If anybody could help me, it would be great. I took my '92 5.0 in to get the ac fixed. The mechanic had my car for 3 days and still didn't fix my ac. He said he could not locate the AC Relay. I think it is the same as the wide open throttle relay. Anybody know exactly where it would be located?
Also he screwed up my rpm gauge. I know its some kind of electrical problem and it always reads at about 4,200 rpm. Any clue on how to fix that?

also depending upon how late a 92 you have, there could be a FP relay near the WOT relay - just so you know. IIRC, the relays are the same part number.

the tach uses the neg coil signal.

good luck.
