I'm trying to install an air/fuel monitor for my 2003 ram hemi. the
wire diagrams that I have found do not match my wire colors. I have 2
white, 1 black, and 1 grey. I need to determine which is the signal
wire. I think it is the black but need to confirm it. Thanks Art

The signal wire is tan with a white tracer

Didn't see a tan wire. Are the wires different on the other side of
the connector? They are covered and a just figured they were the same
color as those of the O2 sensor. Thanks I'll check.

No, those wires refer to the factory wires up to the connector. The wires
on the O2 sensor could be in any order. You'll need to peel back the
factory loom to find the correct wire.
