Tech Answer

Where do I connect the green wire on my tachometer?

The green wire from the tach reads the electrical pulses from the ignition. For most standard ignitions it connects to the distributor primary or negative (-) side of the ignition coil. However, do not connect it to the coil of an MSD ignition. Some electronic ignitions have a tach terminal on the box itself. If you have such an ignition, this is where the green wire goes.
