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..

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



by:
Dodge Ram Pickup

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



by:
2018 Dodge Ram Pickup

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:
2021 Ram 1500

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.



by:
2019 Dodge Ram Pickup

Perfect fit for my 2019 Ram 1500 classic. Awesome plug and play harness.



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:

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:

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:
2015 Ram 1500

Already had controller,new truck,plug and play easy



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:
2016 Ram 1500

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.



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!

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:

easy install perfect fit

Perfect fit and function



by:
2020 Ram 1500 Classic

Make installation very easy



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:

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!

  • Will Redarc Tow-Pro Elite Brake Controller Fit a 2022 Ram 2500
    The Redarc Tow-Pro Elite Trailer Brake Controller # RED44FR is an excellent choice for a brake controller and it will connect directly to the OEM connector near the driver's side dash of your 2022 Ram 2500 with the Plug-and-Play Wiring Harness # 331-TPH-020 you were looking at. Attached are a few videos for you to check out.

  • Recommended Trailer Brake Controller For a 2022 Ram 2500
    I recommend the Redarc Tow-Pro Elite Brake Controller # RED44FR for your 2022 Ram 2500. This will connect with the Plug and Play Wiring Harness # 331-TPH-020 to the under dash connector. I prefer this controller over the Curt Echo # C27JR with the Adapter # C51458 and factory options as it gives you more adjustability and is easily controlled with the dash mounted control knob. While the Curt is easy to install you have to control everything from your smart phone including adjusting braking...

  • Will The Tekonsha 3020-P Brake Controller Wiring Harness Work On A 2017 Ram 1500
    The # 3024-P is the correct wire harness for your 2017 Ram 1500, the 3020-P is for select models from 1995 - 2009 so it would not work for you. The parent company for Tekonsha was recently bought out (2023) and is going through some transitional growing pains and that has caused a massive amount of their wiring harness to run out of stock so that's why you haven't been able to find it. We're still working with the new ownership to get these items back in stock but don't have a set timetable...

  • Recommended Brake Controller for a 2018 Ram 1500
    We have many brake controllers that would work great with your 2018 Ram 1500. I recommend the Tekonsha Prodigy P3 Trailer Brake Controller # 90195 and the Tekonsha Plug-In Wiring Adapter # 3024-P. This brake controller will plug directly into the factory wiring harness under the dash on your drivers side. I also love how the Redarc Tow-Pro Elite Trailer Brake Controller # RED44FR, # 331-TPH-020 installs and operates. The control module can be installed in any orientation behind the dash...

  • Wiring Adapter for 2021 Dodge Ram 1500 Classic
    The plug and play harness for your 2021 Dodge Ram 1500 Classic is item # 331-TPH-020. This harness will connect to your Redarc Liberty Brake Controller item # RED44FR and give you the port that plugs directly into your Dodge truck underneath the dash.

  • Can Tow Pro Elite Brake Controller Install in 2017 Ram 1500 and Toyota Tundra
    The Redarc Tow Pro Elite part # RED44FR is a great fit for both of the vehicles you mentioned. To install it in the 2017 Ram 1500 all you need is the # 331-TPH-020 and you'd be set. Then to install it on the 2017 Toyota Tundra you'd just need the part # RED99FR. While we don't have an install video for either truck the process is very simple and similar to the standard install that uses factory wiring.

  • Recommended Replacement for Factory Brake Controller On 2015 Ram 2500
    I have some great options to replace the factory brake controller on a 2015 Ram 2500. If you want to opt for a wired plug-in type, I recommend the Redarc Tow-Pro Liberty Brake Controller part # RED24FR as there are few others that can compare at this price. It will be mostly hidden just like the factory brake controller but outperforms it 10-1. It would also require the Redarc Plug-and-Play Wiring Harness for Tow-Pro Trailer Brake Controllers part # 331-TPH-020. Once you unplug the factory...

  • Best Trailer Brake Controller for 2019 Ram 3500
    The best trailer brake controller for your 2019 Ram 3500 is the Curt Echo Wireless Trailer Brake Controller # C51180. There a number of reasons why the Echo stands above the rest - effectiveness and ease of use. It is a proportional brake controller which responds to the deceleration of your truck for smooth braking (you will not have to push any buttons to activate your trailer's brakes), and is easily set up with an app on your smartphone. So not only are you getting outstanding trailer...

  • Parts Needed To Install Redarc Tow-Pro Elite Trailer Brake Controller On 2024 Ram 1500
    To install the Redarc Tow-Pro Elite Brake Controller # RED44FR on your 2024 Ram 1500 you only need the Plug-and-Play Wiring Harness # 331-TPH-020. This will connect to the factory trailer wiring behind your dash so you will not need to splice into any wiring.

  • Discreet Brake Controller Option For 2019 Ram 1500
    I have the perfect option for a discreet brake controller in the 2020 Ram 1500 cab. I recommend to use the Redarc Tow-Pro Elite Trailer Brake Controller part # RED44FR with the adapter plug part # 331-TPH-020 which will plug in underneath the truck's dash. The main unit of the Redarc can be mounted in a out-of-the-way location so you don't have to find a spot to install a bulky brake controller in the cab. The brake controller settings are controlled with a small knob that can installed...

  • Recommended Trailer Brake Controller For A 2022 Ram 2500
    If you're looking for a brake controller that only has a small knob visible and plug-and-play wire harness then the Redarc Tow-Pro Liberty Brake Controller # RED24FR along with part # 331-TPH-020 is going to be the best option. The small profile of the control knob will provide a clean factory look and plenty of versatility on where to install it. I have one myself in my Silverado and it's the easiest brake controller to install and use. The plug-and-play wire harness will make interfacing...

  • Recommended Brake Controller For A 2018 Ram 1500
    Factory brake controllers seem to unfortunately be very temperamental and usually quite a bit more expensive that an aftermarket brake controller so I have to recommend going with an aftermarket option. Luckily there is a brake controller port so integration of the brake controller's wiring into your 2018 Ram 1500 will be easy peasy. I recommend the Redarc Tow-Pro Liberty Brake Controller # RED24FR along with the Redarc Plug-and-Play Wiring Harness for Tow-Pro Trailer Brake Controllers...

  • 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.

  • Parts Needed To Install Redarc Tow-Pro Liberty RED24FR In 2021 Ram 1500 Big Horn
    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.

  • 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...

  • 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.

  • Does The 2019 Ram 1500 Need To be Flashed To Install a Redarc Tow Pro Liberty Brake Controller?

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

  • Troubleshooting A Service Trailer Brake System Warning Light In A 2014 Ram 1500
    If your service trailer brake system indicator light comes on then there are a few common things to check. The first being the trailer wiring if you're only experiencing this issue when connected to the trailer. This could be a a loose or corroded ground connection on the trailer or a short in the output wire for the brake assemblies. It also wouldn't hurt to check the 7-way on your Ram to ensure everything is functioning properly as well. If you're receiving this error without a trailer...

  • Recommended Brake Controller for a 2016 Ram 2500
    I would be happy to! The best option for a plug in brake controller for your 2016 Ram 2500 is going to be the Redarc Tow-Pro Liberty Brake Controller item # RED24FR. This is a proportional brake controller that activates your trailer's brakes when your Ram decelerates. The reason the Tow-Pro Liberty is the best option is because of its unique installation method where the only visible portion is the control knob that's about the size of a nickel. The main unit is hidden away inside your...

It only requires three fasteners to attach and will provide a 6,000 lb gross trailer weigh rating. In regards to a brake controller, the Redarc Tow-Pro Elite Trailer Brake Controller part # RED44FR will be our best option and it offers plug-in play installation using the Redarc Plug-and-Play Wiring Harness part # 331-TPH-020.
