suitable to the 7-pin plug of the trailer working with LED and bulb lamps and PWM steering working with LED and bulb lamps on the trailer recognition of PWM steering of car lamps (analogue method) directly steering of fog-light of trailer

Module with basic functionality (WH3L) with 7-pin's socket (G7). 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.



NOTE: Please remember, that G7 not include circuit for REV light. For example in Poland it can be used only with "lightweight trailer" (gross trailer mass up to 750kg).
