Massive problems!!!
google it, lots more info on this swap in mustang forums.
Just asking out of ignorance here, but would it not be easier to take the newly installed engine back to a pre-computerized ignition and carb set up than to go through with the electrical nightmare? I have thought about retro fitting my 4.9 to mechanical and carb. I'm sure that there are certain laws about this, but my question is about the ability, costs, and difficulty of the retro fit. It would seem to me that if local laws didn't prevent it, that this would be the easiest way to do the motor swap, and probably cheaper than putting the computer and all the sensors in, drilling and tapping the holes, chasing the wires, and getting them into the correct points in the harness.
