TBI swap q's

[CheapJeep]

So, i was wandering around the junkyard, and i was wondering what the problem would be with putting a late 80's/early 90's F*rd TBI unit onto our beasts? They look like they are the same mounting pattern. I guess the major problem would be wiring it. (these are not the big injection unit, just the TBI units slapped up on top)
Seems liek it should be easier than modifying the cheby TBI.
