I cannot figure out what fuse controls the oil pressure and temp gauges on my car 89 GT. For some reason they have no voltage going to them and I have been trying to trace out the wires to see where they go, but I haven't gone very far. I have looked at the fuses listed on the fuse cover and they all tested good (volt/ohm meter). Kinda sucks not being able to keep an eye on my motor.....
