bought a 94 GT 5.0. Had the AC charged. Fixed a leaking low pressure switch and it was supposed to work with a charge. It did not, I can jumper the switch and the compressor does not kick on. I'm getting no power to the AC compressor. I check both wires from the clutch to the what I think is the CCRM. It's like a 30 pin module right in front of the radiator. Unhooked it and homed out the power and ground wire from that connector to the compressor. Both wires are good. Since reconnecting the module. My volts,rpm and speedo gauges are not working. The temp gauge, fuel gauge and oil pressure gauges are fine. I'm at a loss as to what may have happened. And frankly I'm quite irritated. I found that the ignition module is now re-located to the inner fender well , I did move that around possibly messing with the ground on it. I dunno if that could have caused anything. Maybe I need to reposition it and ground it properly. Any ideas?
