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!

Good luck! it would be easy if I still had the black wire from the igniter. I pulled out all of the wires coming from the sensors to run the new harness for the Autronic. So everything is out. It's not as bad as it sounds, everything is wired in except the dumb tach wire. I couldn't think because I had old 5s wires everywhere, autronic wires everywhere, and new power wires for other things, so I had to rip everything out for clarity. There are old videos of the birds nest on youtube. I'll be making another youtube video probably at the end of the week if you want to see how it's coming along. -------------------- -Jay
