This breaking system is very good, it’s been a year now without any problems.

About a year ago I called etrailer looking for a brake controller for a Lexus LX600. They couldn’t be more helpful. Of all the local places I called, nobody had a clue and couldn’t help me. Then it hit
Me. I recalled my last experience with these guys and they saved me and walked me through the installation. You can’t find that kind of service anywhere these days.



by:

This fit the lower dash panel on my 2105 Highlander. The blank was a pain in the butt to get at from the back side to push out, so I made certain the controller was properly installed on it before pushing it in. Worked out well.

I am very careful with anything for my Taco. I had to install a brake controller to tow a double axle trailer with electric brakes. The Redarc Elite was not only easy to install it exceeded my expectations in its operation. Above all the control switch for it looks as good as a factory install. Nice job.

Have never dealt with a company more on top their game…excellent customer service and follow-through. Personalized, friendly, coordinated ordering. Even provide direct line contact to the CSR that assisted with my order in case there are issues or need to contact for additional equipment.
Excellent how-to videos at every turn!
By far the best experience ever with on-line retail. Josh was 10+

Perfect fit in our 2020 Toyota 4Runner. Saved me from drilling out an exiting switch blank, so if I were ever to remove the controller to sell the truck it could easily be returned to stock.

Oddly, the trim bezel that comes with the TowPro Elite to go behind the control knob won't fit properly, as the knob can't be depressed when it's in place. No matter, as it's not needed anyway and looks fine without it.

Still pleased with how this switch fits and integrates into our 4Runners instrument panel. I wasnt certain that using the far left side blank would prove convenient rather than the partially hidden one to the right of the steering column thats closer to hand, but it has proven to be a good, readily accessible place for the control knob. Also loving the RedArc TP Elite controller. Strongly recommend it. Note that while the application list shows 2009-2012 4Runner for this mounting panel, it fits perfectly in our 2020, and should therefore fit MY2010-2022 models, since they use the same switches and blanks.

I am so pleased with etrailer's products. I have ordered from them before and received the perfect part to my vehicle. This time I ordered a Plug and Play Tow-Pro Trailer Brake Controller with a Control Knob mounting plate that fits perfectly with my install. Very professional. The parts came in as was promised. Very happy with the service and the products! Thank you ETrailer!

Looks nice, but did not fit my 2005 Tacoma. It was not listed to fit, I just took a gamble. I just modified my existing blank knock out.

Hey J, I reached out to Redarc and the panel is reversible as needed. If you pop off the button panel by pressing on the two clips to release the switch insert it can be turned 180 degrees to the correct orientation. Then it can be pushed back into place again.



by:

Just as easy as can be. Test run was successful on my new TA trailer.

Haven't installed it yet, but looking at the etrailer installation video, it should be an easy install. Great help from Andrew in customer service to make sure I ordered what I needed

Mounting panel insert for Redarc Tow Pro Elite brake controller installation

This insert is for a 2020 Toyota Tacoma and is pre drilled for the Redarc Tow Pro control knob. Just snap it in place where the blank insert was located, eliminating the need to drill holes in the original insert panel. Makes the job neater, quicker and professional looking. See accompanying photo.
I am very happy with all the products I have received from eTrailer



by:



I wanted to follow up and thank
you for your help! I was able to install the Redarc brake controller with no problem! Thanks for your assistance and recommendations.

One note...There are not a lot of late model Land Cruisers on the road. Toyota only sells about 3-4,000 a year so finding videos and guides for installation is a bit of a challenge. I found some FAQ's on etrailer.com but the information seemed inaccurate or at least not very helpful.

I know the LC comes with a two package and is prewired but it takes some doing to locate it. I remember directions and I found some install help on another site and that helped.

In any event, I appreciate your help. I have attached a photo of the installed Redarc!



by:

The Redarc Pro Liberty Brake Controller came with both types of mounting panels. So I have two extras of each type. Wish the description of the Brake Controller told us that. Both mounting panels work great and are an exact fit for my 2021 Tacoma.



by:

This mounting panel for my RedArc controller worked great on my 2022 Tacoma OR . I did have to trim a bit of plastic to make it fit . No big deal .

Very happy mounting panel. Looks factory equipment in my 2019 4Runner. Or at least it will when I white out the letters like another reviewer did.

Shortly after I wrote this review I used liquid white out to fill in the letters. Looks like it came from the factory.

Received package okay and installed it in a couple of hours into 2021 4RUNNER. You can almost get away with not removing any panels as I reached up and replaced plug no problem but I did remove panel by the mat to place the main unit. I also ordered the knock out and used the spot by the inverter and not lower left as some videos showed. Lights up and will test when trailer arrives. Cheers



by:

This part fit my 2022 4 Runner just fine but I didn't realize that the Brake Controller kit came with one already so I didn't end up needing it.



by:

So far everything is working fine wirering and red ark braking system easy DIY video installation from etrailer looking forward to next season.

etrailer.com is the best online retailer I have dealt with. They have the best products. And when you order from them, they keep you informed each step of the way - from receiving your order, to packaging, to shipping, to delivery. Awesome company. Highly recommended.

  • Recommended Brake Controller and Wiring Harness for a 2025 Toyota Tacoma
    There is a wiring kit for a brake controller Preston but it's not going to be a plug and play one. The 2025 Toyota Tacoma does not have a plug in brake controller port. Toyota stopped putting them in after the 2023 model. For your Tacoma, I recommend the Redarc Tow-Pro Liberty Brake Controller w/ Universal Wiring Harness item # RED52VR. This is a proportional brake controller that activates your trailer's brakes when your Tacoma decelerates. The reason the Tow-Pro Liberty is the best...

    Yes, the Tekonsha OEM Replacement Vehicle Wiring Harness item # 22119 will fit your 2019 Toyota Highlander. This will provide you with a 7-Way connector and a Tekonsha brake controller adapter. This wiring harness is custom fit and plugs directly into a port in the cargo area of your Highlander. The only wiring you will have to do is for the brake controller adapter. I have linked an installation video below. For a compatible brake controller, I recommend the Redarc Tow-Pro Liberty...

    Hi Mark; you can add a 7-way using the Tekonsha OEM Replacement Vehicle Wiring Harness # 22117 if you want or you can use the # ETBC7. The Tekonsha is a full replacement, including the 4-way. The # ETBC7 will save you some money since it doesn't have extra parts you don't need. The Redarc Tow-Pro Liberty Brake Controller # RED24FR and Mounting Panel # 331-TPSI-002 are also correct. However, the wiring harness will depend on the 7-way you add. If you decide to use the Tekonsha then you...

    Hey Nancy, thanks for the information.

    Hey Zach, to convert the 4-way of your 2017 Toyota Highlander to a 7-way and install a brake controller requires the adapter part # ETBC7. This comes with everything needed to make the conversion as well as wire in a brake controller. If your current 4-way is trashed you could cut it off and cut off the ETBC7 4-way and hardwire the wires to each other.

    You are already on the correct track. In order to install a 7-way on your 2011 Toyota Rav4 you have to have a 4-way installed first. Since you already have a 4-way you can use the Universal Installation Kit for Trailer Brake Controller # ETBC7 to adapt your 4-way into a 7-way. You would still want to run the second power wire to the battery. The wire for the 4-way is only 10-amp while the 7-way wire is 40-amp and they are serving different purposes.

  • Difference Between Prodigy P2 and Redarc Tow Pro Liberty Brake Controller 2011 Toyota Sequoia
    The braking is going to be about the exact same between the Prodigy P2 part # 90885 and the Redarc Tow Pro Liberty part # RED52VR. The main difference will be that the Redarc only puts a small know on your dash and the P2 is a traditional brake controller that is much bigger. To install either controller you'd need the install harness part # 3040-P. For how much cleaner of an install the Redarc provides that would be the route I would go with. For tow mirrors the K-Source set part # KS81300...

  • Correct Redarc Mounting Panel For 2021 Toyota Tacoma TRD Offroad

The main difference between the # 331-TPSI-002 and # 331-TPSI-007 is the different vehicle years they fit. Both of these parts will fit a Tacoma but the # 331-TPSI-007 fits a 2005-2011 Tacoma while the # 331-TPSI-002 fits a 2015 to Current Tacoma. This will go on the center console switch like in the picture below.

Sometimes it isn't seated all the way and that can cause problems. Based on the overall behavior you described...
