Gauge Installation on a Gen 2 Dodge Cummins

Once you've identified the correct illumination wire, install a red wire tap connector to the wire. Align the metal fork in the wire tap under the center of the wire. Fold the other half of the connector over, and while holding it in place, snap it completely closed with a pair of pliers. When ready to make the connection gather your illumination wire(s) from the gauges and cut to length. Install a male spade connector and insert it into the wire tap connector as shown.
