## Overview

The Tekonsha Trailer Brake Controller Harness (model 3031-P) is a plug-and-play wiring adapter crafted from durable polycarbonate, designed specifically for select Toyota Tacoma and Tundra models. It enables quick, no-splice installation by connecting directly to brake controls with built-in wiring ports, delivering a clean, professional setup trusted by thousands of users.

## Description

Our 2-Plug units are designed for brake controls that have a wiring port built into the back of the unit. Simply plug the brake control end of the wiring harness into the back of the brake control and the vehicle end into the automobile's port. Brake controls that utilize the 2-plug style of wiring harness will be identified with the Plug & Play logo.

Review: Ease of installation! - Perfect fit, plug and play no wiring extra lines!
Review: This harness will indeed fit the 2020 Tacoma - Fits perfect once you find the electric brake harness installed from the factory behind the left foot kick panel. A lot install this harness after removing factory trim. I personally did not. I only removed the one plastic nut holding the kick plate in place. Once removed I could flex kick plate enough to get my hands on the harness. When installing make sure you hear a nice click to know both male and female plugs are secure. I did not want to cut into my dash so I made a little bracket out of a 3” corner angle(see pics) works great and very clear of legs or feet. Makes for a very clean wire install as well. if anyone is wondering the 3” angle is mounted on an existing factory 10mm bolt tucked up above the kickplate. Was not easy to get the M6 nut started or tightened but once done I love it. I used the Tekonsha prodigy 2 brake controller with this harness.

### ⭐⭐⭐⭐⭐ Installed with Tekonsa control in 2019 Taco
*by D***D on January 28, 2020*

I read several reviews in discussion forums about the right wiring adapter to use in a 2019 Tacoma (they no longer ship a pre-wired adapter with the towing package as they did a few years back) and was a bit worried about the additional ground wire connection that several forums say is essential for this installation, and that this adapter includes. This adapter with the additional ground wire, installed very easily. I was able to make a solid ground connection WITHOUT drilling holes, there was a handy existing bolt into the chassis close to the connector for the harness. I was able to get the install done with no drilling. Have used the controller on several short trips with a livestock trailer and all is working as it should.
