Ok guys, just yanked my instrument cluster out of my truck because I'm sick of the tachometer reading being off. I've got it in complete pieces right now and I'm looking at the small circuit board that connects to the camaro tach. First I'll let you know the date on the tach is September 17, 1976. Secondly the highest rpm this guage can possibly display is 7000 RPMS. Back to what the tach is doing. When I'm idling and the tach is hooked up, it's reading twice as much as my actual RPM's. Like this tach is setup for a 4 cyl. Did they ever make a 4 cyl even in a camaro? Anyways, here's the attached image of how it's wired up now. Can anyone tell me how a camaro tach is supposed to be jumped so i can use it for a 8 cyl? Thanks!
