oxygen sensor

Hi,

Each of the colors goes to a different place. First, if you look at pic 1 below, I highlighted the sensor matching the colors you indicated. Now, for me to show you where they go, I highlighted each wire and need to include the entire powertrain management wiring schematic. It is six pages long and I have to cut each pic in half to make them readable. If you follow each of the wires I highlighted, you will see the purpose of each one. Start at pic 2.

If you are working on the wiring, here is a link you may find helpful:

I hope this helps. Let me know if you have other questions.

Take care,
Joe
