anyone could do it. If your truck comes with the wiring from the brake pedal to the trailer hitch already installed and you have your brake controller, this is all you need. Plug both ends in and your trailering. 574839
This is the proper unit for a 2018 Tacoma. the hardest part is finding the Factory plug, which is located behind the drivers Kick plate. connect the Ground to the 10 mm bolt that all the Dash connections are made to in the same place. 490874
I bought this harness for my Toyota Tacoma 2018 because I installed breack controller Primius IQ and fit very Good. I’m so glad with the product, and etrailer is really fast to delivery. 655736
If you want to make hooking up a controller super easy...this is the way to do it! Get this harness, it'll save you time and a lot of frustration. This went to my 2017 Toyota Tacoma. Plugged it in and screwed down the white wire to ground. Super easy. Hooked up just fine and got trailer brakes as soon as it plugged in. I'd do it again if I ever need to. :) 566265
Made the hook up of the controller very easy. Thanks to Kim for all her help. 558564
Purchased this connector to use my existing brake controller in a new truck. Like the ease of installation; a fool proof, no brainer. 472791
Exactly what I needed to hook up the Tekonsha P3 brake controller! Plug & Play to my 2019 Toyota Taco! Wiring harness for Taco and Tekonsha P3 controller and now I’m good too go! 854345
As usual I order all my towing items from e-trailer,I bought a new 2020 tundra with the stock towing pkg,i had bought a nice P3 brake controller earlier but didnt put in my jeep grand cherokee.The P3 is way better than a stock factory toyota controller so i wanted to use the P3.I searched the web and of course the forums etc suggested e-trailer had a wiring harness to replace the factory controller.Easy to instal as its plug and play with a white ground wire and thats it,no splicing or figuring out what wires go where.Im sold on e-trailer and wont go to big box stores or [email protected]&%on for cheap stuff lol.Like they say,pay me now or pay me later. 848119
Always satisfied every time I buy something from etrailer 845457
Get this cable for a simple, plug-in installation. You’ll spend more time hunting for the junction already wired into the truck harness than installing your brake controller. And after installed, no worries on loosening wire connections or electrical tape wrap unraveling. 837556
Works as advertised and I couldn't ask for more. I'm not mechanically inclined nor am I good with tech so I had it installed on my Tacoma by the Toyota dealer. Then had it adjusted/calibrated by Oliver Travel Trailers in Tenn. when we picked up our trailer. It's been used for about 3500 miles and it is in perfect sync with our truck. Buy it. You won't be disappointed. 831079

Easy installation and easy to operate I use it on multiple trailers and works well on all of them thanks for suggesting this product to me 824510
It was super easy to install. Just plug and play... 824389
Great price and easy installation! 820770
Great product. Ordered a brake controller and was exactly as described. Installation directions were detailed, easy to follow and customer service was excellent! 815538
Product is great so far. nothing to say 807844
This made the installation super simple. If your Tacoma already has the 7 pin plug on the back, then you can use this to just plug in the brake controller with this. You have to pop of the plastic kick plate, but no tools are required and mine when on and off easy. Once I figured that out, the whole brake controller installation took about 15 minutes using this wiring harness. 800144
Works great! Easy install. Plugged right in to the factory plug. 799512
