Wireless Towing Interface
Operation & Installation Guide

Australia’s Most Advanced Anti-Theft System for Caravans and Trailers

Warnings & Safety Instructions

Do not operate Wit unless you have read and understood this manual and WiTi is installed as per the instructions.

Wit Wireless Towing Interface requires Wit Anti-Theft to be installed in the caravan or trailer
Wit automatically pairs when in range but it is always good practice to check the lights before towing to ensure they are all operating.

Witi Wireless Towing Interface

Wit replaces the cables connecting a tow vehicle and trailer or caravan with an advanced Wireless Towing Interface. WiTi transmits all lighting and braking signals from the tow vehicle to the caravan or trailer wirelessly. WiTi complies with Australian Design Rules when installed as directed.
WiTi Wireless Towing Interface supports Can Bus vehicles and vehicles with advanced electronics. Wit supports vehicle specific towing modes and features for example, disabling reverse sensors when hitched. These features will be enabled when the WiTi Wireless Towing Interface is in range and paired with the WiTi Anti Theft unit in the caravan or trailer. Please refer to your vehicle hand book for vehicle specific towing modes.
WiTi supports all third party electric brake controllers as well as the WiTi Wireless Electric Brake Controller (sold separately).
Note: Transmission of lighting signals is disabled when the alarm is activated on the trailer.

witi Wireless Towing Interface - Pin

Pin 8 must be connected to a permanent power supply from the battery in the tow vehicle. It does not have to be a high current supply as the WiTi Wireless Interface will draw very little current.
Pin 9 is optional and can be connected to an ignition source in the tow vehicle.
This circuit works in conjunction with the ignition output on the Anti-Theft unit.
When the units are paired and the ignition is on in the tow vehicle then the ignition output on the Anti-Theft Unit will provide 12V. The best way to describe this is as a wireless relay. This connection can be used for any device on the caravan that requires an ignition trigger for example, a DCDC charger device in the caravan.
This circuit is optional and does not have to be connected if you are not using the ignition output on the Anti-Theft Unit.
NB. Not all vehicles are wired to Australian Standard VSB1 section 14 please test Pin 8 is 12V+ and Pin 9 is Ignition 12V+ before installing WiTi.
To operate simply plug the WiTi Wireless Towing Interface into the 12 pin socket on the tow vehicle.

WiTi Wireless Towing Interface and Communication Module Indicator Lights
There are two LEDs embedded in the WiTi Logo on the Wireless Towing Interface.
When the unit is powered LED 1 (Amber) will illuminate. When the unit is paired and linked then LED 2 (Red) will illuminate.

Pairing a new WiTi Wireless Towing Interface and Communication Module
Ensure the WiTi Wireless Towing Interface is plugged in and powered on (LED 1 is lit) and in range of each other – within 10 meters.
On the WiTi Wireless Towing Interface unit press and hold the “PAIR” Button.
Whilst still depressing the “PAIR” button, press the RESET Button for half a second and then let go of the RESET button.

When the RESET button is released, you will notice LED2 flashing rapidly while LED 1 is still solid. Let go of the PAIR button. The WiTi Wireless Towing Interface is now in PAIRING mode. The unit will stay in pairing mode for five minutes while searching for the Anti-Theft System.
Repeat the Pairing Process on the Anti-theft in the Caravan or Trailer.
On successful pairing the WiTi LEDs will flash simultaneously for 5 seconds on both units to indicate that they have successfully paired with each other. Once the LED’s stop flashing both units will exit PAIRING Mode and return to normal operation. Both LED1 and LED2 will now be illuminated when they are in range and powered.
If either unit did not detect a PAIRING partner during the pairing sequence, then LED 1 and LED 2 will flash in an alternating sequence for 5 seconds (LED1-LED2- LED1- LED2) this indicates that pairing has failed and the unit will then return to normal operation mode with just LED 1 illuminated. Repeat the pairing process.

Operation Guide

WiTi Wireless Towing Interface replaces the traditional cables between a tow vehicle and caravan / trailer with an advanced wireless connection. WiTi transmits all lighting and braking signals using the latest WiFi technologies for fast, secure and stable communication. Although wireless, WiTi is not dependent upon the Internet and communication is point to point between the vehicle unit and trailer unit. The signal is also encrypted for security and other wireless devices will not interfere with the WiTi
Wireless Towing Interface (mobile phones, Bluetooth, wifi devices, etc.)
No more cables to damage or rip out, no more corroded terminals and no more loose connections.

Low Power Mode
WiTi Wireless Towing Interface will enter low power mode if there is inactivity for 24 hours. In this mode power draw is less than 2 milliAmps. WiTi will exit Low Power Mode when it detects an input from the driving light circuit.
