Redarc Tow Pro Liberty Brake Controller Installation for a 2026 Honda Ridgeline  

I have installed the RedArc controller on two Ridgelines, a 2019 and 2026. With the adapter cable there is no wiring to do. It all just plus in. That being said, it does take some awkward bending and reaching to make connections. On the 2026 I had to remove the left lower dashboard panels to gain access to the plug to make the connection. There is a video that shows you how to do this and you only need a plastic pry bar to get them off. You also need to find a place to mount the braking level knob. It is either drilling a hole through the dash or using the custom switch cover from trailer. I have done both I would say if you are not handy this could be intimidating, but doable. You could have it installed or buy one that does not require so much hands on.

I installed a Redarc Towpro Liberty in my 2022 Ridgeline. It didn't require any wiring with the proper wiring harness, just plugging it in and zip-tying the controller under the dash. The hardest part was mounting the control knob. I had a blank switch position, so I modified the blanking plate for mounting the knob, which required both drilling a hole in the plate and snipping out some of the reinforcing plastic in the plate.

I installed one on my 2025 Ridgeline. There is a wire with a connector under the dash above the emergency brake pedal. Just plug into that, and it’s connected. I anchored the unit using Velcro tape and attached it under the dash lip behind the steering wheel housing. It involves a little twisting and contorting yourself to get the right angle. I used the switch blank near the parking alert and lane departure control switches and fastened the control knob with a universal plate cover. It works great and operates seamlessly when towing. Haven’t had to use the manual override in real life, just to test the system and it works well.

Installed a few months ago in my 2024 Ridgeline RTL. I had a blank cover that I removed to accommodate the switch assembly but instead of using a plastic pry tool (and possibly breaking something), I used either my index finger or thumb to depress and push the top or bottom clip in back. Once one of the two clips is released, the blank cover will easily come out. My truck did have the wiring harness above the parking brake; however, connecting it is challenging because you must lie on your back using a headlamp and there is only room for one adult hand up there (I did not want to remove the panel). Same with securing the Liberty to a metal bracket which I did with two zip ties, also one-handed! I bought some Extreme Velcro strips which I keep in the truck in case a tie breaks. Once the switch assembly is installed, it looks factory installed. Employed the controller on six fly fishing trips this summer and it worked great. Probably helped me avoid colliding with some ungulates.

I installed the Redarc in my 2025 Ridgeline. It truly is plug and play. I am not really a handy person and I was really nervous about the install. I can honestly say it went extremely well! The directions and YouTube made it super easy. Good Luck, you can do it!
