Default 68 speedometer with speed warning question???

I am in the process of rebuilding my speedometer for my 68 and it has the speed warning option on it. Can someone please explain to me how it works? Looking at it as I clean it, I just don't understand how it's supposed to operate? Thanks, Jason

havent seen one on a corvette but on a 68 GTO you would set the needle to a certain speed and if you exceeded that speed a buzzer would go off

Turn the pointer to the speed you want. Speedo will beep if you exceed the speed.

The AIM shows the installation. Can't recall specifically, but the owner's manual probably tells you how it works.

It's more a buzzing sound than a beep (like the key reminder buzzer).
Do have one in my 69, guess they are pretty much the same

It's the smaller cable to the left.


I believe this is the buzzer and that it wires into the fusebox with it's own harness. I don't have me AIM here or I'd get that info for you too.
