For a follow up...all the assumptions were correct. The two big wires do in fact go to the fuel pump. The rest go somewhere else except for two of the others that go to the sending unit. There is another plug that the four wires come out of, but it is not accessible until the tank is dropped down pretty far. So the combination of wires in the seven wire plug come from either the FPDM or the CCM or a combination of both.
Kinda aggravating to figure out because the Haynes manual I bought specifically for this job DOES NOT include the wiring diagram for the returnless fuel supply with fuel pump driver module and fuel rail transducer.
Long story short, it took three hours by myself to drop the tank, remove the faulty one and install the new O'Reilly supplied replacement. $227.00 for the pump and a trip to the local Ford dealer for a replacement fuel nozzle grommet that must be cut out in order to remove said nozzle without damaging the on board check valve. Little chunk of rubber was pennies over $20.00.
Primed the system with a few key twists and hit the starter and she is purring like a kitten.....an expensive kitten though. Can't imagine the repair cost at the dealership !!!
