Installation Manual

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-The unit.
When the units are paired and the ignition is on in the tow vehicle then the ignition
output on the Anti-The 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-The 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.
The WiTi Wireless Towing Interface is supplied with a separate WiTi
Communication Module that must be connected to an existing Anti-The Unit in
the caravan or trailer.
Locate the Communication Module next to the Anti-The Unit and connect with
the supplied RJ45 cable. There is a corresponding connector at the bottom of the
WiTi Anti-The Unit and the side of the Communication Module.
The Communication Module is used to wirelessly transfer the lighting and braking
signals from the Wireless Towing Interface to the Anti-The Unit and then on to
the lights and brakes of the caravan or trailer.
