1987 mercedes 300d door lock

Purchase a Vac/ Pressure pump on E-Bay, Bench tested It functioned. Installed under rear seat and it did not function. Tested brown wire at pump, it was grounded. tested red/white wire, no power. traced red white wire to control module at passenger feet, wire tested ok. QUESTION; is this wire live all time or only when key actuates door locks. My problem is no power in either case. Fuse in C location has power. Any wire schematics for this CM?
