Towbar Towing Electrics 7 Way Bypass Relay for Canbus Multiplex Wiring DEVICE
Description
STOCK IN AUCKLAND
This latest smart relay is designed to work on all cars
Easy to wire if you can wire a tow bar to the back of the lights like on older vehicles, with this relay you can wire up even the most advanced modern car.
Totally protects the cars wiring and control module from faults in the trailer, short circuits in the trailer, extra load etc.
The wires from the relay are connected directly to the back of the vehicle lights as with normal tow bar wiring to provide a signal to the relay. The relay then provides outputs to the trailer/caravan lights powered directly from the battery.
Because the lights are powered from the battery, this latest relay draws only 0.001A (1ma) from the vehicles lighting system, which will not effect any bulb warning system or vehicle wiring on even the very latest vehicles.
Will suit vehicles where the sidelights are powered from the same wire as the brake lights or fog lights (see wiring guide below).
Provides audible warning buzzer for trailer light operation
If you vehicle side lights are powered from the same wire as the brake lights, just connect the red wire and leave the brown and black wires disconnected (insulate bare ends). The smart relay will sense the input and output correctly. The red wire only needs to be connected on one side of the car.
If you vehicle side lights are powered from the same wire as the fog lights, just connect the blue wire and leave the brown and black wires disconnected (insulate bare ends). The smart relay will sense the input and output correctly. The red wire only needs to be connected on one side of the car.
The 12v supply should be fused at 15A and should be routed so the cable cannot snag or break.
The relay should not be mounted outside or under the vehicle
