    Took out my non working tach and finally found a so so replacement. Of course I have misplaced the original. Can anyone tell me which wires get connected where so I can install the new tach.
    Thanks for any help.

    there are only 4 connections usually negative (ground) positive (power)  signal (comes from ignition coil where the dist . wire connects ) & power for light you can probably look up the info from the tach . brand’s website keep us informed on your progress

    Ground (GND) to ground. Positive (red, +) to key switched +. Lights are a + wire from the dash lights or the headlight switch. Finally the green or signal wire goes to the negative (-) terminal on you coil. done.
