Recommended Brake Controller and Custom Fit Harness for a 2021 Toyota 4Runner w/ the Tow Package

Question

Question:

I have a 2021 Toyota 4Runner Nightshade and am looking at the Redarc tow pro liberty brake controller w/harness. I want to plug it in via an existing electrical adaptor in the 4Runner. Someone told me I need a Curt 51362 adaptor in order to make it work right out of the box. Please advise. Thank you

Hey Michael, thanks for the information! The Redarc Tow-Pro Liberty Brake Controller w/ Custom Harness item # RED98CR comes with everything you'll need for your 2021 Toyota 4Runner. You will not need a Curt adapter.

The Redarc item # RED98CR includes the brake controller and a custom fit wiring harness. The harness is designed to plug directly into the factory adaptor to the left of the emergency brake pedal. I attached a picture below of where it's located so you can verify this is the same one you're referring to.

What kind of trailer are you towing?

You can add this information, along with any other questions you have, where it says Add Comment.

@MichaelB You're welcome and thank you so much! I am always happy to help! One additional thing I wanted to add. I checked with Redarc and there are no custom fit control knob brackets for the 2021 4Runner. They stopped fitting after the 2019 model year. If you have any additional questions, don't hesitate to reach out.

Hi Dan; this is a pretty easy choice, I would definitely pick the P3 over the Curt TriFlex #C43GV. The P3 wins for reliability alone, and it has more features. The only real advantage with the TriFlex is the lower cost. However, right now the P3…
