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...

  • Availability of Hitch and Wiring for 2025 Toyota RAV4 Hybrid XLE Premium
    Hi John; we actually have both a hitch and wiring available for your 2025 Toyota RAV4 Hybrid XLE Premium. I recommend the following: -etrailer Trailer Hitch Receiver # e23ZR OR -Oris Hitches Detachable Hitch # TS66VR -Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56434 The etrailer hitch is my go to for the RAV4. It has a concealed cross tube so only the receiver will be visible at the rear. It also comes with a unique matte black finish. If you would...

  • Recommended Trailer Hitch Receiver and Wiring for 2025 Subaru Forester Towing Trailer
    Hi Jack; for your 2025 Forester I recommend the etrailer # e83ZR. This is a Class III hitch with a 2" receiver and bolt-on installation. It features a matte black finish which gives it an OEM look and helps hide dirt and scratches. The hitch also comes with a limited lifetime warranty. For wiring you can use the Curt # C56040. This plugs into the connection point in your rear cargo area and will give you a 4-way to power your trailer's signal lights. If you have brakes and need a 7-way...

  • 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...

  • Difference Between Prodigy P2 and Redarc Tow Pro Liberty Brake Controller 2011 Toyota Sequoia
    The braking is going to be about the exact same between the Prodigy P2 part # 90885 and the Redarc Tow Pro Liberty part # RED52VR. The main difference will be that the Redarc only puts a small know on your dash and the P2 is a traditional brake controller that is much bigger. To install either controller you'd need the install harness part # 3040-P. For how much cleaner of an install the Redarc provides that would be the route I would go with. For tow mirrors the K-Source set part # KS81300...

  • Troubleshooting No Power To Trailer Brakes with Redarc Tow-Pro Brake Controller
    The best way to test your Redarc Tow-Pro Elite # RED44FR or Liberty # RED52VR brake controller is by cutting the blue wire coming out of it about 6" away from the controller and using a circuit tester to make sure power is coming out of the controller and going towards your trailer brakes. Try using your manual override by pushing the button to send power on that blue wire and you can verify this function. If you do get power coming out of the controller then you have an issue with the...

  • 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...

  • Does the 2025 Jeep Grand Cherokee Have a Plug and Play Adapter for a Brake Controller?
    Hey Dale! Sorry to say but they stopped putting the brake controller adapter plugs in the Jeep Grand Cherokees a few years back. 2020 was the last model year they included them. The Curt Echo item # C51180 is going to be the only plug and play option. It will attach to your Jeep's 7-way and be controlled through an app on your phone. If you do end up using a traditional brake controller, the Redarc Tow-Pro Liberty Brake Controller w/ Universal Wiring Harness item # RED52VR is the way...

  • Does The 2019 Toyota Tundra Allow For Plug and Play Trailer Brake Controller?
    If your 2019 Toyota Tundra includes the factory trailer wiring for a trailer it will have a connector under the dash for a Trailer Brake Controller # RED72CR. This Controller # RED72CR does come with the connector for this application. The small connector is taped into the harness behind the left side kick panel. If you do not have the factory trailer wiring you will want our Wiring Kit # ETBC7, a Brake Controller # RED52VR and a 4-Way # HM11141835.

  • Do 2024 Kia Telluride's Come With A Trailer Hitch And Wiring Already Included
    Kia Tellurides are in our install shop all the time for hitch and wiring installs since Kia typically will not install them at the factory. Manufacturers use "tow package" as a buzz word to charge you more typically so you'll want to get explicit descriptions of what is included with the vehicle. If it doesn't come with a trailer hitch then you can install the Curt Trailer Hitch Receiver # C13420. For wiring you would first need to install a 4-pole wire harness like the Curt Powered Tail...

  • Recommended Trailer Brake Controller For a 2011 Chevrolet Silverado 1500 With Factory 7-Way
    I recommend installing the Redarc Tow-Pro Liberty Brake Controller # RED52VR on your 2011 Chevrolet Silverado 1500. This controller is proportional and takes up much less room than the Dexter Predator DX2 Trailer Brake Controller # 58-8 you found. This will make is easier to reach and give you a much cleaner look with the brake controller. I have linked an installation video below for the Tekonsha Prodigy P3 Trailer Brake Controller # 90195 that will accurately walk you through all the...

  • 7-Way and Brake Controller Recommendation for 2008 Volvo XC90 with 4-Way
    Hey John, so the # ETBC7 that you referenced is the correct kit to convert your 4-way to a 7-way and wire in a brake controller so you are on the right track. So then for a brake controller I really like the Redarc Tow Pro Liberty part # RED52VR which only puts a small knob on the dash of your vehicle and uses an internal sensor to determine how hard to apply the trailer brakes.

  • Parts Needed to Add Electric Brakes to ShoreLand'r Boat Trailer
    Hey Ryan! We don't have a way to identify your axle using the VIN so you will have to check and see what axle you have before we can find the right parts. I would start by checking the axle tag. It may have the capacity listed or, at least a serial number the axle manufacturer could use to identify it. If not, you will need to check and see what bearings you have. The part numbers may be stamped in the side or you can measure the inner diameter with a digital caliper # PTW80157. If you...

  • Will Hopkins Multi-Tow 7-Way Blade and 4-Way Flat Trailer Connector Fit 2022 Toyota Tacoma
    Hello again Mark; you can make the # HM11141144 work with your 2022 Tacoma but you will need additional parts since this is simply the connector and a 7-way pigtail. You will also need to cut off the end of your existing 4-way to hardwire it to the pigtail. In addition to the connector you need the Wiring Kit for 2, 4, 6, and 8 Brake Electric Trailer Brake Controllers # 5506. If you don't have the factory cutout you will also need the Replacement Mounting Bracket for Hopkins 7- and 4-Pole...

    Hey Larry, Yep, The Redarc Tow-Pro Liberty # RED52VR will fit your 2004 Chevy Suburban. You can probably reuse your existing harness going to your current controller, but I'll need to know the brand of your current controller. You'll need one of the following adapters based on your current controller brand: Curt controller currently # 331-TPH-019 Tekonsha controller currently # 331-TPH-017 Hopkins controller currently # 331-TPH-018 With any of these harnesses, you'll just unplug...

    Hey Steven! I'm happy to report that the Redarc Tow-Pro Liberty Brake Controller # RED52VR will fit your 2017 Colorado. Sometimes when there is no custom wiring harness our fitguide picks up vehicles and says it is not a fit. I apologize for any confusion. Realistically, any brake controller fits any vehicle with a 7-way installed. The Liberty is my favorite brake controller and a great choice for your truck. This version comes with the universal wiring harness so you will splice it into...

  • Brake Controller Recommendation for 2022 Hyundai Santa Cruz Premium with 4-Way
    Hey Karen, so your 2022 Hyundai Santa Cruz Premium does have the tow package based on what you have mentioned. So what you need to convert your 4-way to a 7-way and install a brake controller as easily as possible is the Curt 7-way kit part # C68JR which installs without requiring any extensive wiring. Then for a brake controller I really like the Redarc Tow Pro Liberty part number # RED52VR which gives you a proportional brake controller that only puts a small knob on the vehicle dash....

  • 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.

  • Is There A Plug-And-Play Wire Harness For A Redarc Tow-Pro Liberty In A 2025 Honda Passport
    Hey Paul, Redarc unfortunately doesn't offer a plug-and-play wire harness for the Honda Passport but you could splice their included universal wire harness from the # RED52VR to Curt's # C51392. You'll just need to cut off the black connector and use butt connectors # 224775 to connect to the wires between the two harnesses. The harnesses both follow the same wiring code so you can match color for color.
