Seen a few guides on retrofitting mfsw to non mfsw cars, however i have a 4 spoke wheel on my golf and was wanting to change to the 3 spoke found in the match models and gt spec cars

I’ve seen a few on sale including the airbag but was wondering would it be a straight fit?
The steering wheel should be as i’m not fussed about the buttons on them, but the airbag will also have to be changed from my original 4 spoke to the 3 spoke airbag

Will the airbag just be a straight fit with no difference in wiring or coding?
Or does it require extra work??
