Working on several wiring issues I believe I an induced another. Factory temp gauge and fuel gauge stopped working suddenly. Pulled the gauge cluster and found that previous owner had jumpererd the solid green wire to under the screw that holds the fuel and temp gauge in the cluster due to the printed circuit board being damaged near the connector. Question is, what am I looking for out of this green wire? The wire schematic has me thinking its +12V.
