Digital module with standard functionality (WH3Q-S) with 8 wires in 13-pin's socket. Kit contains all accessories for connection of module to the car's electric system.

This set is dedicated for Toyota RAV4 (gen.5 2019>), Highlander (gen.4 2020>) and Suzuki Across (2020>). Kit use factory socket in car for connection cable harness. For this reson installation pedriod is simpler and faster.


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

  • possibility of switch-off the control unit of parking sensors (PDC);
  • sequence switching-off the fog light (54G) on car when it (54G) is 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) LED-RGY-500 - 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 (required G13-ICM-Kit).


This set can be adopted to using with eg. caravans, where is required additionally connections. In this case should be used G13-ICM-Kit, which "activate" rest of pins in socket. Moreover - this kit include ICM module (intelligent charging module) which is recommended eg. for caravans. This module protects car battery because allow to load caravan battery only when car egine is working.
