Central locking

[Amuso]

I assume the white "thin" cable that goes into the round 3-pin connector and continues as three separate wires is from the key lock itself, and is the one that supplies the vacuum unit with either +B or GND for lock/unlock?

What is the other for? That goes into the door locking mechanism itself. Is it a switch that tells the alarm wheter the door is locked or not? (my car has the factory alarm option).

On the vacuum actuator is an electrical contact.

When you manually lock and unlock the doors (using your key)
this contact 'tells' the vacuum pump to open or close all doors.

At least, that's how it works on my car.
