oxygen sensor wiring problems

How do I tell what wires serve which function?

The wire colors differ from my ECU wire colors.

For 4-wire sensors... Black is the sensor output, gray is ground and the 2 white wires are for the heater circuit.

it does matter which white one is which. there's really no way to tell which one goes where except for the plug order.
