Wiring harness a couple random wires?

Hey everyone, I’m back with more questions. Last night I sat down for an hour or two with each of the different wiring harness is. Had my wiring diagrams and was able to go through and label 95% of things. There’s a couple wires on the DASH harness that are cut. (A red, brown, dark blue/white tracer off the ignition plug, 3 orange together, black near the head lamp connection. If I’m correct the orange wires are for the lights on the instrument cluster. There’s also a thick black and red each with a small island connector. Didn’t find those on the diagram. Also one single looks like brown with white tracer with a small plug on the end of it that I could not find. Any help would be greatly appreciated

The heavy gauge red and black go to the ammeter.

The red one with the "elbow" on it is likely to the cigarette lighter.

There were also a couple of random wires I had with it that must’ve been disconnected when I first took it apart. Any help with these would be greatly appreciated.

The two left side photos are for radio speakers. The photo on the right is a non factory wire.

The photo on the right looks like an aftermarket speaker wire that someone spliced into the female plug.
