Right my pair of self lock programmable timer relays will arrive tomorrow and I have tracked down a copy of the BCM pin out so I'm all set as to what wires I need to tap into to trigger it up and down.

The advise I'm after if anyone has any ideas is I want to use the unlock/lock of the car to trigger the spoiler up and down but today I was power probing the central locking pump in the boot thinking I would find either a trigger + (12V) or - (earth) as I can work with either and I couldn't find anything of any use there, so if anyone has any ideas where I can take the triggers from I'm all ears.

Failing that I'm going to have to go the easy route which is to use the ignition as a trigger so it will deploy on start up and retract on shut down which is ok but I really wanted to use the central locking as I think it would look more trick on the blip of the remote.
