SPRINTER Engine System CR4 T1N - OM646 Wiring Diagrams. Hello to everyone I'm looking for central locking diagramm of 2006 c class w203. I saw this diagramm in your forum, but it was unreadable. It would be great if somebody can repost it. Thanks. RGDS YnibaudeauW203 diagram - Central locking - (courtesy Haynes manual)
I have a central locking switch in my 2006 Sprinter 2500 dash which was disconnected without noting where the blue, green and black wires connect to the switch. Does anyone know where the blue green & black wire connect on the central door lock switch?. I included the wiring diagram attached. 1) When the signal is sent to lock or unlock the doors, is +12v or ground sent to the solenoids? Or does it flip flop on the blk/red and blk/blue wires depending on lock/unlock? 2) What kind of signal does the central timer module look for from the door sensors in the solenoid? Is it ground? +12v?
