Hi everyone.

It's been awhile since my last post, been busy buying a house and working on a "new" project!

It's a 1979 210 4 door sedan. Maybe not the prettiest of body styles, but it's growing on me. I'll have some pictures soon.

My question is-I've installed a factory tach, which plugged right into the wiring harness behind the dash-but no worky! Am I missing something? I can't seem to be able to find a wiring diagram for this this either.

Any and all help in this matter will be appreciated!

If no one responds before I get back to California I'll get you an anwser and the wiring diagrams out to you nxt week. You said factory which I assume to be stock. If it is after market, no sweat-got that covered too.

Thanks for the help! I'm going to be able to look into the wiring very closely in the next day or two-I'll post with the results!
