I am running a AEM 30-4100 wideband in the car, I was planning on welding in a 3rd bung for this unit, however I was told that there might be some sort of pig tail that would come off the harness and hook into the factory O2 connector, therefore I would not need to weld in an extra bung.. I would just use the O2 that comes with this unit and then plug in the factory 02 plug into this harness.

The picture below is of the harness that comes with the wide band and there is a connector that has a cap that comes off that appears can be used to hook something else up to it. Does anyone know if this does exist and if so, what the PN is on it?

You can't plug any WB sensor into the stock narrow band connector. The thing the arrow is pointing to is the resistor that was installed with that particular sensor to calibrate it. To have the AEM simulate a narrow band you can set the output to nerst cell emulation and you'd have to splice the output wire (white) into one of the narrow bands. But IMO this is a bad idea. Also you would use up the one output the AEM has to emulate the narrow band so you could not send it to tuning software. Just weld in a third bung.

Thanks for the information!

I think Casper Electronics or Racetronix makes what you are talking about...
