I hooked up my tach last night, unsuccessfully.... I did it like the shop guide showed, w/ the male prong going to an 12V ignition source and the other going to the resistance wire to the coil. Nothin'... Car would fire up and run, but the tach didn't register anything. The only thing I can think of is bad tach, anyone else have any insight, or know a place that does good tach repairs? Thanks!

Are you connecting an aftermarket tach or trying to convert to the factory tach? If you are trying to install a factory tach, there is more to the installation than that. Check the old VMF forum for a series of posts by Rich Pazjer where he pretty thoroughly describes the modifications for gauge and tach installation.

I am installing the factory gauges.... I looked at Rich's instructions, the 2 wires he speaks of tapping into are the resistance wire and what sounds like a + ignition wire at the fuse block... I didn't hook up the lights or anything else, just the pig tail coming from the back of the tach. Did I intrepret his instructions wrong? The way I read his instructions, I hooked one lead to a + ignition source, then the other lead ran to the resistance wire that I cut at the steering column.

It sounds like you hooked it up correctly. My tach did the same thing as yours: no signal registered, but the car started up just fine. If that is your case, then your tach needs repairing. I suggest Tachman at www.tachman.com

Hi there.
I'm having the same problem you did - and I hope you got it fixed or figured out. Can you provide me with whatever info you got to correct this?

Thanks!
