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!


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.

My third or fourth etrailer purchase. They have all been exceptional quality with easy to follow installation videos on the website. If any help with fitment or correct model number is necessary help is quick, courteous and efficient. Would give 10 stars if it was an option

This controller tucks out of the way for a nice clean look, all parts were quality stuff! The dash mounted knob looks good as well. The whole experience went very well.

I'm new to RV's so this is my first experience with a brake controller. Also my first purchase from etrailer.com. etrailer.com's website and inventory are impressive. I really like how you can select your specific vehicle so that only parts that work with that vehicle are shown. Having selected my truck first before searching for a controller, I also like the fact that this Redarc controller came with Toyota Tacoma specific wiring as well as the replacement switch labeled "trailer brake" that replaced the open blank button in my truck. The result is that the control dial looks factory installed - very clean, and no box hanging off the bottom of the dash. The written instruction booklet is clear and thorough, and coupled with a youtube video showing how to install this exact product in my Tacoma made installation super straight forward. I'm not that handy and I did it without difficulty. The product is now calibrating as I drive, so I'll update about performance/operation once we haul our RV on a trip.

The hardest part was getting the zip ties tightened around the module without completely removing the trim under the steering wheel. I chose near the shifter for my location so it’s easy to reach but still out of the way.



by:

Install was simple and it doesn't encroach on your leg space other than the manual button. My wife didn't want a brake controller box hanging down on the knee bolster so this is a great alternative for her tahoe.



by:

Installed in a 2015 Chevrolet Express. The installation was pretty straight forward, especially since I'd already done the grunt work of the wiring while waiting for the controller to come in the mail, so it was just connecting 4 wires, mounting the box up under the dash and drilling a couple holes for the dial/light (decided to put it next to the 120AC plug on the dash) and plugging it all in. Still in the market for a trailer, but now I should be ready to go when I find what I'm looking for.



by:

Works great! No more readjusting between hi way and Campground driving. Looks great. Straight forward instruction for installation.



by:

The Dash Knob needs to be redesigned. I broke the lighting tube and will need a new dash knob. I cannot see any light from it so I don't know if the system is working/calibrating. I cannot push the button in so that function is not working. I found a good spot to mount the controller unit under my dash. I did watch your video installing the unit on a Colorado. I have a 2019 Colorado with a trailering package but it did not come with a brake controller.



by:

This is a great product to install Works fantastic in my 2023 Jeep Grand Cherokee Limited the remote switch you can put just about anywhere. I like how you don't have the big old bulky brake controller under your dash.



by:

This is my second trailer brake controller from Redarc with this style. Neither of the vehicles I installed them in came prewired from the factory (2019 Subaru Crosstrek and 1999 Isuzu Amigo). The hardest part of installation for me is locating a place to put the "knob" that is easy to access but out of the way and most importantly doesn't require me to drill holes into hard parts of my vehicles. In both installs I managed to get the knob installed into a blank switch knockout. I run the power directly to the battery and have not had any problems with it turning itself on when needed or causing the battery to drain. This is by far the best looking trailer brake controller on the market that isn't factory installed



by:

I purchased the Redarc Liberty brake controller because I couldn’t find a place to mount my Tekonsha where I wouldn’t bash a knee or shin on it or cover an airbag.
So far, I’m very happy with the Redarc Liberty brake controller; although, I haven’t used it for towing yet, and I’m not sure it is operating properly. Apparently, I should have blue lights while it is learning which way the control unit is oriented but I don’t have blue lights.
Anyway, let me share information on the installation. I purchased the wiring harness for my vehicle, which I highly recommend as it was same cost as the universal harness, and a big time saver. I did not buy the blank switch panel for the switch installation as another reviewer stated he was able to modify the original switch blank. Big mistake, I highly recommend buying the appropriate switch panel for your vehicle. My Toyota blank switch panel was excessively complicated so I had to saw and melt a pile of plastic (see the picture) out of it without damaging the visible portion or the clips which hold it in.
Finding a suitable location to secure the controller up under the dash is a challenge with modern cars. After removing two pieces of plastic trim, I did manage to pull the panel below the steering column far enough out to complete the install. The unit it does look good. Very clean.
We’ll be towing the big trailer next week so I hope it works.

Being new to towing a larger trailer requires research. After doing a lot of it, both through user reviews and manufacturer websites, we landed on the Rearc Liberty Brake Controller for our Tacoma. We have just over 1000 miles towing with this unit. It has performed extremely well. Towing for us includes city, highway, mountains, and even off-road to access our mountain home. Installation was straight forward and the ability to install the controller in virtually any position is an added bonus. I was able to install the dash knob in a blank panel giving the Tacoma a factory appearance, and controller located under drivers seat. I installed this unit on a non tow package Tacoma, so wiring was a bit intimidating at first. But using etrailer’s web site as a reference had everything operational in a couple afternoons. Great product so far and we look for years of use. Highly recommend.



by:

Mounting the brake controller up and out of the way under the dash of my 2023 Tacoma required some thought. I chose to fabricate a bracket from a piece of 3/4" aluminum angle (bolted to the underside of the dash) and anchored the brake controller to it with zip-ties.



by:

This thing is so much better than the old controller I used to use. I like that it lets the break off after you stop moving even if you have your foot on the petal. Smooth breaking response all together. Plus, I was able to install the knob in an unused switch blank in my 2020 Pilot. You do have to be a little crafty to get it to fit there but it is possible.



by:

This brake controller is the best I’ve used so far. It’s compact, comes with the correct vehicle wire harness splice and has been 100% reliable. Thank you!

I’ve found other brake controllers are either unreliable or too bulky. Job well done Redarc!! The safety trailer loads is of utmost importance.

Great controller and helpful service! Take your time installing the control switch in a convenient place. It's small but works well. I love the easy use of manually applying the trailer brakes by pushing the switch. Mounting the control module in a solid place is required. I bolted it to a dash brace and it works well.



by:

A great trailer controller that tucks under the dash!



by:

Installed this in my 4runner that I use to haul several thousand pounds of metal boxes on an aluminum heavy variant tilt deck trailer. Install was fast and easy, the main unit is small and is easily tucked up under the dash. I drilled one small hole and placed the small lighted selector (small blue light) on the key side of the steering wheel area (see pics) and looks like it came factory from the truck. Its sasy to adjust and robust enough that it wont move settings on its own, even in rough off road conditions that a 2WD vehicle cant go. Ive had other controllers in the past but am super happy that I had lucked out and found this proportional one from Redrac with the dash knob.



by:

Haven’t had any issues with the brake control after towing for a year. It’s been a great replacement for the curt Bluetooth controller which didn’t last 2 months because it’s made with cheap plastic and stuck out so far I backed my trailer into it when parking.

This review includes the following items: Item #RED69FR - Wiring Harness, 30A Breaker kit and Item # ETBC7 Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat and Item #RED24FR Controller. I wanted to be sure I had everything. A local place Custom Coach on Pulaski Hwy, Baltimore did a fantastic job on the install, Sorry I can't remember the techs name. I have a 2018 Kia Sorento SX V6, AWD with 4 pin Tow Pkg. car rated for 5k/500# load. Trailer is a 2022 Palomino Real Lite RL-186. I've logged 2 trips so far 1 to NYS mostly highway and to Cass, West Virginia area. The controller adapted quickly, I went to a '5' to a '4' setting even in the mountains it was smooth no jerking. The one picture shows installation ubder the dash totally out of the way. It works great!



by:

The brake controller was not difficult to install.
I like the fact of controller is in dash area of vehicle with just one control knob shown. Shipping was fast and all items are as described.
Thank you

  • 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.

  • 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.

  • 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.

  • 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.
