Wireless Trailer Interface Installation
Installing WiTi is as easy as wiring a standard 7 pin connector and connecting up to 12V power.
The vehicle unit can be installed anywhere within the tow vehicle although the boot or rear of the vehicle makes most practical sense as it is closer to the existing trailer wiring loom.
The trailer unit can be installed in any convenient location in the trailer or caravan and must be wired permanently to the house battery. The battery must be connected to an acceptable charging circuit whilst travelling, either fixed solar panels or Anderson plug. The trailer unit should be installed vertically with the wires protruding from the bottom of the casing as WiTi uses gravity to initialise and manage the anti-theft system. If not installed vertically the anti-theft functionality could be compromised.
Anti Theft System Installation
When installing the Anti Theft system with no Wireless Interface then as little as four wires need to be connected. Firstly the main 12V+ and NEG wires to the battery in the caravan and then the blue wire to the electric brakes and the brown wire to the driving lights. The driving lights are used as this will also flash the front and side markers during activation and de-activation as well as if the alarm is triggered. The left and right indicators can also be connected and will flash with the driving lamps, this is optional.
The trailer unit should be installed vertically with the wires protruding from the bottom of the casing as WiTi uses gravity to initialise and manage the anti-theft system. If not installed vertically the anti-theft functionality may be compromised.
* Note : If you are unsure of how to install trailer harnesses or 12V devices then please consult your nearest caravan / trailer repair centre or auto electrician.
