Fuel Gauge wiring
Can anyone tell me what each of the four wires that plug into the top of the rear tank do?I need to rewire the fuel gauge to just the rear tank and wanted to know how to "wire it up"?

2 Blacks are grounds
1 (Black/Red ?) pump motor
1 (Yellow/Light Blue ?) to gauge
The last two go by way of the Fuel Tank Selector Switch.
1972 No pump, Two wires, one to ground and one to gauge.
Some older 460's around '83 had a pump in the tank also but I do not know what year that started.
If you jump the gauge wire from one tank around the Fuel Tank Selector Switch and disconnect it from the Fuel Tank Selector Switch it will always read the same tank.
