WiTi Wireless Trailer Plug Connection with built-in Anti-theft & GPS tracking (Optional)
VEHICLE PREPARATION REQUIRED
IMPORTANT:
To use the WiTi system, the tow vehicle MUST be equipped with a 12 Pin Trailer Socket. The wiring
of the 12 pin socket on the tow vehicle must follow Australian wiring guidelines as shown below.
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 DCDC charger, AES fridge or anti sway 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.
