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!

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!


Once you have the controller mounted in your cab, just plug the custom-fit adapter directly into your vehicle's built-in brake control wiring harness. The other end plugs into the brake controller. No hardwiring needed!


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.

  • Best Brake Controller w/ Plug and Play Adapter for a 2019 Toyota Tacoma
    Hey David! There's no difference other than the sale on the Redarc Tow-Pro Liberty Brake Controller w/ Custom Harness -item # RED72CR or item # RED68CR. Both of these include the Tow-Pro Liberty and the plug and play adapter you'll need for your 2019 Toyota Tacoma. Probably doesn't need to be said, but I recommend going with the one on sale. The correct dash insert for your Tacoma is going to be the Mounting Panel for Redarc Tow-Pro Trailer Brake Controller item # 331-TPSI-002. This one...

  • Which is Better for 2023 Toyota Tacoma Redarc Tow Pro Liberty or Elite
    Hey Rob, yes the Redarc Tow Pro Liberty part # RED72CR that fits your 2023 Toyota Tacoma TRD would work great for you. Normally a proportional brake controller is the absolute best for on-road applications but isn't ideal in off-road conditions but what you mentioned would not be quite off-road enough to require a time-delayed feature like what the # RED42CR that also fits your truck provides. The reason being that proportional brake controllers get confused by the inertia changes from...

  • Brake Controller Recommendation for 2015 Toyota Tundra
    Hey Andrew, yes the Redarc Tow Pro Liberty part # RED72CR is a fit for your 2015 Toyota Tundra with the factory tow package and is a really great option. There is a port under your dash that the included custom harness is designed to fit. It only puts a small knob on the dash of your truck which is the most minimalistic option we have. This is my favorite brake controller to recommend because of that and how well it performs. Does that sound like something you'd like? This would be a big...

  • Recommended Brake Controller for a 2017 Toyota Tundra w/ the Factory Tow Package
    Yes, you can Dave! The best option to add a brake controller, with a plug in adapter, to your 2017 Toyota Tundra is to use the Redarc Tow-Pro Liberty Brake Controller w/ Custom Harness item # RED72CR. The Tow-Pro Liberty item # RED72CR is a proportional brake controller that automatically adjusts your trailer's braking based on the deceleration of your Tundra. The Liberty has a unique installation method where the main unit is concealed behind your dash and the only part visible is the...

  • Which Redarc Tow-Pro Liberty for 2020 Toyota Tacoma SR
    Hi Gonazlo; the easiest thing to do is check to see if you have the factory tow port under your dash. I attached an installation video on a 2023 Tacoma below so you can see where to look. If you have the tow port with a factory 7-way at the rear of the truck you can use the # RED72CR. If you do not have a factory tow port and have an aftermarket 7-way added to the truck you need the # RED52VR instead.

  • Recommended Redarc Trailer Brake Controller Kit For A 2021 Toyota Tacoma
    Hey Lucas, It looks like both the Redarc # RED72CR and # RED68CR are going to include the same wire harness # RED99FR, but the # RED72CR is also going to include some mounting panels to make mounting the control knob into your dash easier so I'd go with it over the # RED68CR. I've attached a short video below Ryan made when he installed this brake controller in a 2023 model for some helpful tips on the installation process.

  • Correct Redarc Tow-Pro Liberty With Wiring Harness for 2015 Toyota Tundra
    Hi Sonny; assuming you already have a factory 7-way the Redarc Tow-Pro Liberty Brake Controller w/ Custom Harness # RED72CR is the correct part for your 2015 Toyota Tundra. This comes with the wiring harness made to fit the factory tow port on your truck so you won't need anything else for a plug and play installation.

  • 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.
