Hi Guys,
I am looking for a Wiring diagram for VY berlina wagon so I can work out how to install an addon alarm with back up batt, shock sensor and such, that uses the original keys buttons and works with the factory locks, immoblizer, alarm setup

This is from a 2002 - 2003 VY commodore I do suggest testing your wires before you connect anything,
All of these wires are located at the BCM, The BCm is under the Drivers side dash near the fuse box.
Ignition * Orange wire from BCM, plug X3
Ground * Black/Green trace wire from BCM, plug X1
+12V * Orange/Purple trace wire from BCM, plug X1
Lock Trigger * Brown/White trace wire from BCM, plug X4
Unlock Trigger* Light Green & yellow, Brown & Orange From BCM, plug X4 (Diodes are required)
Bonnet * Yellow/Black trace wire from BCM, plug X3
Boot Release Sense *Red/Green trace wire from BCM,plug X4
Actuator Lock Power *Black/Yellow trace wire from BCM, plug X4
-Door* Grey White & White Wire fom BCM, plug X4 (Diodes Are Required)
Actuator Unlock Power *Blue/Black trace wire from BCM, plug X4
Indicator * Blue wire from BCM, plug X1
Indicator * Lite Blue wire from BCM, plug X1
Hope this helps you out... Upgrades and be wuite dificult. But hope all goes well for ya
