Dashboard covers and airbag V70

Hello guys, now that I have found a dashboard top in better condition, of course used, for my elk, two questions arise for the conversion: 1. Should I screw the airbag from the old lid into the new top for safety considerations, or can I just connect the airbag with the new lid like this? After all, I read on the airbag “not…into other vehicles” – probably this means cars from other manufacturers, so without SRS? 2. Einfac h so join me however presents itself as a problem: Which of the two plugs I open most meaningfully and how? (see photos) Thank you and greeting, Detlef
