Speaker 1: Today we're taking a look at the Redarc plug and play wiring harness for the tow pro trailer brake controllers. This wiring adapter eases the installation of your Redarc tow pro classic or tow pro elite electric brake controller. The custom connector end plugs into the port beneath your vehicle's dash so this is a vehicle specific wiring harness. And then the other end plugs into the tow pro electric brake controller. Now if you're using this on the tow pro elite, it plugs directly in there. If you're using this on the tow pro classic, some wire splicing is required.I also want to point out that it has a protective mesh that goes over the wires.
It keeps the wires bundled together and protected. That's going to do it for today's look at the Redarc plug and play wiring harness for the tow pro trailer brake controllers.
Could very well be the easiest brake system to install.Functions superbly and most of all not intrusive like the old style brake controllers.If you are thinking about purchasing one watch the install videos on etrailer, they have a few for different models of vehicles. Make sure to get the adapter cord that fits your car or truck, makes installation a breeze. Highly recommend!
Well built cable. How ever this cable will not fit a 2025 1500. The connection to the truck harness needs to be a female end. This cable has a male end. After looking for a different cable with no luck, I just cut the connector off and spliced into the trucks trailer brake harness with no issues.
This is the best brake controller I have owned. So easy to install especially if you by the harness for your year vehicle looks great to no ugly controller taking up room

Woohoo! Glad this one is topping the charts! And just out of curiosity, what are some of the other brands you've tried?
Performed as expected. No difficulty with installation.
I installed this on my 2021 RAM 1500. If your truck has a "towing package" but no factory brake controller, this is what you need to hook up your Redarc brake controller. Watch the videos, it's not a simple job but most people can handle it.
Very easy install plug and play great p roduct!
Saw a YouTube video from etrailer installing on a 2020 ram 1500, very instructional to the point, detailed, I got it done in about an hour. Took my camper for a test drive just like the video said it was blinking blue and green eventually turned blue after it calibrated. Found a setting that worked for me after that, thank you! Sleek design compared to the bulky old systems
Harness does exactly what it is supposed to do, connection from Redarc TowPro Elite controller into 2021 Ram Rebel factory harness. Tested all wires on bench prior to installation and everything checked out, and no loose terminal ends in cheap connector here at all.

A year later towing with our 21 Ram Rebel 1500 and everything is Still spot on. Redarc TowPro Elite controller with harness from etrailer is the best self-calibrating unit I have ever used.
I already used this product once on my Jeep gladiator so I expected it to work just like I have on my ram pick up truck
Easy to install. Happy Etrailer provided video to properly install. Can't say the manufacturer instructions were all that clear, but not faulting them.
Etrailer's web site determined which wiring harness I needed based on my vehicle. It fit perfectly and was delivered along with the controller in just a few days. I don't know what else you could ask for.
This harness worked well for hooking up my Redarc brake controller to my 2020 Gladiator. Two wires need to be reversed. There is a youtube video on how to do that. It's very easy.

Worked great for 18 months and then I sold the trailer. Still 5 star!
Trailer brake install video specific for my Ram 1500 truck was very helpful. Ram connection cable was perfect fit.
The tow mirrors will work fir now until I decide on vehicle tow mirror replacement
Works as advertised. Excellent video on how to install made it easy to follow along. Pretty much plug and play. Easy to adjust and easy to use and get to. Had an Echo controller before and was ok in a pinch but was erratic plus fumbling around with cell phone is not the easiest and safest. Installed on 2018 Ram 1500.
The wiring harness was invaluable for making my Redarc controller installation both simple and easy.

It works as well as the day it was installed.
Easy install and looks great. No controller hanging under the dash.
Quick shipping. Pleasure to do business with etrailer.
Great selection. Easy to find the specific part I needed (brake controller adapter harness). Great price, extremely fast shipping (within hours), excellent communication (email). Very satisfied customer.
Trailer brake controller works perfectly. Good control of trailer braking with a dial of the knob.
Installation of electrical was easy with plug and play harness, however the mechanical installation took some time.
Very satisfied with the product.
It's plug and play but the installation of the knob was difficult cause the manual override wouldn't work and took some work to get it in but still haven't got it right but it works.
Fit 2020ram 1500 works great so far
Perfect fit for my 2019 Ram 1500 classic. Awesome plug and play harness.
This unit connected easily to the truck's quick connector for trailer brakes. Couldn't be happier with the Plug and Play Harness and with the Redarc controller.
As always, it’s just what I needed Thanks to the phone helper who figured what was best.
This wiring hooked up to the factory harness on my 2022 Ram 2500 without any problems. Have not tried the entire braking system out yet but it seems to be working without a trailer.
Shipping was fast but controller came without the knob. Chatted with etrailer and knob was ordered (I hope). Install was clean and fast following the video on the site. Havnt pulled the trailer yet. Overall so far so good.

Sounds like Redarc is really a show "stopper"! I'm happy to hear the install was a breeze!
