Off-Road Mode

Redarc Tow Pro Elite User Controlled LED Signal

The off-road mode is a unique feature of the Redarc Tow-Pro Elite. In this mode, the brake controller will apply your trailer's brakes with a preset amount of power, independent of what your tow vehicle is doing. This is ideal for off-roading or challenging conditions. Set the power low if you're towing through sand or mud so that the trailer doesn't stop with too much force and act as an anchor. If navigating a steep descent, set the power to a higher level to ensure that the trailer doesn't push against the tow vehicle.


To activate the off-road mode, rotate the knob counterclockwise to 0 and apply your vehicle's brakes. Push down on the knob twice (2 times within 1 second) and release the brakes. The knob will turn green to let you know that the mode has been activated.

How to Use Redarc Tow-Pro Elite

Adjusting the braking settings on the Tow-Pro Elite 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 Elite 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 Elite

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.


Redarc Tow Pro Elite Brake Controller Calibration

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 Elite

The Elite 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.


Redarc Tow Pro Elite Dash Mounted Remote Knob

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 Elite 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 Elite. Do not attach the module 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 will either plug directly into the controller or will splice into the included wiring harness - no need to hardwire to your vehicle.


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-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 Elite, please refer to the diagrams below:

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 Elite 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.

I have been pleased with the Redarc controller. I like that it's hidden away from sight except for the knob. It works as advertised with no issues whatsoever. I tow a dump trailer rated for 16,000 lbs with an 06 ram diesel and the brake controller makes it so much easier on the vehicle brakes. I highly recommend.

  • - SEE SOLUTION UPDATE WITH PART # C32FV IN COMMENT SECTION BELOW - I have a brake controller recommendation but at this time it doesn't look like we (or our manufacturers) have any information or at least an adapter harness to fit with the wiring you have under the dashboard on your 2023 Mazda CX-50.

  • Wiring Location For Trailer Brake Controller On a 2021 Buick Enclave With Factory Trailer Package
  • Your 2021 Buick Enclave has a wiring pigtail and not a connector for wiring a Redarc Tow-Pro Elite Trailer Brake Controller # RED44FR. The 4 wires are located below the OBD2 port behind the side kick plate(see Image). This is where you will be able to attach the included pigtail using the Heat Shrink Butt Connectors # DW05744-5 and # DW05745-5. You will only need 2 of each connectors for the 4 wires that connect to the brake controller pigtail.

  • Troubleshooting Redarc Tow Pro Elite That No Lights Come On
  • Since the Redarc Tow-Pro Elite Trailer Brake Controller - 1 to 3 Axles - Proportional # RED44FR you have does not have any lights you are correct that it is not recognizing that a trailer is connected. What you will need to do is inspect the 7-way connector on your tow vehicle and trailer looking for any corrosion or debris in the connectors that can cause a connection issue. If the connectors look good double check the wiring on the vehicle and trailer side to verify that no wires

  • Brake Controller Installation in 2019 Ford Ranger
  • We have not yet (as of April 2019) had a chance to install any wired trailer brake controllers on a 2019 Ford Ranger so for guidance I checked with my most trusted brake controller expert at Tekonsha. Based on what I could learn about the truck if the Ranger has a factory-installed 7-way it should have a standard brake controller connection port above and to the left of your left knee when seated; this will be near the kick panel.

  • Does Redarc Tow-Pro Elite Trailer Brake Controller Have to Draw Power from Battery
  • When powering a brake controller like the Redarc Tow-Pro Elite Trailer Brake Controller # RED44FR you have to power it directly from the vehicle battery. Mainly because it would prevent the controller from shorting out any of your vehicle's power circuit in the event of a short, but also because none of the aux power sources are going to be rated high enough for the amperage load of a brake controller. I attached a help article on installing brake controllers plus a diagram for you to

  • Blue Light On Redarc Tow-Pro Elite Trailer Brake Controller Stays On with Vehicle Off
  • The controller will actually wake up from sleep mode when the door is opened so that's likely why you still see the blue light on even with the vehicle off and trailer unconnected. This is common for all brake controllers including the Redarc Tow-Pro Elite Trailer Brake Controller part # RED44FR. If you peek through the window, you should see the light on the controller go off after about 15 minutes of inactivity.

  • Service Trailer Brake System Error Message on 2015 GMC Sierra
  • According to the owner's manual for a 2015 GMC Sierra, the "Service Trailer Brake System" error message can appear on models equipped with the factory integrated trailer brake controller (ITBC) and represents a problem in the trailer brake module or wiring that will not allow power to be sent to the trailer's brakes. It is okay to drive the vehicle with this error message present but you will not want to do any towing until it is fixed. Unfortunately, third party support for the factory

  • How Would Redarc Tow Pro Elite Install in 2019 Toyota Land Cruiser
  • To install the Tow Pro Elite brake controller part # RED44FR in your 2019 Toyota Land Cruiser you will need to start with a 4-way (if you do not have one). For that you would want the # C59496. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product as well.
