Default A4LD to M5R1 swap - 4x4-specific computer?

Al,

I have a 1994 Ranger XLT 4.0L 4x4 with an A4LD and electric shift 4x4. I want to swap to an M5R1 when the A4LD dies and am gathering parts. I have 2 questions about swapping the computer:

1) Are there 4x4-specific computers, or does the computer just need to come from a '94 4.0L Ranger w/ a manual (meaning 2WD or 4x4 is irrelevant)?

2) Does the computer care what transfer case I have? Will likely go to a manual BW-1354 when the transmission gets swapped. Will my "4x4" light still work?

3) What is EEC-IV wiring? I am looking at a computer from a '94 4.0L manual and it says it "Should be compatible with pre '95 4.0L Rangers with eec-iv wiring."

Thank you!
