suitable to the 13-pin plug of the trailer control of reverse light 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 (digital method) acoustic signalling of switching-on fog light on the trailer  sequential on/off fog lamp acoustic signalling of recognition the connection and disconnection of trailer detecting and acoustic signalling of damaged directions lights on the trailer socket for connection of tri-colour LED indicator output for enabling of switching off PDC signalization in car OPTION: additionally variants of stitching off PDC signalling using separatelly PDC-OFF modules include separately circuit for trailer battery charging supply voltage (+12V) is permanently brought out in the socket

Module with standard functionality (WH2S) with 13-pin's socket (G13). Kit contains all accessories for connection of module to the car's electric system - and socket G13. Like whole series - this module have integrated all-in-one socket which makes an installation easier.


Module have standard functionality, this mean that above basics functions it make possible eg.:

  • switching-off the control unit of parking sensors (PDC);
  • switching-off the fog light (54G) on car when is there are still switch-on on trailer;
  • signalling of damaged the directions lights on the trailer by buzzer's acoustic signal.


To the module can be connected (optionally) RJ11-LED-5 - tri-colour LED indicator which inform about:

  • connecting of the trailer;
  • damaging the directions lights on the trailer;
  • switching-on fog light on the trailer;
  • loading of trailer battery (when is used: ICM).


This set can be supplemented with ICM module (intelligent charging module) which is recommended eg. for caravans. ICM module protects car battery because allow to load caravan battery only when car egine is working.


NOTE: If ICM module will not be used then circuit of load caravans battery should be equipped with necessary elements - by own. Sample diagram of these (optional) connections is in basic documentation.
