Speaking of this, i put in a 71 mach 1 guage cluster( tach side only) to my 71 fastback, the tach worked at one timr when i had regular points, now i went to a pertronix and cant get it to work, any ideas fella's? Can someone tell me how the wires work? one to a 12v and one to the + side of coilis what ive read many times but it doesnt work. If i hooked it up backwords will that fry the tach? -Jon

Hooking up the tach backwards can hurt the motor. The likely cause is the signal isn't strong enough or you didn't use the right wire on the coil.
