The new gauges have that factory look. To supply power to the OPG gauges, install the plastic connector that was attached to the old fuel gauge to the rear of the new fuel gauge. The new red wire supplies power to gauges on both sides of the cluster. Finally, reinstall the cluster and subsequent parts back to the dash. Remember to install all the gray wires and bulbs (dash lights) into the housing. This 67 Chevelle also needed a new speedo cable so we contacted OPG for the right part.
