Is there a difference between the four? Are the two back ones monitors for the cats, and the other two are actual O2 Sensors? Is there anyway to tell the difference between the two? Thanks.

Seeing as how I just changed mine yesterday, I'll chime in.
You have 2 blue connectors behind the cats and 2 green connectors in front of the cats. The fronts are the actual sensors while the backs tell the computer if the cats are junk or not in simple terms.

Also, Ford has 2 different p/n for the sensors, but all aftermarket manufacturers use the same p/n for all 4 positions.
