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!


Custom wiring harness of Redarc Tow Pro Liberty

Then plug the custom-fit harness right into your vehicle and the brake controller and you're done!


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 controller installation kit (ETBC7 - sold separately).


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.

  • 2018 Ram 1500 Connector Location for Brake Controller
    The install the Redarc Tow-Pro Elite # RED44FR using the Wiring Adapter # 331-TPH-020 for your 2018 Ram 1500 you'll need to find the vehicle-side connector for the adapter. This will be located up under your driver's side dash to the right of the steering column. Sometimes these connectors can be hidden really well and I've seen people pull down that fascia piece below their steering wheel to make locating it easier. Once you can find that connector though the rest is just plug and play...

  • Installing Redarc Tow Pro Liberty Brake Controller on 2021 Ram 1500
    We don't have a video for the install of the Redarc # RED24FR Liberty brake controller on a 2021 Ram 1500, but I'd be happy to link to a video for a different brake controller that shows where the # 331-TPH-020 wiring harness plugs in. The harness plugs into the connector located above where the driver's right knee would be, as shown at the 1:18 minute mark in the linked video.

  • Recommended Trailer Brake Controller For a 2022 Ram 2500
    I recommend the Redarc Tow-Pro Elite Brake Controller # RED44FR for your 2022 Ram 2500. This will connect with the Plug and Play Wiring Harness # 331-TPH-020 to the under dash connector. I prefer this controller over the Curt Echo # C27JR with the Adapter # C51458 and factory options as it gives you more adjustability and is easily controlled with the dash mounted control knob. While the Curt is easy to install you have to control everything from your smart phone including adjusting braking...

  • Will A Redarc Tow Pro Liberty Require A Visit To The Ram Dealership To Install In A 2022 Ram 1500
    No, once you have the Redarc Tow-Pro Liberty Brake Controller # RED24FR wired up in your 2022 Ram 1500 all you'll need to do is calibrate the controller. This can be done by simply driving around and and then coming to a complete stop. The control knob of the unit will blink blue and green during this process and will eventually be solid blue when fully calibrated. I've installed a few of these myself and the unit has typically calibrated for me within just a few minutes. I recommend...

  • Can 2022 Ram 2500 Power Wagon Use Aftermarket Brake Controller
    Hey Dave! An aftermarket brake controller can definitely be used on your 2022 Ram 2500. The Redarc Tow-Pro Liberty Brake Controller # RED87CR you looked at is what I recommend. The main unit on the Liberty installs behind the dash so only the knob is visible in the cab. This means it isn't taking up space and has a nice, clean OEM look. This version of the Liberty includes a custom wiring harness for a plug and play installation. What kind of trailer will you be towing?

    Hello again Brett, Congrats on the new truck! I am pretty sure that the connector on the back of your 2024 Ram 1500 Classic is a 7-way connector, you are supposed to count all the slots and include the piece in the middle.

What I did find for your vehicle is the Redarc Tow-Pro # RED87CR that does have a plug and play harness for your vehicle. I do not see a plug and play option for the controller mentioned.

  • Troubleshooting Trailer Brakes Locking Up w/a Factory Brake Controller on a Ram Truck
    Hey Chris, welcome back. It's either a faulty factory brake controller or an issue with your trailer's brakes. Seeing as how they are responding normally with the manual override pressed I would lean towards it being the factory controller. I don't have anyway to test it or troubleshoot it but a quick way to figure out if it's the problem is to hook your horse trailer up to another vehicle and see if the brakes work like they're supposed to. If it's the trailer, then I would start by...

  • What Does Blue LED Mean For Redarc Tow Pro Liberty Brake Controller?
    Hello Rob, thanks for reaching out. So it is normal for the Redarc Liberty controller to have a blue light when the trailer is not hooked up. This just means it isn't detecting trailer brakes. If you used a custom plug-and-play harness, I would have no reason to assume the controller is not working correctly since problems with the factory connections are very rare. Still, the best way to confirm this is by hooking up the trailer and checking.
