Thread: Making O2 sensor extension for headers - which wire goes where?

So with the header install I needed to extend the harness. I purchased a brand new O2 sensor from ZZP & extended harness myself.

However, extending the harness came with some problems http://www.grandprixforums.net/makin...ere-67540.html

Now I am getting code 1133, I ended up guessing which of the 2 unmarked white wires goes where - guess that failed or the extension is too long & throwing out bad readings? Anyone have a picture of an O2 sensor showing exactly what wires from the plub end go into what position on the sensor end?

I would hate to throw away a sensor with 50 miles on it.
