I have a ground already on the chassis near the fuse panel inside the drivers door.What I need to know is which one of the 5 thin wires in my left pillar is hot ONLY when the ignition is on and NOT all the time. I have accessed the wires but have not tested them yet. Trying to avoid poking into any of them until I am sure which on is ignition activated.

This was another post I found but for an 05 roadster. I don't know if the wires are the same:
