Stock GM Oxygen Sensor Wiring for 86 S4

[deecee]

I shortened the cable to the O2 Sensor on an 86 S4 and now I'm trying to find out what wires go to what Pins at the Harness Connector to the Stock GM 02 Sensor.

The choices are on the ECM Side:
2 Blacks
1 Green
1 Brown/Blue (Shielded)

The Choice from the O2 Sensor:
2 Brown
1 Purple
1 White

Daryl
