Where do I post this question and can anyone answer it? I just need to know what wires I need to tap into on the pcm to make the Tach get a signal. Wire color and pin number would help out alot. This is for a 99 Z28 ls1. This is a monster tach made by autometer and does not have the memory feature, just the basic 10,000 rpm tach..
Thx. Jeff
