    Pick up the tach signal from the wire that supplies said signal to the cluster. Switched power is available from one of the "accessory" fuses next to the fuse box (the other is unswitched). Or you could pick up power from one of the switched supplies to the cluster. Ground can be had in a lot of places, one of which being the main ground point above the steering column.
    The car makes it possible, but the driver makes it happen.
