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 dinging 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.


A vehicle-specific wiring harness is available for most newer trucks and SUVs. One end of the custom adapter plugs into your vehicle, and the other end either plugs directly into the controller or will splice to the wiring harness - no need to hardwire to your vehicle. If a custom brake control wiring adapter is not available for your vehicle, you will need a universal wiring harness (RED69FR - sold separately). A 30-amp circuit breaker kit (331-CBK30-EB - sold separately) may also be required for installation.

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.

Yes, if you:

  • Like the look of your vehicle’s interior and don’t want to ruin it with a clunky brake controller
  • Have heard good things about the Redarc Tow-Pro Elite but usually stick to the main roads

No, if you:

  • Are intimidated by pulling panels or drilling into your interior to get this installed
  • Rely on the manual override to feather the brakes if you need to reduce sway or if someone cuts you off
  • Want to see your braking status at a glance - this one can be easy to miss

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: Gary02/27/2023

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



by: Reuben07/24/2022

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: Bobby Q07/25/2022

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: Brad02/25/2024

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: Mike05/06/2023

The controller looks and works great. The colors are very easy to see what the controller is doing. No led colors are displayed when there is not a trailer plug in, so it almost disappears on the dash.
Reason I only gave 4 stars out of 5, like others said, the universal harness should have come with it like it does with the Elite. My truck is older so I needed the universal harness. You should only have to buy one if it is a direct plug and play for newer trucks.

2018 Kia Sorento

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: Dean W04/20/2023

Very clean option for a proportional trailer brake controller. Nothing to knock your knees on and easy to access for extra braking as I mounted it in the dash of my E350.



by: James02/15/2023

Install was quick and easy. The only thing that gave me grief was that darn "Trailer Brake Warning Fault" message that kept displaying on my message information display on dash. After troubleshooting for several days and calling etrailer for assistance with no solution, I tried calling Redarc with the included state-side tech support. The number puts you in touch with an Ausie down under so you have to adjust your call with thier time zone. Turns out, and VERY IMPORTANT,if you are replacing an OEM Trailer Brake Controller already installed in truck. The TBC Controller Brake Module has to be deactivated to make the fault go away. Truck still think it has a TBC and is looking for it. I used Forscan software to deactivated it through the OBDII port.

I love the features of the RedArc Tow Pro Liberty and its ease of use..

2023 Hyundai Palisade

I haven't had the opportunity to install this brake controller yet, but so far I like what I see. Especially the small profile of the controller and the dash knob. I bought this to tow a 17' Casita travel trailer. I am just waiting on the 7-pin tow harness from Hyundai before I can put it all together. The instructions indicate that all of the connections are plug and play, so I anticipate a pretty straightforward install.



by: John03/27/2023
Toyota 4Runner

Installation went just like the video. I needed a break controller on my 4Runner, but didn't like the look or placement of a "stranded" break controller. Redarc Tow-Pro fit and look, or lack of look that I was Looking for. On my 4Runner I did move the factory switch placements around so the searing wheel didn't block my view of the break controler.



by: Sandra04/10/2023
2018 Toyota Highlander

Relatively easy install. I think it would be good if you would update the kit to include a 1 amp diode and instructions to install it. This is to prevent backfeed of electric current from brake controller which causes error issues on the 2018 Toyota Highlander.



by: C White05/02/2023

Great product, shipped fast and I could not be happier with the "from the factory" appearance of the installation. I painted the embossed letters in the switch mounting plate so it would match the other switches. The brake controller works well and it really looks great.



by: Dick03/08/2023
2004 Dodge Ram Pickup

Works great and is out of the way. Just find a place under the dash that is secure and bolt or plastic wire tie it in. I had to buy the universal wiring harness also so I could wire it to my 7 pole. You would think it would come with one but I’m guessing there are many types of wiring for each vehicle manufacturer.



by: Gary04/12/2023
Toyota Highlander

Simple to install. Worked smoothly and is as aggressive as you need. No more knee banger. Unit installed easily out of sight. Control is easy to access on the dash. The Adapter for the blank switch cover is a must for a clean installation on the Toyota Highlander.



by: Tom03/07/2023

I love this brake controller. I put it in my brand new 2023 Silverado 1500. It looks factory the way I installed it. No big bulky controller hanging under the dash. Would highly recommend.



by: Kenneth07/18/2021

Expedited shipping was super fast with no problems. I installed the unit myself and it was fairly simple. I recommend getting the exact fitting wire harness (huge time saver) and I’d recommend getting and exact fit knock out to install the dial in. (Another big time saver). I drilled a hole in my own blank or knock out thingy and I’m pleased with it but it took a little time. I’ve got a 2010 Honda Pilot. Funny thing, after rushing to install the brake controller, our trailer had to go in for repairs before we even completed the transaction. It will be another month before I actually use the brake controller.



by: Keith07/15/2023
2019 Jeep Grand Cherokee

Like the way the main unit is hidden from view. The control knob looks original equipment. Found a place just in front of the gear lever to mount the main unit. Using one original screw and one self tapping. I mounted the control dial adjacent to it. Easy to see and very close to where my right hand rests on the steering wheel. I docked one star because I had to lengthen the 'plug and play' harness by six inches.

2017 Honda Ridgeline

The Redarc controller was very easy to install in my 2017 Honda Ridgeline truck. In fact, it was so easy that I wasn't certain that I had installed it correctly because it didn't light up to acknowledge that it was indeed working. After reviewing the instructions, again, I realized that it was noted that there may not be any lights acknowledging proper install when a trailer wasn't attached but it would go through the setup procedure. When I went to pickup my new tractor and trailer, it lit up and worked like a charm.



by: Robert03/20/2024

Install took about an hour and a half. I have big hands that didn't play well with the room under the dash. The controller didn't go into setup mode until I hooked up the trailer and drove around. Other than that so far so good.



by: Jeff11/07/2023

Clean install. I really like these Redarc controllers. 2021 Nissan NV 3500 Passenger. etrailer kit with controller and wiring adaptor was just the thing. Under dash drill access for mounting the module isn’t ideal, but doable. Great kit and great price. Looks great



by: Robert09/29/2022

I purchased the Redarc Liberty for a new Honda Ridgeline which replaced an F250 with an old technology two dial proportional brake controller. This Redarc not only installed easily and cleanly in the more confined cabin of the Honda, its advanced one dial adjustment makes it more user friendly to adjust, and the settings are easily repeatable. For example, my trailer empty on hardtop gets 4, trailer with tractor 5.5, trailer with 1 yard of gravel a 6.5; on a dirt or gravel road just subtract 1 position on the knob.

The photos reflect my mounting technique which consisted of constructing a small open-back box of 1/4" MDF. The Universal Mounting Panel accessory worked well with the MDF. A coating of textured paint to match the interior makes it look almost OEM. Velcro holds the box securely yet allows for easy removal for whatever reason. The wire tucks neatly between the lower steering wheel valance and the console trim--can't see it even if looking for it, and no holes drilled in the dash.

Overall very happy with this product and with etrailer answering my questions and processing the order quickly.

2014 Subaru Outback Wagon

2019 Outback Limited 3.6
Just completed
installation of Echo stealth hitch, Curt 4 way T connector, 4 to 7 way universal trailer brake controller kit, and Redarc Liberty brake controller.
This was a fun and very straight forward project. The Etrailer videos were awesome.
I took my time and knocked it out a couple of hours over 3 days. Im recently retired so no rush.
While awaiting shipment I poked hole through rubber grommet inside engine bay. I then pushed a 3ft length of 1/4" drip irrigation tubing through to pull future brake controller wires into cabin. I had ordered the Curt 4 way T connector earlier so instalked that as well. Videos were great and made finding plug n play connection super fast and easy.
Once parts arrived, I instalked Echo hitch and universal 7 way adapter kit. I picked up a torque wrench at Harbor Freight for $30 which worked great. I needed one for tightening tugs anyway so it was great timing.
I ran the 7 way wiring down passanger side under plastic shield. It was easier than anticipated and virtually invisible. Most videos show mounting inline fuses near battery. With my 3.6 the passabger side was wide open so I opted to mount the fuses there. This required a trip to Home Depot for an additional 14 ft of 10 guage wire. This was used to run hot 2 wires from 40amp/29amp fuses to battery($9.00). Turns out that the irrigation tubing is the exact size for covering anchor bolts on inline fuse. Probably dont need them but keeps everything safe from accidental arching is crossed.
I taped together the white trailer brake wire running from back and the 20 amp output black wire from 20 amp fuse to the piece of drip tubing I previously pushed through gromnet. I added a touch of white grease and it slid through grommet like butter.
The final day I instalked Redarc controller. Installation is fairly straight forward especially after knocking out the dirty parts of install.
Honestly the most troublesome part of the entire project was identifying the cold brake pedal wire. These wires are minute. The key is having the right tools which I did not. Purchase a hook probe circuit tester and save yourself all the frustration. I watched many videos and there were multiple answers as to which wire is the correct wire. Dont guess or take soneones advice, verify. A hook probe tester like the instalkers use is worth $20. I ended up dropoing by my local uhaul that does custom hitch instalkations. Base labor price $60 which was totally worth it at that point. I saved a lit of $ DIY so I had the pro identify and connect controller to proper brakewure activated when pedal is pressed. I had it all open for him so he only charged me $20. Thank the Lord he was an honest cool guy.
After completing instalkation and powering up system the Redarc had no lights whatsoever. I calked Redarc and they had me check for power at black wire on input side, all good. I then disconbected both sides of controller, multi rmwire side and control knob side. After reinstalling the blue led indicator light fired up. Everything is back in place and working great. I dont have our trailer yet, but purchased a 4 way and 7 way tester and all systems are ready for launch!
I ended up mounting the control knob onto the fuse cover lid on left dashboard. This was just easy and simple. Added some tacky strips to hold cover securly.
This was a fun project and etrailer made it super easy. Items were delivered quickly and great quality. etrailer is my go to stop for everything towing.



by: JDen03/21/2024

I installed this over a year ago in my Honda Pilot. The video was the perfect help. It worked like a charm and like so clean and professional. I could not be happier.

  • I discussed your issue with a one of the training representatives from Redarc and while they have not before seen this issue with an install, he did have an idea of what might be occurring.
