It is in central junction box, but may be part of it and not serviceable. See picture.

Computer problem
2000 Ford Expedition Engine Size unknown All Wheel Drive Automatic 120, 00 miles

had just bought this used from a lot, and only has one key, the remote is broke, and I need to know where to locate the computer to get the manufacturers pass code to set the keyless entry numbers for our use. I bought a manual and it tells how to program, but doesnt mention where the computer or number is located.
