Complications can arise using this scheme. Non-contact tachometers often use a laser or optical disc to measure and are ideal for mobile applications. I have tried runing a JUMPER wire direct from the CDI to the tach - with no results. Be warned, however, that rolling back the mileage to make your vehicle appear to have less wear and tear than it actually has can get you into hot water if you later sell the vehicle and are caught trying to cheat someone. i think that another brand engine (unknown kind) came on boat so the tach. Pontiac used two different physical sizes of hood tachs on GTO's.
