Custom Wiring Harness for Redarc Tow-Pro Liberty Installation on 2025 Toyota 4Runner

Question:

Hi. I found the Redarc Liberty brake controller on your site but I see a lot of different options for it. I'm looking for one that will plug into the tow port on my 2025 4Runner with the tow package. Which is the right part?

Hi Kim; sorry for the trouble, I know it can be difficult to sort through all of the listings for the Redarc Tow-Pro Liberty on our site. Since you have the factory tow package on your 2025 4Runner the # RED82CR is what you need. This comes with the brake controller and the custom wiring harness that will plug right into your tow port for a simple installation.

I went ahead and added an installation video below for your reference.

Hey Kim, how did things go with the Redarc Tow-Pro Liberty and the custom harness on your 4Runner? Did the plug-in connection to the tow port work as smoothly as expected? Your update could make it easier for the next person with the same setup.
