uh, what am I supposed to have here. The haynes manual only speaks of a oil pressure switch (which it doesn't even show).
Pelican has this, the one at the top of the page? Auto Atlanta has a fair amount of stuff (couldn't link to the search results), though I've heard not the greatest stuff about them. Anyway, I think the switches just turn the green light on and off and the more expensive ones send the actual pressure (assuming that I have a gauge to show it). Oh yeah, and what's the wire that is supposed to hook up to it? There isn't one there at all right now.
