Tow-Pro Liberty Operation

The dash-mounted knob puts control of your trailer's brakes at your fingertips. In addition to offering fast, simple power adjustment and an easily accessible manual override, it has colored LED signals that let you know what the brake controller is doing at a glance.


Redarc Tow Pro Liberty Calibration

When you are calibrating the brake controller for the first time, the LED lights will signal your progress. To finish setting up the device, you will need to drive your vehicle in a low-traffic area and brake 20 times or so to let the unit learn its orientation and the direction of travel. If your trailer is connected, the LED light will flash green/blue as it processes the information. If there is no trailer connected, the unit will still calibrate, just without the knob lighting up. The knob will stay blue longer as the calibration process gets closer to being done. When the display turns solid blue, initial calibration is complete. The unit will remain calibrated for the next time that you tow. If recalibration is required, it will happen automatically and without LED indication.


Once the brake controller is activated, you can use the knob to set the maximum amount of power that will be applied to your trailer's brakes. Typically, this power is only readjusted when you experience changing road conditions or if you switch over from a heavy, loaded trailer to a much lighter, empty trailer, or vice versa. To get more power to your 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.


Redarc Tow Pro Liberty Manual Override

The Tow-Pro Liberty keeps the manual override within easy reach, great for stopping sway or controlling your trailer's momentum in emergencies. To engage the manual override, just press the control knob. This will activate the trailer's brakes and brake lights without you having to apply the brakes on your tow vehicle, perfect for limiting trailer movement while you're cruising.


Redarc Tow Pro Liberty review

Simple, Out-of-the-Way Installation

Unlike most proportional controllers on the market, the Tow-Pro Liberty has almost no mounting restrictions. It comes in 2 pieces - the main unit and the control knob. Because the only part that you need to be able to access is the control knob, the main unit can be mounted out of sight and out of the way. You don't have to worry about banging your knee on a bulky brake controller or interfering with your vehicle's lower airbags.


Redarc Tow Pro Liberty Dash Mounted Remote Knob

The dash-mounted 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. You can pick up a universal mounting panel (331-TPSI-001 - sold separately) for 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 room behind the dash for the entire knob to install, including the part you don't see!

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' plug-in cable that has to be able to reach between both 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 zip-tie the box 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).


Proportional Braking

What is proportional Braking

The Redarc Tow-Pro Liberty Brake Controller comes equipped with proportional braking to give you the best towing experience. 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.

Video Transcript for Review of Redarc Trailer Brake Controller - Tow Pro Liberty Proportional With Harness - RED82CR

Hi everybody, Andy here with etrailer.com. Let's take a look together at this REDARC Tow-Pro Liberty proportional brake controller with custom wiring harness. Now, this brake controller kit has been designed to fit your 2003 and newer Toyota 4Runner, then your 2003 to 2021 Land Cruiser, then your 2003 and newer Sequoia, then your 2005 to 2015 Tacoma, and then finally, your 2003 to 2014 Tundra. On custom fit parts such as this brake controller kit, I do recommend taking advantage of our vehicle fit guide here at etrailer.com. Simply input the year, make, and model of your vehicle and our fit guide will confirm if this kit will work for you or if we have something comparable that will work for you. Now, this brake controller kit will require minimal dash space in your vehicle and this is gonna be very simple to install and operate.

It's gonna give you a factory look and feel. It's gonna look like it's always belonged installed on your dash or your console, wherever you decide to install this. This brake controller is going to activate your trailer brakes in proportion to your vehicle's braking action. It will automatically adjust the trailer's braking based on the deceleration of your tow vehicle. And this has this control knob, which is really the star of the show here, that's going to mount in your dash or other easily accessible area.

And as you can see you, you are going to receive a selection here of different inserts that's going to allow you to use whichever one's gonna be the best look and the best fit for your particular vehicle, whether you install this in an open blank on your console or your dash, so you're gonna have some options here to choose from. And this is going to allow for quick and easy adjustment of the braking power with just the turn of the dial. It's also going to provide manual override by just pressing the knob to activate. And it's gonna offer you simple diagnostics with the bright colored LED. Now, this main unit here is going to install out of sight, so you're not gonna have to worry about banging your knee anymore on a bulky controller.

You're not gonna have to worry about interference with airbags and other vehicle accessories and, of course, no hard to reach override lever or impossible to read screen. This can be mounted in virtually any position, direction, and angle. And you can securely mount the box using screws that you might have on hand or double-sided tape or cable ties. Those items aren't included, but if you do have those items on hand, you could use one of those options to secure this. However, we also have a mounting kit here from REDARC that is available that is sold separately that you can take a look at.

On your screen, I am including our part number for that mounting kit. You can just take that part number and pop it in the search field of our website. That will take you to that mounting kit. And if you choose to go that way, you can add that to your order. Also, I wanted to mention that there's no complicated wiring. This custom fit wiring harness is going to plug, this end is going to plug into the brake controller and then the other end will plug into your vehicle, so it's basically plug and play, but if you are needing a seven-way plug at the back of your vehicle and you don't have one yet, take a look at the other option that I have there for you. On your screen, we have put together a seven and four-way brake controller installation kit. And if you are in need of that, you can also take a look at that part number that I've provided there for you on your screen. That's going to give you an easy way to add a seven-way to the back of your vehicle while also giving you a four-way so you don't lose that functionality. So this brake controller is gonna be for trailers with up to two axles or four brake assemblies. It is designed for use with electric or electric-over-hydraulic trailer brakes. And let me go ahead and leave you with some measurements here of the brake controller itself. So looking at the overall length, we're sitting right at about four inches. Looking at the overall width, we're sitting at about, pretty close to about 3-1/4 inches, and then the overall height about one inch. Well, I think that's gonna wrap up our look today. I do hope that our time together has been helpful for you. Again, my name is Andy. Thank you for joining me.

2024 Toyota 4Runner

This is a great product and was a perfect fit for my 2024 Toyota 4Runner. The staff at etrailer were very helpful when I had questions and the purchase process and shipping was quick. I would highly recommend etrailer for any of your RV needs.

perfect fit, works great

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:

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.

2012 Jeep Grand Cherokee Overland (5.7 Hemi w/Tow pkg)



by:

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.



by:

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:

Installed perfectly with the factory adapter, I had to solder one wire as my kit was slightly different for my 2015 Tacoma, but worked perfectly pulling a trailer from Ohio to New York. Would not pull a trailer without a break controller as I had zero trailer sway. Also installed the same controller in a 2017 Sequoia, factory kit fit perfectly. Pulled a trailer from Ohio to Kansas and back, again zero trailer sway. This is a great alternative to a factory installed controller.



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



by:

I was surprised how nice this brake controller is - clean install with the unit up under the dash. I installed the knob in one of the 'blanks' in the dash for a really clean look. No banging knees on older-style controllers under the dash. Thanks!



by:

Went together very easily. Looks great in the truck, the knob matches well with the factory controls next to it. The YouTube video: etrailer | Redarc Tow-Pro Liberty Brake Controller Installation - 2022 Chevrolet Colorado by Aiden was a GREAT help. Thanks



by:

Installation was very easy, simple, and clean. Looks very nice. I am very disappointed that nobody makes a switch insert panel for Honda or pretty much anything but Toyota. I haven’t programmed it yet but it looks fairly simple.
