Video Transcript for Redarc Tow-Pro Trailer Brake Controller Plug-and-Play Wiring Harness Review

Brad Hello neighbors. It's Brad here at etrailer. And today we're taking a look at the vehicle-specific wiring harness, that will work in conjunction with the Tow-Pro Elite electric trailer brake controller. These harnesses are going to be great to work with your Tow-Pro Elite in a variety of different trucks and SUVs. Now, make sure that you get your vehicle-specific harness. You're going to want to use our fit guide on "", and that's going to make sure that you get the right harness, and that way your install goes nice and easy.

Included in the REDARC kit, you will find this plugin adapter, and this is going to have these spliced ends, and you're gonna have to tie into your brake signal, your brake output, your power output and your ground. Now, if you are pretty handy with electrical, that's awesome. That's great. You can use this. But I'm the kind of person, plug and play in OEM kind of setup or really nice factory one like this.

This is the vehicle-specific harness. So this ties in directly to our factory tow system, and clips right in, it's got this nice braided sheathing on it, to kind of protect the wires, and then it plugs directly into our module here. So, to save yourself a little bit of headache and time, and make the install go that much smoother, and not have to worry about loose connections, I highly recommend getting the vehicle-specific harness. So this end of the plug is specific to your vehicle. As you can tell, it looks like the factory plug, it fits in perfect, has the locking mechanism, so you aren't gonna have to worry about loose connections happening with your plug, and it's going to make install a lot easier.

And that was a look at the vehicle-specific harness for the Tow-Pro Elite electric trailer brake controller..

Plug-and-Play Wiring Harness for Redarc Tow-Pro Trailer Brake Controllers - RED99FR

Average Customer Rating:  4.9 out of 5 stars   (285 Customer Reviews)

Install your Redarc Tow-Pro electronic brake controller (sold separately) quickly and easily with this custom wiring adapter. Plug one end of the adapter into your Tow-Pro brake controller and plug the other end in beneath your vehicle's dash.


Perfect fit and function. A word to potential installers. On my vehicle, the white mating plug in the truck, that this harness plugs into, was buried and hidden in the vehicle wiring harness. It was there, but hard to find, on my truck anyhow.


If your vehicle has a factory towing package, ordering the vehicle specific harness makes the trailer brake controller a very easy installation.


Plug & play is perfect fit without too much extra wiring harness. Other vendors should take notice.


Harness made install quick. Tacoma’s trailer harness is behind the driver’s side kick panel. No tools required to pop the kick panel off just pull carefully. Trailer connection is all the way back against the firewall behind some other wires. There is a grounding screw about 6-8” in front of the harness connection on the exterior wall.


This harness was just what I needed to make the installation on the brake controller a breeze. No splicing and hoping it will work. It was definitely worth getting.

2019 Toyota Tacoma

Easy to install on my 2019 Tacoma. Definitely get the harness for plug and play.

Toyota Tacoma

Incredibly easy install in my 2021 Tacoma with towing package pre-wire. Easy in-use adjustment of braking force to accommodate a touchy set of trailer brakes. Highly recommended.

2016 Toyota Tacoma

This was a perfect fit for my 2016 Tacoma. Installed in minutes and is a must for a professional install of the Redarc brake controller. I needed this wiring harness to arrive next day so that I would be able to pickup my new trailer on schedule. I paid the extra for overnight delivery and totally came through for me. They had the item verified that it was in stock within minutes of the order and it was packaged and ready to go right on time. I received the harness before lunch the next day. This was my second order from and I'm sure it is only the beginning of many more to come.


Well made .. everything there but not used with trailer yet .. small unit offers many possibilities .. one warning, wires shorter than is preferred, make sure of wire length and connection needs before final install location decided .. length does not distract from function, just requires having options


it makes for a very tidy installation...only issue is that the correct setting is easily disturbed and results in an over application of trailer brake...may lockdown trailer wheels...but i am now accustomed to checking the setting each time i use a trailer so not a big factor ...but sure beats an awkward box hanging under the dash...


This wiring harness worked great on my 2020 Toyota Tacoma. Made the installation of my redarc tow-pro elite so easy.


Not too difficult to install. Learning process of the controller didn't take long. So much better than the previous generation of brake controllers.


This made the installation of my Redarc Tow-Pro Brake Controller a breeze!

Toyota Tacoma

Excellent! Does exactly what it should do. Looks like a factory install. Very easy to install on my 2022 Toyota Tacoma.


What a great product! Nice stealth install very clean. The controller fit nicely under the side panel where the pre wired plug was ready to go. Would very much recommend this as the only controller to use.


wiring harness clips right into factory connector just ground it and your good to go

Toyota Tacoma

Wiring harness made overall installation of REDARC Tow-Pro Liberty on my 2020 Tacoma TRD Sport a breeze. Well pleased.

Toyota Tacoma

I have this on a newer Tacoma, hook up was very easy and also the trouble shooting lights where nice on my trailer identifying a short on the brake circuit. Also easy to adjust

2019 Toyota Tacoma

This product is top notch and the price is right. Easy installation and intuitive operation. Puts the brakes on the trailer. Very happy with both the product and the process.


Made the install super easy. Well worth the extra $$$. Thanks REDARC!


Get the correct pieces for the job to help you finish in record time. Everything fit as iit should and created an enjoyable installation experience.

Toyota Tacoma

Excellent fit for the Redarc controller and direct plug in for a Tacoma.


This is an ideal solution for a smaller vehicle., it doesn’t take up any space, looks great and provides the control needed when pulling a trailer with brakes.

2021 Toyota Tacoma

Took 10 minutes to install , works great

Toyota Tundra

My '15 tundra had the factory harness right behind the tow/haul switch to the right of the steering wheel as described in the install instructions that came with the redarc harness. Just pop the whole panel off that houses all 3 buttons and you will see the harness. Plug right into that with the harness, white wire goes to a good ground (tundras have a commonly used ground behind the plastic shroud that is to the left of the parking brake.) All plug and play from there.
