How to Use Redarc Tow-Pro Liberty

Adjusting the braking settings on the Tow-Pro Liberty is super simple. To get more power output - the maximum amount of power that will be applied to your trailer's brakes - rotate the knob clockwise toward 10. To decrease the power output, rotate it counterclockwise toward 0.


Redarc Tow Pro Liberty Braking Output Red Light

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.


Manual Override

To engage manual override, simply press the control knob. This will activate the trailer's brakes and brake lights independent of your tow vehicle, great for stopping sway or controlling your trailer's momentum in an emergency.


How to Calibrate Redarc Tow-Pro Liberty

When you are calibrating the brake controller for the first time, the LED lights will signal your progress.


Redarc Tow Pro Liberty Dash Mounted Remote Knob

You'll start by braking 20 times or so to let the unit learn its orientation and the direction of travel. You don't need to have a trailer connected for it to calibrate; the only difference is that the knob won't illuminate at all. If your trailer is connected, the LED light will flash green/blue as it calibrates. When the display turns solid blue, initial calibration is complete.


Once done, the unit will remain calibrated. If recalibration is required, it will happen automatically and without LED indication.


How to Install Redarc Tow-Pro Liberty

The Liberty has almost no mounting restrictions. It comes in 2 pieces: the main unit and the control knob. The main unit mounts 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 airbags.


The 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 enough clearance behind the dash for the entire knob to install!


where to install REDARC Tow Pro Liberty on 2023 Jeep Wrangler 4xe

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' cable connecting 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 attach the module to wiring or cables that can shift as you drive!


REDARC Tow Pro Liberty Harness

The included wiring harness hardwires into your vehicle's wiring and then plugs directly into the main unit. For assistance in properly wiring the Tow-Pro Liberty, please refer to the diagrams below:


Redarc Tow Pro Liberty Wiring Diagram

What is Proportional Braking?

What is proportional Braking

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.

  • What Wiring do I Need to get My 2022 Toyota Highlander Ready for Redarc Tow-Pro Brake Controller?
    Hello Dan, We can most definitely get you set up to use your Redarc Tow-Pro Liberty brake controller in your 2022 Toyota Highlander. Since you were looking at the # ETBC7, I’m assuming your Highlander does not have the factory tow package. To equip your vehicle for a brake controller, you’ll first need the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # TK99FR. This is fairly simple to install, with the most challenging part being the removal of some paneling to access...

  • Will the Redarc Tow-Pro Liberty Controller Work with a 2023 Ford Ranger
    Hey Jacques, thanks for reaching out! The Redarc Tow-Pro Liberty # RED52VR will work just fine on your 2023 Ford Ranger, and it will install by splicing into a bundle of wires under your driver side dash. We have a video of this same process of the Prodigy P3 # 90195 on a 2021 Ranger that I'm linking for you to reference, but we don't have anything of the Liberty on a Ranger at this point in time. I'm not sure why we don't have this listed out to fit "with the tow package", but I'll send...

  • Complete Towing Setup With Brake Controller for 2025 Honda Odyssey
    Hi Mike! Do you want a completely hidden hitch or one where only the receiver is visible? The Curt # C64NR you looked at has a concealed cross tube so you will only see the receiver hanging down at the rear. The Hidden Hitch by Draw-Tite # DT76GR will also work and has a completely removable receiver when you aren't towing. If you decide to get the Hidden Hitch you will also need the Quick Links for Safety Cables # RM-910022. The next thing you need is wiring. Curt T-Connector Vehicle...

  • Parts Needed to Install 7-Way and Brake Controller on a 2024 Subaru Crosstrek With Factory 4-Way
    Yes, our 7-Way Kit # ETBC7 will connect into your factory 4-way on your 2024 Subaru Crosstrek. This means you will not have to splice into the tail lights. The kit does include universal wiring for both a charge line and Brake Controller # RED52VR which will require you to connect to the battery and splice into the brake switch since your Crosstrek does not have a factory plug and play option for the brake controller.

  • Recommended Weight Distribution Hitch for 2022 Keystone Springdale Mini 1750RD
    Hey Michelle! There are definitely a lot of different weight distribution hitch (WDH) options out there. The most important thing is to make sure it is properly rated for the tongue weight of your setup. Looking at the specs for the 2022 Keystone Springdale Mini 1750RD it has a dry (unloaded) tongue weight of 520 lbs and a GVWR of 4,400 lbs. Tongue weight is typically 10-15% of the loaded trailer weight so at the high end, fully loaded, you're going to be around 660 lbs. For occasional,...

  • Parts Needed to Add Brake Controller to 2026 Ford Transit T350
    Hi Michael! Do you already have a 7-way on your Transit? If you don't have wiring, you need to start by adding a 4-way with # C56327 (single rear wheel) or # C42MJ (dually). Once you have your 4-way installed you can upgrade it to a 7-way using the # ETBC7. Then for a brake controller, I recommend the Redarc Tow-Pro Liberty Brake Controller # RED52VR. The Liberty is simple, reliable, and installs just about anywhere in the cab. The main unit is hidden and the control knob installs in...

    There is a wiring kit for a brake controller Preston but it's not going to be a plug and play one. The 2025 Toyota Tacoma does not have a plug in brake controller port. Toyota stopped putting them in after the 2023 model. For your Tacoma, I recommend the Redarc Tow-Pro Liberty Brake Controller w/ Universal Wiring Harness item # RED52VR.

There are no custom wiring harnesses for that Workhorse chassis so you will splice in for installation. What are you towing with the Southwind?
