Unknown plug in passenger kickstop?

There's a wire connector with 2 wires going into it that's not connected to anything. It comes out of the harness in the passenger kickstop that goes into that fuse/relay box, but doesn't plug into anything. Any idea what this is? I've got a few random electrical things in my car that just aren't working, so missing plugs give me hope.

Might be for the system 10 door speaker, if you dont have system
10 installed then it wouldnt be used. One possibility, if my car wasnt
completely in pieces I would go out and take a look but I remember that
the harness from the amp to head unit has a connector that goes into
harness at the passenger kick panel
