Installation of Tekonsha Brake Controller Adapter

This adapter plugs into the 5-pin connector on your vehicle's built-in brake control wiring harness. The harness is located underneath the dash, to the left of the steering column, taped to another harness near the emergency brake pedal.

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 cutting or splicing of wires to install. It is designed to plug directly into your electric brake controller for the simplest installation possible. Because there is no hardwiring, installation is not permanent. You can unplug and remove your brake controller at any time and securely stow it away.

Average Customer Rating:  4.9 out of 5 stars   (130 Customer Reviews)

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 in your vehicle.


This was long enough to route across from the emergency brake to the center console. Grounded white wire to a bolt under the dash with a 10mm nut. Easy



This device continues to work well. No problems at all

2006 Chevrolet Silverado

After 1 year of flawless use I am very pleased with this wiring harness for my 2016 Toyota 4Runner. The installation was super simple and easy; plug and play. I would definitely purchase again for another vehicle.

2018 Toyota 4Runner

Plug and play! I've had the same brake controller on several vehicles...get the correct harnest for your vehicle and easy peezy! Advice: Plan on how you're going to route your wire harnest first before mounting brackets.


Easy to install works great


I haven't installed anything from my order just yet so i can't comment on the products just yet. I'm sure that these, like the others I've purchased over the years will do the job as advertised. This isn't my first time dealing with etrailer, so I'm not at all concerned with the job before me. Very few companies I've dealt with are as capable and competent as etrailer. Their customer service is second to none. Every employee I've spoken with has been well versed in the products as well as their uses and their installation. I highly recommend. Love these folks.



So well, Ive not given it a second thought.


Added this to my 4Runner to pull my motorcycle trailer. Easy to install works as expected. Very happy with product and etrailer, they will get my future business.

2007 Toyota FJ Cruiser

I have not installed the wiring harness yet but I found the connectors looks like it'll be a easy install a lot easier than a 2007 FJ cruiser installation.


Everything i needed! Works great and great time in shipping. Thanks again!

2016 Toyota 4Runner

The wiring for the Tekonsha proportional brake control fit my 2016 4 Runner perfectly. Plus the videos that etrailer has showing where the plug in is under the dash made finding it a cinch.
Thank you so much etrailer- Anthony, one of their staff even sent me the links for the wiring and the brake controller videos so I wouldn't have to hunt for them. Amazing staff- very helpful. Thank you so much.



Thanks for asking. It means a lot that your company cares about products and service. Ive been very impressed with your company and the information that you provide. The brake controller works very well and is a very good product. Ive been very pleased with it. We went on a long trip from South Carolina to Montana. On the way we stopped by Mount Rushmore. Were going up a steep grade almost 10. Coming down it was nice that I could adjust the controller For more brake power. Thank you so much

2016 Toyota 4Runner

Plugged in to 2016 4Runner TE and Tekonsha Voyager brake controller. Works great. Easy install. Be sure to connect white ground lug to a good metal grounded location. Simple to install and price is great.

I like them. Performed well. Thanks

2015 Toyota 4Runner

Worked fine for my 2015 4Runner. Installation of the wiring harness, especially the ground wire, a little difficult.


Quick delivery. Video for install made it super easy. Everything installed and ready to go in less than an hour. Haven't had a chance to tow with it yet, but did hook up trailer and it controlled as expected. Seems like a good economical solution. RV dealer wanted $300-400. This cost me right about $100 with controller + custom harness.


Install was easy thanks to the custom harness. Seems to work great with our new Intech Sol Dawn camper. No complaints!!


This OEM adapter made the Tekonsha brake controller installation a very simple process. Installed in about 2 minutes.



After a year still works perfectly!


Purchased Brake Controller and Wiring adapter. It was just as easy (or even easier) an installation than described. Dealer wanted about $150 to "wire" my brake installer. I noticed this product on-line and read reviews and decided to see if it really was what it said. It took my son around 10-15 minutes to get it mounted and ground. When plugged into trailer, it worked!!
When contacting Customer Service, I was very impressed.

Toyota 4Runner

I ordered this product from Etrailer ( 3041-P). It is made very well and the instructions for plugging it into my 4Runner were spot on. I needed to confirm of fit and availability and talked to there customer service Rep Christina. I was delivered to my house in just a day or two.



I would highly recommend this brake controller to anyone. Used it many times and is very easy to adjust based on weight of trailer being towed.

2018 Toyota 4Runner

The Prodigy P2 Trailer Brake Controller for 2018 Toyota TRD Off Road 4x4 4Runner
Easy to install
I pull 4800 pounds behind my 4Runner after a year no problems yet.
The price was right,
Easy to install.
Thank You


The usual "excellent customer service" and "fair product pricing" that has spoiled us with for years now...nothing to see...move

Patrick L.


Its working out perfect! usual, great customer service,, awesome products!

1997 Toyota 4Runner

Worked like a charm. Installed easily in 2014 4Runner & 1997 Chevy 2500. No problems, no hiccups, no glitches pulling a 7x20 12k flatbed. videos, specifically installation videos are very valuable and one reason I keep coming back to The folks where I bought the trailer said I made a great choice with this controller. I couldn't agree more.

2016 Toyota 4Runner

Installed on a 2016 SR5 4Runner. Plugged right in, white wire with pre-crimped terminal loop made it a snap. Super easy install.

Been a year, still working great.


Good unit, reliable. Display is hard to read and the form factor and mounting location results in a banged Knee from time to time. A longer wire harness would be good enabling a center console mount.

2018 Toyota 4Runner

Just bought the cable that seamlessly integrates the Prodigy P2 brake controller to the factory wiring on my 2018 Toyota 4 Runner. A perfect fit that makes installation a breeze. Got quick delivery from


Super easy and a direct plug-in to factory wiring.


the electric brake controller was exactly as advertised haven't been able to try it out yet but it took about 10 minutes to install it it's very easy just watch their video have your tools ready and do it


Everything I have ever ordered from etrailer is top notch and their customer service is as good as it gets. I had delivery problems with the post office and an actual person from etrailer tracked the package and got the hiccup worked out. Can’t say enough good things about them.
