The wireing harness if it’s a 2 slot door switch type is totally different to a uk single slot even if you got a complete uk door it’s not a straight swap
if You are wanting to swap a 2 slot import Italy I guess to run on uk single slot door with c120 or sr3 mech then you will have to swap the door and make a harness up
Chris is this the same with a 90s Williams I have a single slot coin door but no wiring or dill switch interface board ( is that all I need to swap ? )
