The swap is easy...I did it for a JDM wheel as well. Disconnect the battery, take the air bag screws out, unclip the airbag, loosen the wheel secure nut but don't take all the way off, a few hard jerks and it will pop out, take off the nut and remove the wheel. Put it back in reverse order.
I don't know about the connector for his airbag but mine was plug and play.
