What is this - vacant plug & box behind Glove Box?

Hey there …. First post question
we bought a used 22 Ryker 900 sport from a dealer for my better half. I know next to nothing about them so it is a learning process for me. I pulled the glovebox to put some LED’s and I found a plug unplugged on the backside. What is the small rec box for ?
Any insight for me?

Thank you
Ray

When connected your locking trunk will only open when the Ryker is running and locked when engine is off.

Thank you
It was already unplugged when I removed the box
