2 INSTALLATION 2.1 Mounting the main unit The Tow-Pro® Elite should be mounted inside the vehicle cabin using either M4 screws or other secure fitting methods at the mounting points provided. It is essential to mount the unit in a location which allows access to the intended remote head location. The Tow-Pro® Elite can be mounted in any orientation as long as the installation is secure and the main unit cannot move or change orientation once installed.
2 INSTALLATION 2.2 Wiring the brake controller A Fuse or Circuit Breaker of appropriate rating must be installed to protect the vehicle system. Please refer to the installation instructions on page 7 for specific instructions on where to install the Fuse or Circuit Breaker and for appropriate Fuse or Circuit Breaker rating. The Fuse or Circuit Breaker must be installed as close as possible to the battery.

The Input Power (Black) wire must be connected directly to the positive terminal of the start battery via a Fuse or Circuit Breaker and not through an Ignition source.
2 INSTALLATION 2.3 Mounting the Remote Head The Tow-Pro® Elite remote head is designed to be mounted at a distance from the main unit, allowing for a neat, convenient installation and not impeding on lower leg airbags or driver leg room. The Tow-Pro® Elite remote head is designed to be mounted on or around the vehicle dashboard and when installed correctly, complies with Australian Design Rule (ADR) 21, which sets requirements for devices mounted on the dashboard.
2 INSTALLATION 2.4 Active Calibration When the unit is first powered, Active Calibration must first become confident in the vehicle direction of travel. Until this time the LED will flash Blue/Green. Time Time During Calibration: Once Calibrated: Active Calibration constantly monitors the vehicle’s direction of travel and allows the Tow-Pro® Elite to ‘learn’ and continuously confirm its mounting orientation.
2 INSTALLATION 2.5 Installation Accessories REDARC offer a range of vehicle specific switch inserts and vehicle specific wiring kits designed to make the installation of the Tow-Pro Elite easier. The range includes most popular SUV & LCV’s and is frequently being updated and added to. A full listing of Switch Inserts and Wiring Kits is available on and can be purchased from the REDARC website.

3 OPERATION 3.1 Adjusting the Braking Force In both modes the braking level can be adjusted to suit varying trailer loads, braking requirements or user comfort by adjusting the control knob on the remote head. The lower end of the scale (below level 5) should be used as a starting point and adjusted accordingly once braking requirements are established. If a lighter braking level is required, turn the control knob to a lower number (anti-clockwise) to reduce the trailer braking force.
3 OPERATION 3.3 Operating Modes The Tow-Pro® Elite offers two modes of operation - Proportional and User Controlled. On the first application of power to the black wire, the Tow-Pro® Elite will start-up in Proportional mode. Every time a trailer is connected, the Tow-Pro® Elite will start up in the mode that was last selected (provided the black wire has remained connected to power/ battery positive). 8 2 3.3.
3 OPERATION 3.3.3 Changing Modes Changing modes can only be completed with a trailer connected. Ensure the vehicle has come to a complete stop before beginning the mode change process.
3 OPERATION 3.5 Electric / Hydraulic Brakes The Tow-Pro® Elite is designed to operate both electric and electric / hydraulic braking systems in both Proportional and User Controlled Modes. The unit requires no user input to select the electric/hydraulic mode. Most Electric / Hydraulic braking systems will require a separate 12V power feed for the hydraulic pump.

3 OPERATION 3.8 LED Indication The Tow-Pro® Elite will indicate both Mode and Fault Condition through colour and flash sequences of the LED indicator. The table below shows how the Tow-Pro® Elite will indicate Normal Operation of the unit. NOTE: LEDs will glow full brightness when gain control is adjusted or manual override is pressed. After release of the gain control knob the LED brightness will reduce. This is designed to be less intrusive on driver’s vision at night.

4 PERIODIC MAINTENANCE/CHECKS Ensure that your trailer brakes are installed and are operating correctly: Improperly installed and/or faulty trailer brakes can cause erratic vehicle or trailer behaviour with the potential to cause a road accident. For this reason, it is of utmost importance that your trailer braking system be installed/maintained by a qualified installer. Always check brakes at low speed each time a trailer is attached to your vehicle.
5 FREQUENTLY ASKED QUESTIONS The LED is flashing Blue/Green, what does this mean? A Blue/Green flash sequence indicates that the unit is in the process of calibration, as the unit becomes more confident in it’s calibration the Blue will appear for longer. Keep driving and eventually this will turn to a solid Blue. Is the Tow-Pro® Elite approved to use with the my Electronic Trailer Stability Control system? The Tow-Pro® Elite is approved for use with the AL-KO ESC and the Dexter Sway Control systems.
