This is one of our favorite brake controllers, with flawless braking and a tiny dash knob that looks like it came straight from the factory. It's so easy to adjust your settings or activate manual override.

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.
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.
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.
When you are calibrating the brake controller for the first time, the LED lights will signal your progress.
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.
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!
Then plug the custom-fit harness right into your vehicle and the brake controller and you're done!
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-control installation kit (ETBC7 - sold separately). A 30-amp circuit breaker kit (331-CBK30-EB - sold separately) may also be required for installation.
For assistance in properly wiring the Tow-Pro Liberty, please refer to the diagrams below:
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.

Hey, everybody. Ryan here at etrailer. Today, we're gonna be checking out the REDARC Tow-Pro Liberty trailer brake controller. If your trailer has brakes, you're gonna need a way to apply them. That way, you can slow everything down safely. And that's where a trailer brake controller like this REDARC here is gonna come into play.
What this is gonna do whenever you hit the brakes, it's going to apply the brakes on the trailer, bringing you to a complete stop. One of the things that really sets the REDARC apart from some of the other brake controllers is the size. You know, it looks a lot different. The only thing you're gonna be able to see is the adjustment knob here. And the rest of the main body of the brake controller, I guess you'd call it, sits up behind the dash.
So, you're not gonna have this big box that's always in the way and an eyesore bolted up to your dash. And with this one, I think it turned out really good. We actually had some factory switches and whatnot here already. We had a blank one, so we we're able to mount this up in there. And so, it looks almost factory and a really clean appearance, and still really easy to get to.
One of the things with a brake controller like this as well is the fact that it's what's called proportional. So, what that means, more or less, however hard you apply the brakes, the trailer brakes are gonna match that. So, it just makes it a lot smoother and a lot better braking experience. So, to kind of give you an example of that, let's say, if you're going down the road and approaching a stop sign, and you're halfway on the brake, trailer brakes are going to do the same thing. On the other hand, let's say, if you're going down the highway, maybe an accident up ahead or something along those lines and you gotta really stand on the brake to slow things down, trailer's gonna do the same thing.
So, you're not gonna feel the trailer dragging or wanting to push you around. You're actually gonna be stopping as one hole unit. This particular brake controller is gonna be good for trailers that have either one or two axles. And there are some adjustments so you can change your brake force. So, you have the knob here. That's 10. That's zero. So at zero, you'd have no braking force. And so, you can kind of fine tune it. So, let's say, a good place to start is probably five or below. Let's say maybe you got a light trailer and nothing in it, you're gonna pick something up, you might only need a one or two, something like that. But then you load it up and realize it's not braking quite as hard as you'd like it to, you can always dial that up a couple clicks. So, you can really fine tune it for your particular load and what you're gonna be doing, and your particular driving style. It's also gonna have a manual override button and all you do is you just push down on this. And so, I'm actually hooked up to a test box, which simulates a trailer. That's why we're getting these lights going and everything. But you can see when you push down on this, that light's gonna glow red and that means you're gonna be just applying the trailer brakes. So, let's say, if the trailer starts to get swirly, kind of gets away from you a little bit, you can hit that, slow the trailer down, straighten it back out, and continue on. As far as installation goes, ours was not bad at all and I think that'll be the case for most people as long as your truck has a factory tow package. Essentially, all you gotta do is find the connector, plug it in, mount up the the box, and then mount up your knobs. So, it's more tedious than anything, but as long as you take your time, you should be in good shape. I do wanna mention, for those of you, if your truck does not have that factory tow package, so if you don't have the factory seven-way connector back there, you are gonna have to get a couple of other things, which is just probably gonna be rare for most of these vehicles. But we'll need a four-way flat trailer connector, etrailer.com universal brake controller install kit, and the REDARC universal adapter plug to make everything work. But like I said, chances are really good this info will get you going in the right directions. And that'll finish up our look at of the REDARC Tow-Pro Liberty trailer brake controller..
delivered as promised, installed the brake controller and now ready to get my trailer on the road. Thank you.
