72 Swinger - Some wiring questions.
I'm currently cleaning up all my wiring and connections, fixing things that need fixing along the way. The FSM (for a 72 Valiant) wiring diagram has been extremely helpful, though it's still a tough slog. Someone did a crappy black spray bomb in the engine bay a long time ago, covering the true color of a lot of wires. And there's a lot of grime under my hood -- I've been too busy driving this car for the past 20 years to worry about cleaning anything -- it all just worked dependably. But it is pretty wretched in there. I want to tidy it all up before I do a red spray paint job on the engine bay.
There are certain things that I'm having trouble identifying. Any help is appreciated. The pictures are marked with numbers for reference:
1) There is a small sub-harness coming off the passenger firewall that isn't plugged into anything. Three wires (two are on the same terminal). They all appear to be blue(!!). At the firewall, these wires bundle with the wires coming off mystery item #2.
2) This thing is attached to the cowl on the passenger side. As mentioned above, its wires bundle at the firewall with item #1 above.
3) There is what looks like a dark blue wire coming out of the bulkhead connector. In all the years I have owned this car, it has just dangled, unconnected to anything. I've confirmed that it is switched power from the ignition switch. In looks like position N in the bulkhead on the wiring diagram, which would split and lead to the ballast resistor and the alternator. But again, the car functions as it should, so there are no known symptoms related to this not being hooked up.
Thank you in advance for any insight or ideas.
