Most brake controllers stick out and clutter your cab, but this one keeps things clean and simple. The Redarc Tow-Pro Liberty tucks the main unit out of sight, while the only thing visible is a small knob that blends right into your dash. The control knob measures just 1-7/8" long x 9/16" wide x 3/4" tall, so it looks like it came straight from the factory. You can mount it wherever it’s easiest to reach without taking up knee space or interfering with anything else on the console.
Jerky stops and trailer sway are no fun when towing. The Tow-Pro Liberty’s proportional controller uses an internal 3-axis accelerometer that matches your trailer’s braking power to your own braking input. Whether you’re easing off the pedal or stopping hard, your trailer brakes do the same, keeping everything steady and in sync. It works with electric or electric-over-hydraulic brakes on trailers with up to 2 axles (4 brake assemblies), delivering confident, even braking every time.
Installing a brake controller doesn’t have to mean cutting and splicing wires. This kit comes with a vehicle-specific plug-in harness that snaps right into place for a fast, reliable connection. The main unit can mount anywhere within range of its 3-foot cable to the knob—under trim panels, behind the glove box, or anywhere out of sight. Once connected, calibration happens automatically as you drive and brake normally.
Everything runs through one small knob—adjusting braking power, hitting manual override, and reading color-coded alerts. Turn it clockwise toward 10 for more braking power or counterclockwise toward 0 for less. Pressing the knob activates manual override to steady sway or slow your trailer independently when you need it most. The LED light changes from blue to red as the trailer brakes engage, showing how hard they’re working in real time.
This controller is tested for safety and durability under strict international standards. It meets or exceeds both UNECE R21 and FMVSS 201, ensuring it performs reliably under tough conditions while keeping your interior safe from sharp edges or impact risks. With output rated at 9–16 V and 18 amps continuous (12 V DC max), the Tow-Pro Liberty is built to handle heavy towing without breaking a sweat.

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!

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.

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.

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.
