Any of these numbers will work
1L54-7H417-AC
1L54-7H417-AD
1L54-7H417-AE
Last two numbers are software revision numbers I believe.
Yes, the 4x4CM is a common failure but it has specific symptoms.
Good read here on this issue: http://www.ford-trucks.com/forums/64...problem-3.html
Check the fuses, I believe there are 3 or 4 that are used in the 4x4 activation

Oil pressure is operated by a switch on the engine, below 6psi if is off, above 6psi it is on.
So it isn't actual oil pressure.
If needle is bouncing from 0 to 1/2 then probably a loose wire on the sender(switch) or the sender itself is bad.
If it is bouncing 1/2 to max. then resistors in the gauge could be bad.
Actual low oil pressure will cause an engine "ticking" sound you can hear, valve train noise.
