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..

Install your Redarc Tow-Pro electronic brake controller (sold separately) quickly and easily with this custom wiring adapter. Plug one end of the adapter into your Tow-Pro brake controller and plug the other end in beneath your vehicle's dash.

by:

VERY happy with the ease of installation. I had an insert made on a 3D printer to mount the control where the factory brake would have mounted.



by:
2015 Toyota 4Runner

The name says it all, it truly was a plug and play experience installing the wiring harness. I realized after the harness arrived that my 4Runner came with a cable with one end ready to plug in and the other end ready for a connector. Although I could have saved a little money terminating it myself, I went with the premade Redarc harness and was done in minutes. I have no regrets, it was money well spent and I was on the road in no time. Highly recommended.



by:

This is my 3rd redarc. It’s a great product compared to a conventional brake controller hanging under the dash. The main downside to the redarc is the control knob. You can’t see the numbers very well to adjust it while driving, as they are not well lit. Otherwise, it works as expected



by:
Ford Edge

After a year of owning and pulling a camper it has been flawless. Easy install. I will say do your research on the best way to set it up for your vehicle. I drove on dirt roads around 5mph and adjusted it until I was right on the edge of skidding the trailer by pressing on the controller.



by:

Not safe to use, very poor quality product. May cause and accident due to not working properly with a brake controller. Do not buy it! It is not compatible with anything.



by:

It wasn't plug and play with the factory setup. Had to cut the harness and install my own wires and breakers.



by:

What can you say, "Plug-and-play" worked as it should.

Still love it.



by:
Toyota 4Runner

Love that it is mostly plug and play. 4Runner is already wired for a brake controller and the cable I ordered made it simple to just plug it in. I didn’t get the custom switch blank for the 4 runner so I had to modify the existing one and that was a lot of work. Would order blank if doing again. Install was pretty easy. Haven’t towed a trailer yet so not sure how well it works. Looks like factory item after installed.



by:

Perfect match to the vehicle making controller wiring a simple process.



by:
2022 Toyota 4Runner

Watched the video that demonstrated how to install the Redarc brake controller in my 4Runner. SIMPLE with the plug and play harness I ordered through you folks. In spite of it being shipped from the states to Canada, it got here in a very acceptable time frame. I believe I'll do the install tomorrow. Thanks ... BRW

2019 Toyota 4Runner

Made the brake control install very sim ple.

Still working like a factory option. Highly recommend for an easy brake controller installation,



by:

Works awesome. I purchased a separate knob panel insert which made the entire installation plug and play. Would buy again.



by:
2008 Toyota Tundra

I watched the stock video for installation on a Tundra, and it was perfect.



by:

Trailer brake easy to install....works great and accessory switch fits perfect...



by:

Very helpful and patient with my question. 1 year out and I’m very happy with my purchase!



by:

This part fits my 2018 Lexus GX460. Install was simple.



by:

made install fast and easy hence the Plug and Play



by:

I called them and needed this part overnight and they made it happen, great company to deal with and appreciate all of the help!



by:

Toyota apparently thinks if you really want a brake controller in a 4Runner, you are going to have to work for it. The wiring harness was perfect once I found the Toyota connector plug.



by:

This thing works so good. I actually went and bought a second one for the motorhome and replaced. It was one of these. This is the only one I’m buying from now on.



by:

Worked flawlessly. Everything was plug and play, had the kit installed in less than an hour. I would highly recommend etrailer to those looking for towing/trailer accessories.



by:

Just what I needed.



by:

Arrived early and looks to be the ticke t.



by:
2023 Toyota 4Runner

Nice to see companies that think of the customer, keep it simple, do the wire harness and it installs so quick and easy!



by:
Toyota 4Runner

The trailer brake controller works well and integrates well into our 4Runner.

  • Recommended Brake Controller For A 2013 Toyota Tacoma With Factory Tow Package
    Hey Jeanie, The reviews aren't false, the app that allows you to adjust your brake settings on the Curt Echo # C51180 has been having a lot of issues pairing to the phone. With you having the tow package you really should just get a dash mounted brake controller like the Redarc Tow-Pro Liberty Brake Controller # RED24FR. This brake controller has a tiny little control knob to mount to the dash so that you won't have a bulky box to hit you knee on. with the Plug-and-Play Wiring Harness...

  • Recommended Trailer Brake Controller For a 2024 Toyota Tundra SR With Factory Tow Package
    I recommend going with the Redarc Tow-Pro Liberty Brake Controller # RED24FR for your 2024 Toyota Tundra. This will plug and play into your factory harness with the Adapter # RED49FR providing a clean and easy installation. I prefer the Redarc as it allows you to only have a small dash mounted control knob rather than the large box controller mounted near your legs.

  • Brake Controller Recommendation for 2005 Toyota Tundra SR5
    Hey Deanna, the brake controller I recommend for your 2005 Toyota Tundra is the Redarc Tow Pro Liberty part # RED24FR as it only puts a small knob on the dash of your truck and uses an inertia sensor to determine how hard you are hitting the brakes for applying the trailer brakes. To wire it to your truck all you need is the correct install harness which is part # RED49FR.

  • Troubleshooting Tow-Pro Liberty Recalibrating After Trailer Disconnect
    I reached out to Redarc and it sounds like you need an extra ground wire for your Redarc Tow-Pro Liberty Brake Controller # RED24FR. There is no Redarc wiring harness available for your vehicle, but if you look at one like the # RED49FR it has an additional ground wire. This is what allows the controller to retain power when the trailer is disconnected. If you hard wired your brake controller using the Toyota provided pigtail you will need to splice an extra ground wire in with the Toyota...

If you're looking for a brake controller, the only option is to use either the Redarc Tow-Pro Elite Brake Controller # RED44FR or the Redarc Tow-Pro Liberty Brake Controller # RED24FR with the Plug-and-Play Wiring Harness # RED49FR.

  • Comparing Redarc Liberty and Elite Brake Controllers For a 2014 Toyota Tacoma TRD
    The main difference between the Redarc Liberty # RED24FR and Elite # RED44FR is the Elite allows you to switch from proportional braking to a user controlled mode which is more like a timed brake controller. The Elite also allows you to control up to 3 braking axles while the Liberty is proportional only and is able to control up to 2 braking axles. Personally I feel the Liberty is going to be the best option unless you plan on overlanding with a trailer behind your Tacoma. The Mounting...

  • Troubleshooting Difficulty Calibrating The Redarc Tow-Pro Liberty
    We have never encountered a case of a 4Runner needing a diode in order to use the Redarc Tow-Pro Liberty # RED24FR.

The Redarc Encapsulated Power Diode # RED34FR is generally only needed on vehicles with certain advanced safety systems like the Adaptive Cruise Control, Assisted Emergency Braking and Autonomous Emergency Braking. Since you are using the plug-and-play pigtail # RED49FR you should not need any...

  • Can The 2022 Toyota 4Runner Factory Pigtail Be Used When Installing A Redarc Controller?
    The only differences between the factory pigtail and the Redarc Pigtail # RED49FR (Redarc part number TPH-021) will indeed be the external ground and a diode pre-installed on the red wire. There were a few issues with brake controller wiring in the past and this was the quick and easy fix for the issue. As there is a diode included in the pigtail, you will need to add one to get the Redarc Tow-Pro Elite Trailer Brake Controller # RED44FR working properly. And just as a side note, I really...
