1973 Duster Fuse block mounting

Hey, new member here, and new to A-body Mopars in general....have to confess I'm a hardcore Pontiac guy. I have a 1973 Duster in my garage at the moment that belongs to a friend. The backstory is he got it as an abandoned project; it's one of the nicest project cars I've seen, straight as an arrow & not a speck of rust. BUT....someone else stripped it down. One of the things they did was to pull the fuse block out - it was taped to the e-brake handle, along with a coiled up harness that i think must go to the rear of the car. I've got 2 questions:

How / where is it supposed to be mounted?
Does the rear lamp harness run thru the track thing that is next to the door opening?

If anyone has pictures that would be great...I should note that even tho the fuse block is not installed, it is still hooked up. I can't test much as far as lights, etc. because the car is so stripped; the car starts, stops & the guages appear to work, so thats a start...
While waiting for one of the guys to find some pictures, you might want to check the mymopar.com site. The reference section has downloadable service manuals for some Plymouths and I saw the 73 dodge manuals are there. The Dodge Dart is the same platform so you can find a lot of info for reference. I think the wiring diagrams are also there for trouble shooting the circuits.
