Where are the oxygen sensors?

RE: Where are the oxygen sensors?
Guys, I think that the 4 O2 sensors are for the California market, the 2 O2 sensors are for the rest of the US. I just bought a 03 4.7l extended cab 4X4 and noticed that I had empty sockets in the fuse box for O2 sensor circuits. I found out that the 4 O2 sensors are a specific emission package, I assume for the CA market.
