1997 4.0 SOHC Minimum to Start and Run

[McClellanSean]

I am doing an engine swap swapping in this 4.0 SOHC from a 1997 Explorer XLT. As I have begun the start there have been plenty of modifications and frustrations as it takes some fabricating to do the swap. I am quite close to getting everything back in and I feel like I am just about in a place to start the engine but I was wondering what is the minimum wiring and mechanical needed by the pcm to start and run the engine so I can hear that satisfactory engine running.

Power to the pcm and sensors, power from ignition source, fuel pressure and oil you should have a mas sensor in place and at least two upstream oxygen sensors
