Door Lock Solenoid Wiring Diagram?

[ClayW]

Can anyone tell me the function of each of the wires from the door lock solenoids? I see five wires coming out:

UPDATED:

Black
Brown - Ground (-)
White -
Blue -
Green/Blue -

Looks like the blue and white are lock or unlock, depending on the polarity. The black, green/blue, brown and white seem to be for connectivity and signal for the central locking computer and relay bank.

e30 wiki has good wiring diagrams too. i know brown is ground. the green/blue is probably the power source but don't quote me on that
