VXOC Astra-J/GTC

Hello everyone this is my first time ever owning a Astra or a Vauxhall come to think of it. Anyway back to my question What is this connector for? I have an Astra J Sports Tourer 13 plate with a CD 400 If that helps. 

That plug is used rear 12v socket, ambient light around the gear knob and other things.

Thanks for that now i know what its for.
