Well, the relay diagram isn't right. But mine is in the relay center he is thinking of. MY FSM calls relay 3 above the passenger'* foot as ELC for Buick and Olds and Fog lights for Pontiac. So I dug into that one. I've got voltage at pin 1 to ground, but not pin 5 to ground. Pin 1 and 5 both go to fuse 12 above the driver'* foot and split somewhere between that fuse panel and the relay center. I've got continuity from the fuse to pin 1, and not from the fuse to 5. So I guess I need to find the break in the wire somewhere under the dash.
So I know this relay 3 that is supposed to be for the fog lights is wired to the ELC fuse. Does that make my car a LeSabre SSE or a 88 SSE?
