Re: Locking system! (Advice) (archive)

The control unit has the relays in it.
Check for these inputs /signals to the control unit itself.
Pin #3 Red/white wire, hot all the time from Fuse #27 in the fusebox.
Pin #4 Ground wire,: Brown
Pin#5 Green wire: ignition switch power only, used to feed the impact switch inside the control unit in the event of a crash[opens the locks automatically as a default for safety crews and passengers]

Signal wires: "Lock" request wire Pin #7 Yellow/Blue wire, runs from the L/F and R/F lock motors
Internal jumper on same line to Pin#8, which is a Green/Black wire to the Trunk Lock motor

"Unlock" request wire Pin#6,Green/Blue wire; Runs to both front door lock motors
Internal jumper[inside control unit] on same line to Pin#9, Yellow/Black wire to the Trunk Lock Motor

Unlock Inhibit Wire, Violet wire, ETM doesn't show which pin, but you're out of wires so it shouldn't be too hard.[possibly Pin #10

Pin#1 "Lock" function wire to the rear doors and the gas flap motor, these are only slave motors, they can't send any requests [Blue Wire]
Pin#2 "Unlock" function wire to the rear doors and the gas flap motor [White Wire]

Pin#11 Black wire, Power to the R/F, L/R, R/R, and Trunk lock motors to enable the switching of the motor

There is a micro-switch mounted on the L/F lock cylinder on a bracket for inhibiting unlocking[known as "double-locking]The Violet wire from the control unit changes to a Brown/Blue wire before reaching this micro-switch, the other wire going to it is a White/Black wire

Should also be a microswitch at the R/F for locking[really a lock request switch, as the door lock motor isn't wired like the L/F one]

Hope this helps
