O2 sensor difference?

I tried searching first but didnt find much on O2 sensors as far as what im trying to find out. On the O2 sensors side, are the 4 pins as far as function in the same location for both the Mark's and the Birds? I know the part numbers are different and was wondering if that has to do with how theyre pinned.

I'm not sure theirs even a part number difference. if their is, its probably a difference in length of the wires, or maybe an update to the sensor itself for more efficiency. otherwise its just two signal wires and two heater wires. suppose its possible ford mixed them around just for giggles, but i doubt it.

fordparts.com seems to think its F5MF-9F472-AA for both. at least in 97. for 95s its a different number F4ZF-9F472-AA,AB they physically look the same though.

wonder if theirs a difference in the manifolds, or pipes....i wouldn't think so, its a modular 4.6 with the same driveline underneath. well except the DOHC to SOHC

They are pinned the same, but they have different connectors front / rear.
