I just did the Z28 cluster install on my '96 and I'm having tachometer malfunction. I ran the wire to red 13 on the pcm and made sure it snapped in. It seems to me that the tach is not receiving the signal from the pcm. Can somebody give me an idea where to start? Is there a way to check to see if the pcm in fact is sending power to the tach or I might have a break down in the wire? Is there any other way to hook the tach up? If our cars had the standard HEI distributor,it would be a done deal,but with the optispark,I'm lost. I don't think having my pcm tuned by Brian at pcmforless would cause my tach not to work.
Help me out here guys,
