Map lamp location

So I'm working on Daisy (my 73 dart 4 door and soon to be family daily driver) and there is a problem with the map lamp. the previous owner did some . . . .well. . . fun. . . wiring that I've been trying to figure out. Most of it has been fairly straightforward forward, but one head scratcher is this dang map lamp. So it looks like the last guy just wired in a random light socket and left it hanging. I was wondering if anyone has a picture of where it is supposed to be so I can get that all buttoned up.
