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.
If you go the +12 trigger on startup, there is a hot right at the panel where the switches (spoiler switch) are. Does the spoiler control (switch) a +12 or is it a signal to/from the BCM? If +12, you can use that 12 supplying the cigg lighter to a relay, as it powers on when car starts. you can then use the spoiler switch to 'override' that sequence/relay if the need arises (ultra minimum of parts/wiring if done right).
