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.


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.


Redarc Tow Pro Liberty Dash Mounted Remote Knob

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!


A vehicle-specific wiring harness (sold separately) is available for most newer trucks and SUVs. One end of the custom adapter plugs into your vehicle, and the other end will either plug directly into the controller or will splice into the included wiring harness - no need to hardwire to your vehicle.


If a custom brake control wiring adapter is not available for your vehicle, you will need a universal wiring harness (RED69FR - sold separately). A 30-amp circuit breaker kit (331-CBK30-EB - sold separately) may also be required for installation.


Note: If you don't already have a 7-way plug at the back of your vehicle, take a look at our exclusive 7- and 4-way brake-control installation kit (ETBC7 - sold separately).


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.

  • Recommended Brake Controller to 2024 Nissan Frontier With Tow Package
    For your 2024 Nissan Frontier I recommend the Redarc Tow-Pro Liberty Brake Controller # RED24FR. I like the Liberty because it is simple, reliable, and looks great in any vehicle. The main unit installs behind the dash, so only the control knob will be visible. The knob controls the braking power and acts as the manual override. It also uses colored LED lights for diagnostics. The # RED39FR wiring harness will plug into the port under the dash you referenced for a plug and play installation.

    Hey Sergi, thanks for reaching out! Go with the etrailer Trailer Hitch Receiver # e55ZR. There are some subtle differences in design but really what the price difference amounts to is the EcoHitch Invisi Trailer Hitch Receiver # 306-X7381 was really the first of it's kind on the market, but then other companies started coming out with their own designs like it and TorkLift/EcoHitch still thinks that their design is much more superior to everything else on the market...which it isn't.

  • Should There Be a Light On the Redarc Tow-Pro Liberty Brake Controller While Driving Without Trailer
    In regards to the Redarc Tow-Pro Liberty Brake Controller part # # RED24FR, the unit should not be illuminated while driving without a trailer. If you press the button while a trailer is not attached you should see a breathing blue light and that simply indicates the controller is in sleep mode. This is further explained in the manual so please give this a look over.

  • 2023 Ford F-350 Having Issues With Electric Over Hydraulic Trailer Brakes
    It is not uncommon for certain factory brake controllers to have issues with electric over hydraulic brakes. This would be the first we have heard of this issue with a 2023 Ford F-350, but it is possible that the brake controller in your ford is simply not compatible with electric over hydraulic brakes. There may be an adapter module available depending on what brand of actuator you have on your trailer so that is one option. If you can tell me the make and model of your actuator I can...

I'd also check that there's not bare or damaged wires touching each other behind the 7-way. From there I'd start to question that the brake controller is properly functioning. You've already...
