A Navajo is an Explorer, so it's actually not a hard swap.
I assumed you were talking about a B-Series. You don't see many Navajos any more, so they slipped my mind.
You will need all of the wiring and the computer from the Navajo for sure. The transmissions should both be A4LDs though. If you can, just buy the Navajo so that you have a good parts vehicle.
