Default Three Oxygen Sensors??

Can someone please direct me to a wiring diagram that shows the THREE oxygen sensors in a 2000 California Automatic? There is one at the manifold, one at the downpipe, and one at the end of the second cat.

Thanks

Found one. Harness for 2000 has facility for all three, but connects only two based on whether CA or not.

Interesting, 99 harnesses only have 2 connectors in them and are different for CA vs 49 state. the bung for the sensor in the 99 CA midpipe is omitted as well.

ZGA. California/Federal Emissions Conversion - Mostly MIATA

this article may be of interest to you. not a wiring diagram, but good for if you wanted to upgrade or relocate the O2 sensor the rear.

I haven't done this myself yet, but will be doing it soon

Thanks, that article helps. On another CA 2000(friend's car) I made up an extension to go from the plug for the midpipe back to the rear rather than trying to trace the wiring.

Probably would have been easier while I had the harness completely out, but now I am thinking of doing the same thing with an extension. This old body does not work well under the dash.

For those interested, I am just completing putting a complete auto CA 2000 into a 1999 shell. My Grandson doesn't drive stick and he wiped out the complete driver side of his car. You could not pay me enough to do this again.
