    63 FI tach buzzer

    Hey guys,

    This is the relay that I assume goes to the tach buzzer on my 63 FI car. What I am missing is the buzzer and wiring. I looked on Zip Corvette and what they show has two wires. This relay has 3 spades. Can someone tell me what I am missing, and this is a mechanical tach, so where does this get the signal from? I have a new Lectric Limited wiring harness and I don't see any connectors in the harness that match this either. Thanks so much!

    Todd, That is the tach buzzer. I never knew what the additional terminal was for but it is not used. There is an additional harness required. This has to be purchased separately. It has a long pink wire to the fuse box and a blue wire that plugs into the back of your tach.

    Good luck. BTW, when you rev to 6500 to test them, the car makes more noise than the buzzer does!! Fun times!

        Thanks Joe,

        I see in the thread Don sent that guys made up this harness. I would prefer to purchase one that is correct. Where would you recommend purchasing this?

          I know that Corvette Central and Zip both carry this harness.
