    Any help is appreciated, I bought the tach below with the attached wiring. I believe at least the green wire is missing. So I have what appears one black, one white and one red wire. But the red is attached to a black wire... any informed suggestions welcomed.. FYI I bought it this way on EBAY, also it's going in a 1965 Ranchero 289 w/ 4 speed

    I just checked my 'spare' tach. 4 wires:
    White. Panel lights
    Red. Switched power
    Black. Ground
    Green. Coil negative side
    Yours is an autometer, you might try to contact them.
    I just checked the autometer site-their tachs all show 4 leads with the same colors as I listed above. Sorry

    Either take it apart and check the wiring, or better yet, send it back, because somebody has monkeyed with it - most likely why it was sold.
    Autometer won't tell you any more than DJ Clinton just did, and his info is correct.

    yeah I called autometer and was told it's basically a paperweight. The tech told me many years ago there was a tach similar to this but it required a type of sending unit. Thanks guys

    I have an Automeer I'm selling, it was for Babe, but with her disposition, I'd be willing to part with it, for the cost of shipping. PM me if you're interested.
