W201 190E Central Lock wiring color code help
 

I have a Hella Vacuum Supply Pump for W201 central locking system where the circular socket just crumbled away due to age when I removed it and it bares three wires blue, green and yellow. My problem now is how to put it back to the right poles without blowing or burning something. Below are the poles where I need to know which wire goes to which pole. Thanks!
