I was convinced that the short in circuit #1 was going to be an awful problem that I couldn’t solve, but it sent me on my way to solving that and other problems.
First, I thought it was going to be in the tail running light or the front signals, but nothing looked out of sorts. Then, my gut was telling me it was the license plate lights. Sure enough, when I removed the body panel that holds the license plate, the wire inside had been smashed flat such that the wires were exposed. So I ran a new wire. This solved the short and made me fix the lights that I had been avoiding.
Also, it had been suggested that I look at the rear junction box. This wasn’t a problem, but I’m certain it would have been soon. The lid wasn’t seated fully and one of the screws was missing. These holes caused the junction box to be full of dirt. I cleaned it and tried to put it back together. There were difficulties, but another issue has been solved.
And, as if that weren’t enough, the panel that holds the license plate also has a spar that goes into the body tub. I noticed threads at the end. Fortunately, there wasn’t a bolt in it because I don’t think I would have thought to look there while removing that panel. When reassembling, I put a bolt in that spar and it fixed the tailgate sag.
So, there it is, trying to fix one problem fixed a couple others.

Welcome to the fun of owning a used Pinz! Trust that once you get the collection of PO (previous owner) issues resolved, these trucks are pretty darn reliable. But they are also old, so those plastic and rubber bits will need some TLC from time to time so watch for that.

Glad hear you're making progress!

PS: Congrats on the muffler fight. Yes, it's a little fussy to get in, and it does require a fair bit of dexterity with the bolts. Another tip is to leave it loose in the supports until you get the heat-exchanger all bolted up. Then secure the muffler. That way there isn't stress on the muffler or heat-exchanger.
