Since the O2 sensor gets its ground from the exhaust pipe the signal will remain after the connector is removed. Ground one end of multimeeter to the door stay and mesure the voltage. The reaction in the O2 sensor will continue for a few minutes while it cools off and the exhaust gases disapate.

I doubt that the copper is an EM sheild. The schematic shows the O2 sensor jumped to pin two, and it is not set up as a sheild. It appears that instead of jumping the wire Porsche decided to try this way of splitting the wire to two different connectors.

Thanks for the input.

I am still not sure about this yet its just my .02

still can't help but smile when you see one tumble down the stairs.
