BOSCH 4 WIRE O2 SENSOR DIAGRAM

Can anybody check a 4-wire Oxygen Sensor?
ATS can give you the wiring diagram to check so you don't have to guess. The other 2 wires are your signal and power source wires either from the sensors and the computer. How to test the 4-wire sensor: Preliminary checks: Get a visual inspection on the way this 4-wire harness wire is routed and specially the way it is grounded.

Do I have to rely on wire color to correctly wire up an O2
It seems that everyone and their grandmother has a different color-code convention for 4-wire O2 sensors, which complicates matters when one is trying to wire up a replacement "universal" O2 sensor. Is it possible to determine signal-wire polarity on a 4-wire O2 sensor without relying on wire
