I don't want to oversimplify, but can't you/someone just unplug the wire(s) that run from the wing to the control switch? Or would that still set off an "alarm" in the car? You're best bet may be to take it to a local alarm/audio company that is familiar with all things electrical...(but do your research on them first!)
Just a suggestion of course, I'm not sure if this has been considered since there's no mention of it.
