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..

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.


Comments
Worked great for 18 months and then I sold the trailer. Still 5 star!

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


Comments
It works as well as the day it was installed.
Big J - 03/26/2022


by:

Installation was as easy as could be expected working under a dash. Not as flexible as I once was. Wiring harness DEFINITELY worth the money. Took about an hour and a few zip ties. Much better than $xxx/hr to have it installed.




by:

Got a plug and play trailer brake adapter, and it works great. Perfect fit. It also shipped quickly and arrived soon than anticipated. The communication from this seller is fantastic from start to finish. I will certainly buy from them again.




by:

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.




by:

Had to order via phone for my tax free status. Service was great. Shipping was fast. Price was great. Product was quality and install was easy. I’ll continue to shop at etrailer. Cheers.

  • 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...

  • 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.

  • 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...

    To install an aftermarket brake controller Like the Redarc Tow Pro part # RED44FR on a 2015 Dodge Ram that has the factory integrated controller you will have to disconnect the ITBM (Integrated Trailer Brake Module). Doing so will turn on a warning lamp on the instrument cluster.

Once the TIPM has been reconfigured, and...

You should not need any other parts for this to operate unless fuses were left out from the factory.

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.

  • Recommended Trailer Brake Controller For a 2019 Ram 1500 Bighorn
    I recommend the Redarc Tow-Pro Liberty Brake Controller # RED24FR for your new body style 2019 Ram 1500 Big Horn. This proportional controller is very user friendly and has a small control knob that you can mount to your dash where it is most convenient for you. I recommend just above the CD/DVD slot where the factory brake controller would mount. You will need the Redarc Plug-and-Play Wiring Harness # 331-TPH-020 to connect to the factory connector on your Ram.

The factory computer only needs to be flashed if you are adding or removing a Ram integrated brake controller on your truck.

This will be located up under your driver's side dash to the right of the steering column. Sometimes these connectors can be hidden really well and I've seen people pull down that fascia piece below their steering wheel to make locating it easier. Once you can find that connector though the rest is just plug and play...

  • Troubleshooting Short Code with Redarc Liberty Manual Override on 2022 Ram 1500
    Yes, the Redarc Tow-Pro Liberty # RED24FR is compatible with your 2022 Ram 1500 and should plug right in using the Adapter # 331-TPH-020. It sounds like you may have a bad wiring connection or short somewhere on your brake controller circuit. It's a little unusual since you have a brand new truck so I would start with your trailer wiring and 7-Way connector. What I can see happening is the higher amperage of the manual override pushing that bad connection/short over the edge which is why...

  • 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.

  • Brake Controller Recommendation for a 2019 Ram 1500
    I recommend going with the Redarc Tow-Pro Liberty Brake Controller # RED24FR which connects to the OEM plug on your 2019 Ram 1500 by using the Wiring Adapter # 331-TPH-020. I like the Liberty because it gives you the proportional braking action that is great for highway use but it can be installed virtually anywhere inside the cab of your truck. All that's visible is the small control knob so you aren't taking up leg space in your cab either. Attached is a review video for you to check out.
