Interior Dome Light Question

[nuvolari]

I have a 00 986 and my interior light and alarm sensors are broken and not working so I picked up the pictured item at the junkyard from a 03 model. So, a couple questions:

1) Will this work for my 2000 model? I think my light is different but near as I can recall, the main housing and alarm sensors look the same but forgive me as I haven’t seen my car since Dec of 2021.

2) What’s the deal with the light? It seems to have a sensor of its own and possibly a push button.

Thanks
