Hey guys. I have been tinkering with my stereo system. I am about to install a GROM Auxiliary jack, but as I was messing with my dash, trying to figure out where to put everything and how to install it, I ran across this plug, but I have no idea what it is for or where it goes. I've tried to follow it with a light and mirror, but without further dismantling my dash I can't figure it out, so I was wondering if anyone can tell me what it is for.
The first picture is of the small removable panel in the red circle and the second pic is of the panel gone and the plug sticking out.
