Re: Factory Tach Install
Make sure the ground straps are in place from the engine to the firewall.
The gauge housing can be grounded to the metal part of the dash with a short length of black wire, (black is the standard color for ground wires). Using terminals on the wire fasten one end to the housing with one of the 1/4" headed fasteners.The other end is screwed to the metal part of the dash.
