Oooh, just found JPG of wiring diagram on my office machine (sure hope my GM never walks in on me when I'm doing this). Not much help -- ignition module ground is black, duh -- but may come in handy in future... Module is behind driver's seat, under evil demon infested bowels from the depths idle speed ECU (sorry, couldn't resist). Find black wire there and run a temporary one to something like seat belt bolt (my personal favorite known good ground). Don't know if you can use metal cage itself. Seem to remember cage on relay side isn't grounded.
