I am looking for the part number for the wiring of the second O2s after the cats. I will be buying the euro headers and would like to just buy that piece rather than doing all the wire extending.

Thanks for your help.

It's not that simple... You see there are only two option extend the sensor or by the Euro Engine wiring harness or maybe drop the US harnesses down. There is SOME slack in cat monitor sensor harness that will allow you to drop them down near the cats, but I'm not sure it'll be enough. I have yet to try honestly. Regardless if that doesn't work you will need to extend or buy the euro loom, also don't forget the EGT sensor.
