Relay Board - 3106996.022 by Dometic Dealer Direct
Description
Heat and Cool Relay Analog Control Board Kit Camper Trailer RV3. Towbar Electrics 7 Way Bypass Relay for Canbus Multiplex Wiring Smart TR186
Description
This latest smart relay is designed to work on all cars with a negative earth system.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 (now tested in MOT's).
Wiring Guide
The wires from the relay should be connected;
Yellow Wire to Left hand Vehicle Indicator.
Blue Wire to Vehicle Fog Light.
White Wire to Vehicle Earth/Chassis.
Green Wire to Right hand Vehicle Indicator.
Brown Wire to Right hand Vehicle Side /Tail light.
Red Wire to Vehicle Brake Lights.
Black Wire to Left hand Vehicle Side / Tail light.
Grey Wire to Vehicle Reverse Light.

Relay Terminal 1 To Trailer Left Hand Indicator. (Pin 1 in tow ball socket)
Relay Terminal 2 To Trailer Fog Light. (Pin 2 in tow ball socket)
Relay Terminal 4 To Trailer Right Hand Indicator. (Pin 4 in tow ball socket)
