Module with basic functionality (WH3L) with 8 wires in 13-pin's socket (G13-8). Kit contains all accessories for connection of module to the car's electric system - and socket G13-8 already is connected with main harness whitch makes an installation shorter.


Module "copy" signals of lights from car to socket of the trailer.


This set can be adopted to using with eg. caravans, where is required additionally connections. In this case should be used PowerKit, which "activate" rest of pins in socket. Remember, that circuit of load caravan's battery should be equipped with necessary elements - by own. Sample diagram of these (optional) connections is similar to basic documentation of WH3L-G13.
