Where is located the fuel pump driver module in a 2004 Crown Victoria?

The fuel pump driver module in a 2004 Ford Crown Victoria is located inside the car's main fuse box (Power Distribution Box - PDB). The PDB is usually situated under the hood, often on the driver's side (left side in the US). It's a large black plastic box with numerous fuses and relays. You won't see the fuel pump driver module as a separate, easily identifiable component; it's integrated within the PDB.
