O2 sensors
is the actual sensor the same for a precat and a postcat o2 sensor? from pictures they appear to just be different wiring lengths.

2000 323i, so the connections are different and the length of the wires. what about the actual sensor itself? i have a bad front one and i thought maybe ill be able to splice a post cat into my precat since i did a rear o2 sim for my ebay headers.
