Wire and pin layout for rear view mirror?

Hi Guys, forum newbie here, I have a 2016 A3 8v, and my car does not have an auto dimming rear view mirror (The handle to flip the mirror broke off, so I don't even have that at the moment). I read in a few threads that the car may have the wiring for an auto dimming mirror if it has the rain sensor, so I popped the piece out of the headliner and saw the cable in the image. Is this for a rear view mirror? It wasn't connected to anything, and it's just taped up. Also, I am looking for some clarification on the pin layout (if it's for the rear view), whether it's pin 2 or pin 3 that isn't occupied. Thanks!

Also, sorry if this topic has been beaten to death. I've looked for days now and can't find exactly what I'm looking for.

I have the full electrical diagrams for practically everything.

Let me know if you need it. It is VERY comprehensive.
