Need help identifying what this connector is for.
 

Installing an aftermarket headunit and I'm trying to make sure I get all the adapters necessary and I have all of them but I'm not sure what this last connector's function is. It is a 10 pin connector.

I tried searching but couldn't find much for a diagram on a 2019 brz headunit.

Any help would be appreciated.

Edit: I also need help identifying what the grey connection is for.

better question is what do you need it for?

the gray connector ought to be the oem satellite radio antenna.

Thats what I'm trying to figure out. Not sure if its something I'm going to need to tap into or find an adapter that will let me plug it into the aftermarket headunit.

My car is in the shop getting some dents fixed, otherwise I would have the new headunit installed and would know if I needed it or not. Just figured I'd find out now and order any parts I may need before I get the car back.

shouldn't really need anything more than the standard harnesses. the metra 70-1761 will get you power and speaker connections.

they list 40-lx11, 40-lx21, and 40-lx31 for terrestrial radio antenna's, i used just the 40-lx11 in my '14.

they don't actually list anything for backup camera integration, but i believe the toyota-compatible axbuch-t36v would be the harness and 6v adapter needed.
