Pin 2 Black = O2S White (O2S Heater Ground)
Pin 4 Black with green = O2S Black (O2S Signal)
Pin 3 Brown with yellow = O2S Gray (O2S Ground)
Pin 1 Green = O2S White (O2S Heater Power)

Any help would be greatly appreciated

Note: The O2S heater circuit has two White wires. They are not polarity sensitive.

I take it this an upstream O2S, California Emissions.
