Alarm

[Per Lindgren]

You can just pick a feed from the door switch. The thing is that there
are switched earth wires from the door lock to the central locking unit,
and the witch is in the door handle. Lock, and one wire gets signal.
Unlock, the other wire gets signal. cant remember the colors right now,
they are brown with some stripe. See in the Bentley, most Audis use same
color wires.
