Don't bet on it, Ford is famous for changing wiring and connectors just for the hell of it. But if you took the whole harness, complete, it should swap.

very similar if not identical, depemding on how it was equipped. realize the underhood wiring harness should pretty much be identical in all dentsides depending on original equipment

Depends on the motor I would say as long as their the same motor you should be good.

Yes should be , there may be a few differenced if the dash is different
