I need help with wiring up a new tach. I'm running a 350 small block in a 1965 Chevelle with a Mallory Comp 9000 Unilite distributor and a Mallory Pro Master Coil. I am trying to wire a Chevrolet tach, Model 10185001 and the instruction sheet states that the warranty will be void if the tach is wired to the coil on an MSD ignition. It advises to wire the tach to the tach terminal, but I can't seem to find a tach terminal. Any suggestions would be appreciated.
