sorry, i thought I updated this - my gauges are all working. and actually, that thread you posted was partially what helped me out. the rest of the mess was that the previous owner unhooked the coolant temp sensor and the oil pressure sensor.
The only issue im having currently, is that the dimmer does not function correctly, and I've taken it apart and its all clean. It either turns the lights on (full power) or off. Its not a terrible problem - and if I ever upgrade to LED's, its perfect i guess. :-)
