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

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:
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:
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:

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:
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:

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:

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!

by:

Very easy installation. Good instructions came with.



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:

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!

  • 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.

  • 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...

  • 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...

  • 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.

  • 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...

The control knob of the Tow-Pro Elite can be installed anywhere...

The harness plugs into the connector located above where the driver's right knee would be, as shown at the 1:18 minute mark in the linked video.

  • 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...

  • 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...

    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...

    An aftermarket brake controller can absolutely be added to your 2018 Ram 2500 Diesel Truck. I've attached an article to assist with this. My recommendation is to use the wiring harness # 3024-P which is a custom fit and then use the Prodigy P3 # 90195 which is our best selling controller due to all the features. I've attached a video to assist. We also have a newer controller that is much more of a factory look that is very popular and fits in your dash instead of attaching to it....

    Yes, you can absolutely install an aftermarket brake controller like the Tekonsha Prodigy P3 Trailer Brake Controller part # 90195 on your 2019 Ram 1500. There won't be any dealer programming required either. For this, you will also need the Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers part # 3024-P which makes for a plug and play install. That said, the Tekonsha Prodigy P3 is no longer the top dog when it comes to aftermarket brake controllers. I instead recommend...

  • 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...

  • 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...

  • Replacing the Factory Brake Controller on a 2017 Ram 3500
    Yes, you can replace your 2017 Ram 3500's factory brake controller with the Redarc Tow-Pro Elite item # RED44FR. You will also want the Redarc Plug-and-Play Wiring Harness item # 331-TPH-020. This will allow you to plug directly into your trucks brake controller port and avoid having to cut or splice wires. An aftermarket brake controller will not function properly unless you have the dealer remove the factory integrated brake controller (ITBC) from the computer.

This is a proportional brake controller that automatically adjusts the trailer's braking based on the deceleration of your vehicle.

    From what you've described, the Hydrastar Electric Over Hydraulic Actuator for Disc Brakes - 1,600 psi # HBA16 is exactly what you need for a replacement Hydrastar actuator. The Adapter Module # HBA-CAM shouldn't be needed for the OEM controller in your Ram truck, and unless you're experiencing issues with the brake controller right now, you don't really have a reason to replace it. If you end up wanting/needing to replace your OEM controller then I recommend picking up the Redarc Tow-Pro...
