i think it may be easy.. check if theres a Yellow insulated cable in the location where it goes .... I've got a workshop manual here, and it seems the Airbag modules wiring are the same.. but hey, i'm no ford engineer. so dont do it based on my opinion.. do some research, get a workshop manual!!
BTW, the AU2 fitted with a pass side airbag will also have front seat belt retentioners (which are also explosive driven off the airbag module)
