Most brake controllers stick out and take up knee room, but this one tucks the main unit out of sight. All you see is a sleek knob on the dash that’s just 1-7/8" long and 9/16" wide. It looks like it came built into the console. That single knob handles everything—adjusting brake power, pressing manual override, and showing color-coded alerts from blue to red as braking intensity increases.
No more tugging or jerking when you brake. The internal 3-axis accelerometer senses how hard you’re stopping and matches your trailer brakes in real time. It works with electric or electric-over-hydraulic setups on trailers with up to 2 axles (4 brake assemblies). The result is steady, even braking that keeps both tow vehicle and trailer moving together.
Wiring a controller doesn’t have to be a project. This setup includes a custom plug-in harness that connects directly for a clean, plug-and-play install. The main box mounts securely behind trim using screws, tape, or zip ties within the 3' cable reach. Calibration happens automatically after about twenty brake applications—no special tools, no guesswork.
Safety standards matter when adding electronics inside the cabin. The Redarc Tow-Pro Liberty meets or exceeds UNECE R21 and FMVSS 201 regulations for interior impact safety. That means it’s designed to blend in without compromising airbag zones or occupant protection while giving you full braking control right at your fingertips.
Once installed, the small control knob looks like it belongs there—no bulky box under the dash or wires hanging down. You can mount it in an open switch panel or console spot for a tidy, OEM-style appearance that keeps your cab uncluttered while still putting all brake control functions within easy reach.

The Redarc looks great in your Jeep, Kent! What kind of trailer are you towing?

It has now been a year since I installed the brake control. I’m not a daily user, however every time I pull the trailer the controller works flawlessly and it’s convenient.

My Redarc Tow Pro Trailer Brake Controller seems to switch on and off a lot. It always recalibrates and comes up working, but the frequency of the on and off again factor concerns me. Thanks for the inquiry!

Overall the Redarc Liberty brake controller works well. Ive only had to stop hard once and Im happy to report I had no sway or misbehaving. I have managed to inadvertently brush the sensitivity control knob, decreasing the sensitivity. Just follow your departure checklist which includes checking the brake sensitivity and you will be fine. My only complaint is the illuminated dial. It just isnt bright enough, or the numbers arent bold or big enough, its hard to see what the sensitivity is set at without getting your face right up next to it. I would recommend this unit to a friend.

Outstanding! 5000 miles and has not. failed me once. I have found setting the controller just under halfway 4 works best for highway and around town. Bumping it to 5-6 is wonderful on mountain passes and keeps both the truck and trailer easy to control. Great product! If I had done just a little more research I would have discovered e-trailer even has a harness for my application and would not built my own. Highly recommend for a Tacoma!

That is super exciting about the mini-home! I wish you the best of luck with the overhaul - if you feel like sending in some pictures when you're done, we'd love to see them :)

The Redarc controller continue to impress me. This last year we went through NYS and the Adirondack Mountains where there are some long and serious downgrades and we also drove in a lot of stop & go traffic and I was always able to get the appropriate level of braking without locking the wheels. This is the best brake controller Ive ever used.

Where is the connector you tried located? I've confirmed that the harness included with the controller is the correct one for the 2023 F-150, so I'm guessing you're not in the right place...

Great! The controller worked perfect and I was able to dial in the exact perfect resistance for the trailer brakes and everything towed very well. Unfortunately we sold our trailer but the brake controller still looks great in the car and I even got a compliment on how Stock or OEM it looked.
Do you have a question about this Trailer Brake Controller?

This has been working perfectly for me. Only issue I had was where I mounted the switch it could get bumped by my knee getting out the car. I 3D printed a small piece to prevent that.
