Pin 3 – Black: Ground; connect to a clean ground, such as a factory ground bolt.
Pin 4 – Red: Gauge Power; connect to a circuit that switches on with the key switch. If the circuit does
not have a fuse or the existing fuse is higher than 3 amps, use a 3 amp inline fuse.

CARE SHOULD BE TAKEN WHEN ROUTING THIS WIRE FROM THE ENGINE COMPARTMENT TO THE
INTERIOR. SECURE THE WIRE SUCH THAT IT DOES NOT INTERFERE WITH MOVING PARTS AND USE A
GROMMET WHEN PASSING THROUGH THE FIREWALL OR ANY SHARP EDGES.

block or by connecting directly to the wire running from the dimmer on the headlight switch.
