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!


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' 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.

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:

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



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.



by:

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.

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:

Harness does exactly what it is supposed to do, connection from Redarc TowPro Elite controller into 2021 Ram Rebel factory harness. Tested all wires on bench prior to installation and everything checked out, and no loose terminal ends in cheap connector here at all.



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



by:

Your sales/service rep failed to tell me that in addition to the Tacoma specific wire harness that I would need the Bezel for the dash to hold the adjustment knob. Delayed my installation and I wasn’t able to pick up my trailer. I suggest you add the bezel to the picture on the website.



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:

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.



by:

A major upgrade from the old brake controller. Great price and quick delivery



by:

I had a cheap brake controller made by CURT. It lacked the manual on it and it was causing my brakes to lock up on the left side of my camper. We found this out going down a mountain pass so it was a little alarming. This brake controller is amazing and I love it so much. Being able to tune it activated and have constant feedback on whether it's working or not is awesome. I highly recommend this. It's perfect for me.



by:

I saw this setup and tried it. I usually have the tekonsha type. Happy w tekonsha. But I do like the integration of this controller. Simple install w provided parts. It also provides an adapter for wiring to your vehicle. I had a spot in my van that I was able to use for mounting. Very clean and factory look. You won’t hit your leg or knee on anything.



by:

After 9 camping trips with my trailer, the brake system is working well.
The installation is super simple with its multi-directional mounting system. Great!



by:

Works great, install instructions way too small for me to see, so I watched video on YouTube on how to install. If not for the videos I couldn’t have installed it!



by:

Just installed the system and can’t wait to try it out! The most difficult part was determining where I wanted the control knob and dealing with the OEM dash component getting in the way of where I wanted it. I appreciate the sophistication and simplicity of the system.

  • Recommended Brake Controller For A 2023 Toyota Tacoma
    Out of all the brake controllers that we offer for your 2023 Toyota Tacoma I recommend the Redarc Tow-Pro Liberty Brake Controller # RED24FR.

  • Will The Facotry Brake Controller In A 2022 Ram 3500 Work With A Titan BrakeRite EOH Actuator
    Dexter makes module adapters to connect the BrakeRite # DX82KR to Ford and Chevy OEM controllers, but unfortunately does not for Ram so you'll need to install an aftermarket EOH brake controller. The OEM module adapters typically have a delayed response time as well so it's honestly better to go with an aftermarket option to avoid this issue. For your 2022 Ram 3500 I recommend the Redarc Tow-Pro Elite Brake Controller # RED44FR along with the Redarc Plug-and-Play Wiring Harness for Tow-Pro...

  • OEM vs. Aftermarket Brake Controller for 2018 Ram 1500 Tradesman
    I doubt you'd be able to increase the asking price of your 2018 Ram Tradesman if you installed the OEM brake controller but I would think that it could only help in selling process to be able to say that option is on the truck. The truck market is pretty crazy though so I doubt you'd have any trouble selling the truck either way and will probably be able to ask a premium price. If you wanted the best function and safety though you really can't beat aftermarket brake controllers like the...

  • Determining A Compatible Trailer Weight For A 2016 Ram 1500 Rebel And Parts Needed To Safely Tow
    You'll first need to ensure that the trailer you're buying falls within the towing capacity of your 2016 Ram 1500 Rebel. This can typically be found in your owner's manual or by subtracting the vehicle weight (GVWR) (including your passengers and anything else loaded in it) from your vehicle's Gross Combined Weight Rating (GCWR). This will give you the max loaded trailer weight that your vehicle can tow. For example, if your GCWR is 13,000lbs, and I use a GVWR of 6,500lbs as a conservative...

    According to my research, the factory controller will indeed need disconnecting before you install the aftermarket controller. Before disconnecting the ITBC (Ram-speak for the factory brake controller), you'll need to get the computer flashed at the dealer so that disconnecting the controller doesn't set off warning lamps/buzzers. I was told that the aftermarket controller would not work with the factory controller still installed. For your Tow Pro Elite, you'll also need the # 331-TPH-020...
