Sensor Question

The green wire is the O2 sensor where it connects to the ECU. The bear coper wire with the black sheild is how Porsche decided to jump the wire from one connector to another. Is there any reason (other than poor wiring or dirty connector) why the copper wire would read less voltage (1/2 to 1/3 less) than the green wire? It doesn't make any sense to me. I think that booth of these wires should read the same voltage from the O2 sensor. Next weekend I am going to connect a new jumper and see if I can correct this problem. I was just hoping that someone would be able to tell me why its set up this way.

Some people are like Slinkies. Not really good for anything, but you
still can't help but smile when you see one tumble down the stairs.
