My car has had no front o2's on it for about a week (don't ask), and the shop told me the wiring looms were different colors to identify which banks they belonged to.
They don't.
The looms to both front and rear pre-cat o2's are both black, so I have no idea which sensor to connect to which connector.
Can anyone help me?

I'll check the Bentley for you when I get home and see if there's anything in there. Be around 6p eastern.

I just had a customer asking me this. The Bentley states in a caution box. "Label connectors so that front and rear connectors are not mixed up"

Here is a picture of a post cat o2 sensor
Pre cat 02 sensor.
The plugs are different. Do you have the old O2 sensors? If you do I could look up the part numbers for them to see which one they are.

Typically the ones with the longer wires are the post-cat, no?

I have brand new precats at home. Would pics of those help?

No I need to distinguish between the "front bank" and "rear bank" PRE-CAT o2 sensors. The old ones were cut off by the PO to lengthen them, and were gone when I got the car. The wiring looms are both the same color between the front bank and rear bank FRONT o2 connectors, so I can't go by color.

Anyone who could take their engine covers off and tell me which connector goes to gray and which one goes to black wiring would earn an e-beer from me!
