Can anyone please help me with a dilemma? I am rewiring an O2 harness that melted near the manifold, and I can't seem to figure out the wiring diagram. This is what I have written down from the manual:

Front left Sensor
purple/brown-fuse 2
orange/white-ecm
orange-ecm
black/red-ecm

Front right sensor
purple/brown-fuse 2
orange/white-ecm
blue-ecm
black/red-ecm

What I need to know is what is the function (sensor signal, sensor ground, heater) of each of the ecm wires so I can wire to the appropriate harness slots.

 

Year/make/model/engine or post your VIN, so I know what I'm looking up.
