Bulky brake controllers take up knee room and never look quite right. The Tow-Pro Liberty hides the main unit behind the dash, leaving only a small knob on display—just 1-7/8" long and 9/16" wide. The clean setup blends in like a factory switch and keeps everything out of the way. That single knob handles brake power adjustment, manual override, and LED status signals so you can fine-tune braking without cluttering your interior.
With proportional braking, your trailer reacts exactly how you brake—no push or jerk, just steady deceleration. An internal 3-axis accelerometer measures motion and matches braking force for trailers with up to 2 axles (4 brake assemblies). Whether your setup uses electric or electric-over-hydraulic brakes, it keeps everything balanced and smooth. The result is safer towing and less wear on tires and pads.
Hardwiring a brake controller can be a hassle, but here it’s plug-and-play. The included custom harness connects directly to the controller and vehicle port—no splicing needed. A universal mounting panel is also included for a clean finish. The main unit secures anywhere within reach of the 3' cable using screws, tape, or zip ties, making installation quick and tidy.
Getting set up is straightforward—just drive normally while braking about twenty times and the Tow-Pro Liberty learns its orientation automatically. You don’t even need a trailer connected for calibration. LED lights guide you through setup until it shows solid blue for ready status. After that, it stays calibrated on its own, quietly adjusting whenever needed without extra steps.
The Liberty isn’t just compact—it’s engineered for safety inside the cab. It meets or exceeds UNECE R21 and FMVSS 201 standards for crash safety and durability. With an output current rating of 18 amps continuous and operating range of 9–16 volts DC, it’s built to handle demanding towing conditions with consistent performance every trip.

Thanks for sharing all the details David! You and your son did a great job finding that steel brace and getting the brake controller tucked securely out of the way. That's one of my favorite things about the Redarc setup, once everything is installed, you really only see the control knob. I'm also glad our team was able to get that damaged knob taken care of quickly for you. Don't worry about forgetting the pictures, sometimes you're too busy getting the job done and admiring the work!
