My 1971 Mach 1 had dash light problems. In removing the dash to replace and check on things I found that the circuit board was modified from a non tach board to a tach board and they used jumper wires to connect the dash lights. I assume just getting a new tach circuit board would do the trick but the resistor seems to be right in the middle of of where the tach sits. What am I missing here?
