Kuhlka - looks like the oil pressure indicator is a black wire running to the cluster. Pin 6 in the instrument wiring cluster. Looks like the ground runs right off the oil pressure switch, so the black off the other side should be the power right? Or is it a ground wire all the way through and the light is illuminated by the oil pressure switch closing the circuit and allowing the ground wire to work?

Those look slick! Might have to pick some up for all those little wiring projects.
