if you are looking at the BACK of the instrument cluster, you will see two wiring harnesses. a black one on the left (passenger side) and a white one on the right (driver's side). the white harness has all of the signals fr the tach and for most of the lights on the inst cluster. the signal or the tach should be Pin #8. which is the 8th pin up from the bottom of the harness. you can get power and ground from either the black or the white harnesses by tracing where the power and ground wires are for each guage pod.
hope this helps.
