So I need to know which wire on the back of the gauges is for the tach signal. In digging around in google I have found that it should be either black, green, gray, or white with a blue stripe. None of those wires exist on the gauge wires except for the green which leads to a bulb. I know the black wire is on the tach, but I've already rewired my whole engine to get the Autronic SM4 computer set up, so no more stock igniter. Anyone have any ideas?

There should be only one going to the tach. If you have a voltmeter, check for continuity between the tach gray wire and the gray wire at the igniter module. That's your tach signal. Good luck!

That wire diagram is exactly what i've been looking for!!! It says the tach wire from the coil is A10! A10 is IG- on the back of the gauges. IG- is the signal! yay!!! -------------------- -Jay
