I checked with Ford Dealer today to replace the cover for the Passenger-side Wiring Harness (on the firewall near battery). I was told that I would need to spend $795 and buy the entire harness to get the cover. Any parts guys out there who can verify or PoohPooh this info? If so, got a part #? I will check wrecking yards, but thought I would try for a new one.

 

Might look around the dealership and see if you can spot a part number.

Ford is good at not breaking out the part numbers, but if you get one of them then it will lead tot the others.
