The WH0-SERVICE module is a simple trailer lighting controller designed for service replacement in an existing installation of any faulty universal controller. For this purpose, all connections to the module are made using screw terminals (power supply, input signals from the car lights, output signals to the trailer socket).

The module supports trailer lighting (only lighting) and operates 1:1 - i.e. an input signal causes an output signal. The module has in-out for signals for all lamps in the installation with a 7-pin and 13-pin socket (8 ‘active’ pins).

It should be noted that this module properly operates both incandescent and LED car lighting and works correctly with ‘PWM’ lighting control in the car (i.e. when one wire is used to signal two lights, e.g. “stop” [54] and ‘normal’ [58L/R]).

The module doesn't support any ‘additional’ functions, such as disabling parking sensors nor controlling the power supply to a caravan battery.

NOTE: When installing the module, it is essential to comply with the requirements regarding cable cross-sections and power supply protection!
