Most brake controllers stick out under the dash, but this one tucks the main unit out of sight behind the trim. All you see is a small knob on the console—just 9/16" wide and 1-7/8" long. It looks like it came from the factory. The knob handles everything: adjusting brake power, hitting manual override, and showing color-coded alerts that shift from blue to red as braking intensity increases. No bulky box, no bumped knees—just a clean, factory-style look that fits anywhere on your dash.
The Tow-Pro Liberty delivers smooth, confident braking for trailers with up to 2 axles (4 brake assemblies). Its internal 3-axis accelerometer senses how hard you’re braking and matches the trailer brakes to your input. Light braking means gentle stops; hard braking means full stopping power. It works with both electric and electric-over-hydraulic setups and outputs 9V–16V at up to 18 amps continuous. The result is balanced, proportional braking that eliminates the push-pull feel and cuts down on wear to both tow vehicle and trailer brakes.
Installing a brake controller doesn’t have to be a project. This one includes a custom plug-in harness that connects directly without cutting or splicing wires. Once you pick a mounting spot for the knob, secure the main box behind the dash using screws, tape, or zip ties. The only limit is the 3-foot cable between them. Calibration happens automatically after about twenty normal brake applications—no special tools or trailer needed—and from there it maintains itself without any extra setup.
When you need instant control—like during a sway event or while easing down a hill—the manual override is right on the knob. A quick press applies the trailer brakes independently of your tow vehicle for better stability and control. The LED indicator gives clear feedback: flashing lights during calibration, blue when ready, and deeper red shades under stronger braking. The system meets UNECE R21 and FMVSS 201 safety standards and runs reliably on 12V DC power, proving itself every time you hitch up and head out.

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.

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.

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.

Works flawlessly. Had a minor installation issue. Research technical support was super in resolving the issue

After a year, still working good. We took the Pathfinder and the camper for a 450-mile round trip last weekend and it is still working as it should. The calibration takes a little longer sometimes when you go from trailer to trailer but Ive never had it not work eventually. It may be due to rust on our hitch or grounding on the car - still 100 satisfied.

It’s been a year and it’s still working well. I was surprised to have it not work after changing the battery but all I needed to do was let the module relearn the same as when it was initially installed. All back to normal.
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.
