If after your installation, the gauge(s) are not powering on, we would highly recommend going back through your wiring on the gauge power harness wires. If you are using an expandable circuit to get power from your vehicle&#x2019;s fuse panel, ensure you have two (2) fuses installed. An Expandable circuit needs two fuses installed to work properly.
