What is the 3 pin connector for? Only some models have it.

 

Door lock **** switch.

 

Cant be, the lock **** switch still operates both doors fine

 

The driver's door lock **** switch is not the same thing as the driver's door switch.

The driver's door lock **** switch is controlled by the key.

 

Ah, you mean the fob? Its still not that because remote lock/unlock still works. Or am I misunderstanding, not exactly sure what you mean by the drivers door lock **** switch.
If you mean locking/unlocking via door lock with a physical key, that still operates both fine.

 

It is a switch that is part of the driver's door actuator, that uses the key to lock and unlock. See circuit diagram, etc.

 

Sorry I think I posted under the wrong forum thread, I have an ep3. Its also on the passenger side. I dont understand what does the door lock **** switch do.

 

It is a similar circuit on an ep3. The driver door lock **** switch is used when the door is closed, and you use the key to lock or unlock all the doors. Turning the key send a ground signal to the multiplex control unit in the under-dash fuse/relay box, where the multiplex controls locking and unlocking of all the car doors.

If it is on the passenger side, it doesn't have any functionality.

 

Oh, now I understand, thank you for explaining. I wonder why the previous one on the passenger side had the 3 pin connector slot and the actual connector which I just left unplugged. Can it be the wiring system just has them on both sides for the right hand drive versions? Or is the wiring swapped from another car at some point in its life..
