PCM swap help needed
After many hours of ohming wires and checking circuits I have concluded I need a PCM. My question is: Which of the numbers on the PCM's need to match? Mine are as follows:
Motorola SN: 6FXF25N016S9
Motorola Model: 6FXF25NA32
Ford P/N: 6L1A-12A650-KB
Supplier: Motorola M799G
PCM U222 GNV1 5L28
Also curious as to whether anything has to be done about the PATS when swapping a PCM.
All advice greatly appreciated

You need: 6L1A-12A650-KB
The PATS is separate from the ECM and should not be affected.
Here's a used one from an 2006 Expedition for $80 with free shipping.

PATS is integrated between the HEC and the PCM. You cannot replace either without having the PATS system re-programmed, usually by a dealer.

Only insofar as the PATS has the ability to trigger the ECM into not starting. There is no PATS key code information stored in the ECM, that information is stored in the PATS module.

No, but the PCM and the HEC are effectively "married" to each other. You cannot swap either without reprogramming PATS.
There is no separate PATS module in this truck, it's function is integrated into the HEC.

My information said it's mounted under the RH portion of the dash behind the passenger airbag while the ECM is mounted in the engine compartment.
Now you've got me second guessing myself.
