I have a 1992 5.0 Mustang GT, and I Just replaced the gauges with some new white ones. (the face plates). I got it back together fine. but im having problems with the instrument panel. I was careful with all the needles putting them in the same positions they were in when i took them off but now my Battery Voltage, Oil pressure and temperature gauge don't move, they stay at the bottom. my tach works but my speedometer reads 5 miles over what its actually going. not sure on my gas gauges yet. looks fine really hasn't moved. also when i turn my lights on it barely illuminates my dash maybe 20%. I scraped off all the extra goo when i was taking off the old gauges so i don't understand that part. anyways I'm not sure what to do or how to fix it. just got them in today.
