If your adding the Tik Tom Tach, the wiring for the dash lamps and clock should be already there. Look for a gray wire behind the dash, that is the wire for the dash lights. There should also be a orange wire, that’s battery power for the clock. All you need to do is run a wire from the tach terminal of the tach to the negative side of the coil. If I remember correctly there is a 2 amp inline fuse on that wire.
