Ah got you. As the switch has two switches, left and right (for opening and closing), I'd need two relays.
I may actually go ahead and do this. I'll wire it up to two lights to make sure the circuit works first
I'm going to do the same thing with the spoiler too, and re-wire the wires from the footwell to the dashboard to put the 996 spoiler button into place. Then wire a 4-second timer relay into the switch to operate the spoiler.
