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 "etrailer.com", 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..

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.



by:

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.



by:

Super Fast Delivery! Totally knowledgeable about everything I needed and answered all my questions to be sure I got just what I needed. This outfit really knows what they are doing! Highly Recommended!

Its great. There wasnt a pre-made harness for my 2005 Dodge RAM pickup, but the truck itself was pre-wired for a trailer with a connector plug under the dash. I got a universal adapter for the pre-wired truck plug and spliced it to the REDARC plug, plugged in my flatbed trailer then calibrated the brake unit and everything works perfectly. A GREAT unit!

@Robert We're glad to hear you're happy with it!


by:

When you need a quality part for your Trailer or Tow Vehicle, there is only one place to shop eTrailer. I have bought replacement lights, water heaters and several brake controllers for my Trailers and trucks. Good quality parts with excellent instructions and Technical Support.



by:

Had to hook the trailer up to the truck to test it. It wouldn’t calibrate without a trailer hooked up but seems to be working fine. I like the small size and it being mounted in the dash. Hope it continues to work well.



by:
Dodge Ram Pickup

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.



by:

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.



by:
2015 Ram 1500

Already had controller,new truck,plug and play easy



by:

Easy to install. Happy Etrailer provided video to properly install. Can't say the manufacturer instructions were all that clear, but not faulting them.



by:

Perfect fit and function



by:

The Redarc trailer brake controller bolt stripped out upon trying to tighten it. Contacted Etrailer and they said they wouldn’t warranty it and I would have to contact the manufacturer. I’ve spent so much money here and I think it’s a joke they won’t warranty something I bought from them. I guess it’s time to start buying trailer supplies elsewhere.



by:
2020 Ram 1500 Classic

Make installation very easy



by:

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.



by:

Very easy installation. Good instructions came with.



by:

WOW!!! Ordered by phone and explained that I was leaving for a vacation in 2 weeks and was assured that I would receive these parts by the end of next week. 2 days later it was in my mailbox. Couldn’t ask for better service! Thank you Gwen!



by:

Everything went together and worked per fectly



by:

Was easy to install, doesn't take up a lot of room.



by:

So far so good, easy installation. The wiring harness makes it simple.



by:

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!



by:

Great service!



by:

Looks as this installation will be a snap from the intuitive videos at etrailer! Can't wait to start the project!



by:

The controller was easy to install after I watched a video on the installation. The instructions for insalling the control did not show where the brake control plugged in. I have not tried pulling a trailer yet.



by:

The wiring harness was invaluable for making my Redarc controller installation both simple and easy.

Big J.

3/26/2022

It works as well as the day it was installed.



by:
2019 Ram 1500 Classic

Plug and play as promised. Only thing to add is that you really need to pay attention when ordering as a package because the site does not automatically add the correct harness for your truck even though you have inputted all of your vehicle info.



by:

It looks good and everything, easy install as long as you have some of an idea of what you are doing. The one thing I don’t like about it is that the part that the knob connects to feels really cheap.

  • How to Install Aftermarket Brake Controller on 2015 Ram 1500 With Factory Brake Controller
    According to my research, the factory controller will indeed need disconnecting before you install the aftermarket controller. Before disconnecting the ITBC (Ram-speak for the factory brake controller), you'll need to get the computer flashed at the dealer so that disconnecting the controller doesn't set off warning lamps/buzzers. I was told that the aftermarket controller would not work with the factory controller still installed. For your Tow Pro Elite, you'll also need the # 331-TPH-020...

  • Does 2022 Ram 1500 Need to be Programmed to Work with Redarc Tow-Pro Liberty Brake Controller
    The Redarc Tow-Pro Liberty Brake Controller # RED24FR will fit to the connector on your 2022 Ram 1500 by using the Wiring Adapter # 331-TPH-020. As long as you aren't replacing an OEM controller you'll be able to just plug this into your truck and be good to go without getting anything programmed or flashed by a dealer! Attached is an installation video of this kit on a 2016 Ram truck for you to check out.

  • Parts Needed to Install Redarc Tow Pro Elite on 2019 Ram 1500

  • Redarc Trailer Brake Controller For a 2021 Ram 1500
    Yes the Redarc Tow-Pro Liberty Brake Controller # RED24FR and the Redarc Plug-and-Play Wiring Harness # 331-TPH-020 are the correct parts for your 2021 Ram 1500. You should not need any other parts for this to operate unless fuses were left out from the factory. Be aware that the connection point for the wiring harness is behind the center of the dashboard near where the factory harness will install. To test this brake controller you will need a trailer to connect to, otherwise you...

  • Parts Needed to Install Redarc Tow-Pro Elite Trailer Brake Controller on 2019 Ram Classic
    To install the Redarc # RED44FR Tow-Pro Elite on your 2019 Ram 1500 Classic, the only other thing you'll need is the wiring harness, which is part # 331-TPH-020. The harness will plug into the factory tow package connector that's located under the dash above where the driver's right knee would be, as shown beginning at the 1:45 mark in the linked installation video. I've also linked to a video showing how the Tow-Pro Elite works. The Tow-Pro Elite does include a universal mounting bezel...

    To install the Redarc Tow-Pro Liberty # RED24FR in your 2021 Ram 1500 Big Horn you will need the Plug-in Adapter # 331-TPH-020. The # 331-TPH-020 will plug in to the factory trailer brake controller port underneath the dash of your truck and then into the Liberty # RED24FR. This will be the only wiring connection you will need to make. I included videos of the products mentioned for you to take a look at.

  • Is There a Way to Tell if the Redarc Tow-Pro Liberty is Hooked Up Correctly without a Trailer
    While there is not a way to test the "full" scope of working properly, you can definitely ensure that it is receiving the proper power and starting the calibration process. A trailer does need to be connected in order for the LEDs to be on when using the Redarc Tow-Pro Liberty Brake Controller # RED24FR. If you press the manual override without a trailer connected, the led light should flash blue, but go out again, which means the controller does have power. Even without a trailer connected...

  • Will The Redarc Tow-Pro Elite Brake Controller Fit a 2022 Ram 2500 Without Factory Brake Controller?
    Yes, the Redarc Tow-Pro Elite Brake Controller # RED44FR will connect to your 2022 Ram 2500 using the Plug-and-Play Wiring Harness # 331-TPH-020. The connector is found on all the Ram 2500 trucks regardless if it came with a factory controller. Not having a factory controller will make the installation easier as it does not require having the factory ECU flashed to remove the controller.

  • OEM vs. Aftermarket Brake Controller for 2018 Ram 1500 Tradesman
    I doubt you'd be able to increase the asking price of your 2018 Ram Tradesman if you installed the OEM brake controller but I would think that it could only help in selling process to be able to say that option is on the truck. The truck market is pretty crazy though so I doubt you'd have any trouble selling the truck either way and will probably be able to ask a premium price. If you wanted the best function and safety though you really can't beat aftermarket brake controllers like the...

  • Does The 2019 Ram 1500 Need To be Flashed To Install a Redarc Tow Pro Liberty Brake Controller?
    You will not need to have the computer on your 2019 Ram 1500 flashed when you install the Redarc Tow-Pro Liberty Brake Controller # RED24FR with the Redarc Plug-and-Play Wiring Harness # 331-TPH-020. The factory computer only needs to be flashed if you are adding or removing a Ram integrated brake controller on your truck.

  • Brake Controller Recommendation for 2024 Ram 2500
    For your 2024 Ram 2500 I highly recommend the option from Redarc, and you'll also need the wiring adapter: - Redarc Tow-Pro Elite Trailer Brake Controller # RED44FR - Redarc Plug-and-Play Wiring Harness # 331-TPH-020 I really like the Tow-Pro Elite because of its control knob which keeps a cumbersome unit out of your cab, and because it gives you more control over your trailer braking power than any other brake controller. The control knob of the Tow-Pro Elite can be installed anywhere...

  • What Brake Controller Do You Recommend For My 2022 Ram 1500 Classic
    We can get you setup with a brake controller for your 2022 Ram 1500 Classic. The nice thing is once you have the brake controller setup you will be ready to go since your Ram 1500 already has 4-way and 7-way connectors installed. My brake controller recommendation will consist of the following: Redarc Tow-Pro Elite Trailer Brake Controller - 1 to 3 Axles - Proportional, part # RED44FR and Redarc Plug-and-Play Wiring Harness for Tow-Pro Trailer Brake Controllers, part # 331-TPH-020.

  • Where Does Redarc Tow Pro Brake Controller Install on 2022 Ram 1500
    On your 2022 Ram 1500 the brake controller install harness you are looking for is under the dash, to the right of the of the steering column taped to another harness. The install harness part # 331-TPH-020 is correct for your truck to install the Redarc Tow Pro Elite # RED44FR. You can pretty easily hide the brain/module of this controller under your dash like you are wanting to do as well.

  • EOH Trailer Brakes Do Not Activate With Time-Delay Controller When Brakes Applied in 2019 Ram 3500
    That's a good question, and the reason your electric over hydraulic brakes are not activating is because the time-delayed brake controller is not compatible with electric over hydraulic brakes, so what you'll need to do is get a brake controller that is compatible. For that I strongly recommend the Redarc Tow-Pro Elite Trailer Brake Controller # RED44FR, and since you have the factory 7-way you will only need the Redarc Plug-and-Play Wiring Harness for Tow-Pro Trailer Brake Controllers...

  • Location of Brake Controller Plug on 2019 Ram 3500
    The brake controller port for your 2019 Ram 3500 is a bit of an odd location relative to where the port is on other trucks; the port is underneath the control knobs like in the accompanying photo. You will be able to find the plug behind that panel, which has clips you can remove. Doing this will allow you to plug in the Redarc Plug-and-Play Wiring Harness for Tow-Pro Trailer Brake Controllers # 331-TPH-020 so you can use the Redarc Tow-Pro Elite Trailer Brake Controller # RED44FR.
