Dani - Without seeing the instruction set, it's a little difficult to say exactly what you're looking for, so I'll give you the basics. The door lock switches provide a negative (or ground) signal to the door lock module, which then provides a positive signal (+12V) to the solenoids in either the lock or unlock direction. If you tie into the DMC system "upstream" from the door lock module, you want the alarm system to provide a negative signal (ground) for lock/unlock functions. In your instance, I would guess green would go to the small brown/slate wire from the door lock module, the blue would go to the small brown/pink wire, and the gray would not be used. However, that is an educated guess, so use it accordingly. Since your are using negative signals, you shouldn't hurt anything if it's wrong in some way.
