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.

Speaker 1: Today we're taking a look at the Tekonsha Custom Wiring Adapter for trailer brake controllers. This plug-in wiring adapter allows for quick, simple installation of your electric trailer brake controller. There's no cutting or splicing required. You have the custom connector end that plugs into the built-in port beneath the dash of your vehicle. The other end plugs into the back of your electric brake controller. This is compatible with time-delayed and proportional brake controllers from TrailerMate, Draw-Tite, and Tekonsha.Just keep in mind that your brake controller must have a built-in plug for the adapter to connect.
This will not work on controllers with pigtail wiring harnesses. The wires also have a really nice mesh jacket that goes around them. It keeps your wires protected and it keeps them grouped together. Then the white wire here that's kind of by itself, has a ring terminal attached to the end of it. This is going to be your ground wire.
That's going to do it for today's look at the Tekonsha Custom Wiring Adapter for trailer brake controllers.

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
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

Great
I purchased the Tekonsha Prodigy P2 for use in my 2016 Toyota Tacoma pickup. I also ordered the appropriate wiring harness and since the truck had the towing package the installation was a breeze. The biggest challenge was finding a mounting location that didn’t interfere with airbags, hood release, reset buttons, yet was still visible and within reach. I found a spot that barely met all the criteria just to the right of the hood release. Everything works as it should and I’m very happy with the controller. It seems to be a well built quality product. I ordered this over the phone and Vanessa at etrailer couldn’t have been more helpful and knowledgeable about some subtle differences in the available wiring harnesses. The product shipped for free and arrived in less than one week. 472255

Ashley was very helpful. I had used a Tekonsha brake controller on my 2013 Tacoma and when I upgraded to a 2018 Tacoma she was able to set me up with this new harness. Saved me a lot of headache! 714364
works well 713463
Good construction, works as advertised. Was able to attach the ground wire to one of the steel bolt studs used for the accelerator pedal. Made the job of installing the trailer brake a breeze. Worth every penny. 705841

I installed the harness and it installed as promised. Good experience over all. 696769
Great product and service. This item enabled me to just “plug in” my Prodigy P2 brake controller into my new Toyota Tacoma. It was less than a 10 minute job. Most of that time was spent looking for the plastic Toyota panel faster I dropped in my garage. 695744
Well built. Cable was long enough for a driver's side install but not passenger side. White ground wire was long enough to reach a common factory ground point on side behind kick plate. Good instructions. Took 10 minutes to install brake controller and this harness. Made the job very simple. 694677
It was great - works well! 694000

Was a perfect fit for the 2019 Toyota Tacoma. Coupled with the Tekonsha Prodigy P3 Controller, It almost seems as if it was made for this truck. The unit , with some minor trimming, fit the compartment on the left side next to the steering wheel. Ground wire attaches easily to available bolt/studs with 8mm nut. 683576

Thanks 656490
Simple plug -n- play! Hammer down and trailer on! 655348
Item as described, works as intended, and arrived early. I'd buy it again. I do wish the cable was a bit longer to allow more mounting options, like the center console. When I ordered I didn't really know how long I needed and likely missed details in the item specs. Maybe there's a pre-fab extension cable or a replacement dash panel to accommodate the controller within the length of the cable. 653787
I haven't installed the harness yet, but I believe it will make the install easier for the electronic brake control. 653196
