Traditional brake controllers can clutter your cabin and bump your knees, but this one hides the main unit out of sight. The Redarc Tow-Pro Liberty uses a small dash knob—only 1-7/8" long and 9/16" wide—with the rest of the system tucked behind the dash. It looks clean and factory-style while keeping safety clearances around airbags. The knob handles power adjustment, manual override, and LED alerts, so you get full control without any bulky box in view.

Installing a brake controller doesn’t need to be complicated. The included custom harness plugs directly into your vehicle’s tow port for a true plug-and-play setup. One reviewer noted the harness fit perfectly and even came with a 2D drilling diagram for easy placement of the knob. With roughly 3 feet of cable between the control knob and module, you have flexibility to mount everything where it fits best—no cutting or extra wiring needed.


Towing feels safer and more predictable with proportional braking. The Tow-Pro Liberty’s built-in 3-axis accelerometer matches trailer brake pressure to your own braking intensity, eliminating that push-pull lurch at stops. It supports trailers with up to 2 axles (4 brake assemblies) and works with both electric and electric-over-hydraulic systems. The result is even braking, less wear on tires and pads, and better confidence every time you slow down.
You always know what’s happening thanks to color cues on the knob. When you hit the brakes, the light shifts from blue to red as power increases, showing exactly how much braking force is being applied. During setup or calibration, flashing green and blue lights guide you through each step until it turns solid blue—then you’re ready to tow.

The Tow-Pro Liberty meets both UNECE R21 and FMVSS 201 safety regulations for sustainability and crash performance. It delivers up to 18 amps continuous output across a 9V–16V range and carries a 2-year warranty. Once installed, calibration happens automatically—just drive normally while it learns its orientation—and then it stays ready for every trip ahead.

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.

Better than my old brake controller that was screwed into the bottom of the dash

Glad the install was nice and easy, Christine! It definitely looks factory as I don't think I would have seen it if I didn't know what I was looking at! ^___^ What did you install this in? I can sometimes recognize the dash, but I couldn't in this case.

That's really awesome to hear. What are you planning to pull with your Frontier?

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.

Install looks great Johnny! Redarc is definitely my go to for brake controllers. What are you towing that you needed to add the controller?

Using that 4WD switch blank is such a good move, it looks like it came that way from the factory. The install looks awesome Joe. What camper are you pulling?

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!

You definitely found the perfect spot for the knob, Michael! If you ever do need to tow a trailer, you will be more than ready to!

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.

Looks awesome! And that's a nice note about the light to keep in mind, too :)

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.
