Mount the control knob of this proportional brake controller on your dash for a factory look, and install the main unit out of sight behind the dash with the included wiring harness. Control your braking power with the turn of a dial.

Specs:
The Redarc Tow-Pro Liberty Brake Controller comes equipped with proportional braking to give you the best towing experience. Proportional braking means that your trailer brakes mimic your tow vehicle's brakes. If you slam on the brakes in your vehicle, your trailer brakes will activate with the same intensity; if you brake lightly, your trailer brakes lightly too. The trailer's braking is in proportion to your vehicle's braking. This saves wear and tear on the tires and the brakes on both your vehicle and trailer.
The Tow-Pro Liberty uses an internal 3-axis accelerometer to sense how your vehicle is braking so it can send the right amount of braking power to your trailer. It measures the inertia of your tow vehicle and activates the trailer's brakes to slow at the same rate. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.
The dash-mounted knob puts control of your trailer's brakes at your fingertips. In addition to offering fast, simple power adjustment and an easily accessible manual override, it has colored LED signals that let you know what the brake controller is doing at a glance.
When you are calibrating the brake controller for the first time, the LED lights will signal your progress. To finish setting up the device, you will need to drive your vehicle in a low-traffic area and brake 20 times or so to let the unit learn its orientation and the direction of travel. If your trailer is connected, the LED light will flash green/blue as it processes the information. If there is no trailer connected, the unit will still calibrate, just without the knob lighting up. The knob will stay blue longer as the calibration process gets closer to being done. When the display turns solid blue, initial calibration is complete. The unit will remain calibrated for the next time that you tow. If recalibration is required, it will happen automatically and without LED indication.
Once the brake controller is activated, you can use the knob to set the maximum amount of power that will be applied to your trailer's brakes. Typically, this power is only readjusted when you experience changing road conditions or if you switch over from a heavy, loaded trailer to a much lighter, empty trailer, or vice versa. To get more power to your brakes, rotate the knob clockwise toward 10. To decrease the power output, rotate it counterclockwise toward 0.
When you apply the tow vehicle's brakes, the knob will change from blue to red to signal that the trailer brakes are being activated. The higher the braking power output, the deeper the red that you will see.
The Tow-Pro Liberty keeps the manual override within easy reach, great for stopping sway or controlling your trailer's momentum in emergencies. To engage the manual override, just press the control knob. This will activate the trailer's brakes and brake lights without you having to apply the brakes on your tow vehicle, perfect for limiting trailer movement while you're cruising.
Unlike most proportional controllers on the market, the Tow-Pro Liberty has almost no mounting restrictions. It comes in 2 pieces - the main unit and the control knob. Because the only part that you need to be able to access is the control knob, the main unit can be mounted out of sight and out of the way. You don't have to worry about dinging your knee on a bulky brake controller or interfering with your vehicle's lower airbags.
The dash-mounted control knob can be installed in any convenient spot that's easy for you to see and access. This can be a blank switch panel, an open spot on your center console, or wherever there's space on your dashboard. A universal mounting panel is included to ensure a clean, from-the-factory look. Custom-fit panels are available for certain vehicles as well. Before you do any drilling, be sure there's room behind the dash for the entire knob to install, including the part you don't see!
Once you've decided where you want to put the control knob, you'll need to find a good place to install the main unit. Your only restriction is the 3' plug-in cable that has to be able to reach between both the main unit and the control knob. Securely mount the box using screws, double-sided tape, or zip-ties (not included). A mounting kit (RE67FR - sold separately) is also available for the Tow-Pro Liberty. Do not zip-tie the box to wiring or cables that can shift as you drive.
The included wiring harness hardwires into your vehicle's wiring and then plugs directly into the main unit. You can also use a vehicle-specific wiring harness (sold separately) to cut down on installation time. These harnesses are available for most newer trucks and SUVs. One end of the custom harness will plug into your vehicle, and the other end will hardwire onto the Tow-Pro harness that plugs into the main unit.
For assistance in properly wiring the Tow-Pro Liberty, please refer to the diagrams below:
See etrailer.com's exclusive 7- and 4-way brake-control installation kit (ETBC7 - sold separately) if you don't already have a 7-way plug at the back of your vehicle.
Note: A 30-amp circuit breaker kit (331-CBK30-EB - sold separately) may also be required for installation.

Mount the control knob of this proportional brake controller on your dash for a factory look, and install the main unit out of sight behind the dash with the included wiring harness. Control your braking power with the turn of a dial.Install was simple and it doesn't encroach on your leg space other than the manual button. My wife didn't want a brake controller box hanging down on the knee bolster so this is a great alternative for her tahoe.
Installed perfectly with the factory adapter, I had to solder one wire as my kit was slightly different for my 2015 Tacoma, but worked perfectly pulling a trailer from Ohio to New York. Would not pull a trailer without a break controller as I had zero trailer sway. Also installed the same controller in a 2017 Sequoia, factory kit fit perfectly. Pulled a trailer from Ohio to Kansas and back, again zero trailer sway. This is a great alternative to a factory installed controller.

Kevin, I am so happy to hear you had a great experience with the Red Arc brake controller. This one of our favorites too.
Awesome product! I installed this in my 2021 Subaru Outback Onyx XT. I mounted it in my spare tire wheel well (see pictures). Full Disclosure: The way I installed it took a lot of effort and required some custom fabrication and cable routing. I use two waterproof 30amp blade fuse holders, one independently powers the trailer 7-Pin and the other independently powers the Brake Controller (both power cables run together from the engine compartment back to the trailer hitch harness (note that I previously installed the OEM trailer Hitch Mount w/OEM harness, and a custom touch for the 7-pin upgrade). From the Redarc dash knob I ran a 12ft Cat 6E Shielded Plenum Rated Premium Custom Ethernet Patch Cable to the controller and tapped into the third brake-light circuit using Redarc's Encapsulated Power Diode - you absolutely need this diode. I could not be happier with the form, fit and function of this product and enjoy showing off my custom installation whenever the topic comes up >Big Smile<. Also, I plan to add a video to my Stickler-ish channel soon.
The Redarc brake controller has continued to perform well. Super easy installation, simple operation, and consistent performance make this a great choice for any vehicle.
Relatively easy install on my 2013 Toyota Prius V. Works great too. Got brake signal from small blue wire (22Ga??) behind panel at driver's left foot.
Install was a little harder than I’d wish but results are fantastic I installed it into a 2016 Vw Tourage TDI and used the harness in the pic from my vw dealer
Received as described. Probably works as it should but couldn't get the unit to calibrate. Later found out that the unit doesn't calibrate to some electric/hydraulic brake systems due to the lag in response time. They recommend calibrating it to an all electric brake system prior to use on an Electric/hydraulic system. This just added another layer to what I was doing. See Manufactures comments below that I found through troubleshooting research.
"REDARC engineers are currently exploring potential upgrades to the Tow-Pro to allow calibration to work with trailers using these Electric / Hydraulic systems. In the meantime, the current solution to this issue is to calibrate the Tow-Pro installation using a trailer with Standard Electric Brakes first."
A 5 stars service and delivery. Canadien custom add 40$ CAD. On my 2023 Honda Passport TrailSport the break connector is about 3 inch above the OBD2 connector. You will need the universal connector sold by etrailer. The coller code are not the same has the one l got from Honda Canada. I followed the instructions and it went well. The controller was place behind the plastic cover left of the parking break pedal. Thank you and have fun.
I put this on a 1998 Chevy 2500 long bed. I like that when you push the button to test your brakes. It applies the brakes at what you have it set at. I like the factory look and it was easy to install.
Easy to install in my Subaru Ascent. Works well
Redarc installed easily under dash all you see is a lil knob. Works great. Usually a fine tune on the knob depending what I’m pulling but amazing. Would not go back to a traditional controller.
Installed on my 2019 Ranger, followed the video instructions for the Elite tow pro. The install went smooth, no glitches. Brake controller is user friendly and easy to adjust.
Work perfect and easy installation on my 2022 Canyon AT4.
Thanks to the Etrailer team!
It's such a clean looking install. Works great. The light could be a little brighter.
Always a pleasure to do business with etrailer. Parts are always on time and the staff is super helpful.
Easy to install out of way and still reach activation button.2017 wrangler
Easy install, and I'm not that mechanically inclined. Works great for towning my tractor. Thanks for the help Etrailer.
Remove center console, mount remote, extend custom ethernet under carpet to rear fuse panel, add fused breakers, locate center stoplamp wire in trunk and add diode to Redarc stoplamp control wire to protect vehicle lighting controller, mount 7 way connector after installing trailer lighting controller. System works fantastic towing 5,000 lb load.
I haven’t had a chance too test it on the road with a trailer yet but it earned 5 stars for the clean look and simple installation. It fit the factory blank switch location on my 2004 Honda Pilot with some minor modifications. I don’t even notice it when I’m driving without a trailer (it doesn’t light up unless a trailer is connected).
The controller arrived as described. Research on the front end prepares me for the self install, which was very simple with a few basic tools. Have an idea of where you want the control knob to be, double check space (account for the switch on the back side of the panel).
Helpful hint - The grey grommet can be used to locate the smaller hole needed, this saves time and ensures correct placement, just requires a smaller drill bit (make sure not to elongate the grommet hole).
I think it’s The Best controller I’ve ever used
I was replacing an older style controller. The wiring was just about the same and was very easy to adapt with soldered connections and shrink tube. The control knob turned out very factory looking with the proper dash insert. Just tried out once with the tailer but really works well. Definitely recommend!!
Easy install. Works as it should.
Be very careful with the nut for the button. Cross threaded mine, ruining the button now 4 weeks to get a new one for $[XX]. The holes for install listed as 3/8 and 1/8 but really a bit larger. Hope it works when ever I eventually get this installed.
Very good unit. Installed main unit under the dash and the knob control fit right into one blank switch spot on my 2010 Tacoma. It works good and looks like a factory unit.
