Re: 1964-66 Cluster Tac and Vac

I've long wondered how its possible for so many tach clusters to be removed from C60-80 series trucks by every Tom Dick and Harry and somehow none of those people ever get the tach wiring harness out of the truck with it. You assume if the truck survived this long with a tach in it, it has to have the harness as well....seems weird to me you can't buy a tach cluster that has tach wiring

I don't know what the aftermarket wiring harness look like for a factory tac. But the tac are only two wires one for the power and the other to the distributor. You can run your original harness or aftermarket with two wires.
