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:

  • Plug-in wiring adapter allows for quick, simple installation of your electric trailer brake controller
  • No cutting or splicing required
    • Custom connector end plugs into the built-in port beneath the dash of your vehicle
    • Other end plugs into the back of your electric brake controller
  • Compatible with time-delayed and proportional brake controllers from TrailerMate, Draw-Tite, and Tekonsha
    • Brake controller must have built-in plug for adapter to connect - will not work on controllers with pigtail wiring harnesses

Installation of Tekonsha Brake Controller Adapter

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.

Video Transcript for Tekonsha Brake Controller 3031-P Review

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.

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

Plugged right in to the factory harness without difficulty. The hardest part was locating and fishing out factory plug behind the kick plate. 463073

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 ordered the custom wiring adaptor to replace the wiring from my 2015 Tacoma to my 2017 Tacoma for my primus electric brake control. Because of the holidays the order took a little longer than usual witch was o.k. with me because I didn't need it until this coming summer. Christina J. helped me with my order and was very professional and knowledgeable about the product. This is not the first time that I ordered from etrailer and have never had a problem. 468823

2016 Toyota Tacoma

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

First, I want to confirm that this is the correct harness for a 2018 Toyota Tacoma. The dedicated ground wire is required, I believe, due to a fault with some e-brake units. Second, eTrailer was awesome. I accidentally ordered 3017-P (same harness without the ground wire), and customer support quickly cancelled that order and issued the correct 3031-P. Very happy. 548215

The cable fits the desired application on my 2018 Tacoma. A couple of inches longer would have been nice - it was barely long enough for where I mounted the controller. The location shown in the pic was the only location that didn't get in the way of of knees, feet or air bags. By the way, the other item in the cubby is my ham radio faceplate. 553371

I bought this adapter to prove that my factory brake controller was not functioning properly. I am now using my old Prodigy P2 controller I was using on my previous truck n trailer, bypassed the factory unit on my current truck. Needless to say, it worked perfectly. My factory controller would not engage the travel trailer brakes no matter how I adjusted it. The P2 works with electric and electro over hydraulic brake systems. My truck has a button to select. My problem is in electric mode. If I switched to elec over hyd, the brakes lock up. I am going to the dealer to have him check the factory control and hear what they have to say. 612831

Not quite a year ago I purchased a new 2017 Toyota Tacoma TRD Off Road. I believe all the Tacomas come stock with a trailering package, 2" receiver hitch and a wired standard flat 4 pin and 7 pin for those using electric trailer brakes. I had a Tekonsha brake controller installed and bought the wiring harness,Item #3031-P and it plugged directly into the factory wired harness provided by Toyota. A very straight forward easy installation in my case. 600777

Perfect! But when ordering this model harness for my Toyota Tacoma 2017 and newer it says to order this 3031-P. The box this harness comes in is deceiving as it shows it is for Toyota Tacoma 2016 All models. It's really for 2016 and newer years as well. It truly is a plug and play for the Tacoma's and some Tundras. Tundras will need to select vehicle year, make and model to verify. 591273

  • Location of Brake Controller Port Under Dash of 2015 Toyota Tundra with Factory Tow Package
  • The brake controller port for the 2015 Toyota Tundra is located behind the section of the dashboard with the tow/haul button. To reach the connector you will need to locate the notch in the access panel in the center of the dash near the driver's side. Using a trim panel puller like # ALL648544, carefully pry the panel out and undo the locking tabs to remove the panel. You will find the mating connector behind this portion of your dashboard.

This is our best selling brake controller because of how well it works and how easy it is to setup. This is a proportional brake controller that senses the amount of braking the tow vehicle is applying and applies a proportionate amount to the trailer brakes.
