Agree with your scenario.

Originally, I was going to suggest the easiest and safest way would be to run both new wires but with the one available for sure under the dash, didn't think about it much more. You can pick up either 1D or 1F from headlight switch or ign switch for one terminal as you plan. The problem trying to use the other original wire is finding the splices without totally tearing up the loom. Packard shows them schematically but as many have found, they can be several feet away from where you would think looking at the schematic.

Would suspect that one in question is under the dash since by moving a couple of wires there they could go to either the 1 junction or the 2. Having said that, Packard manufacturing may have found it easier to place it somewhere far away where there is not as much bulk. If loom is accessible and you can pull off a foot or so of wrap, might be worth a look.

If that doesn't find it, then think I would use a complete new wire for the other. Cut, tape, abandon the light bulb wires and also the old 1C at regulator would be my suggestion. Pick up some non-adhesive harness wrap and just wrap a single wire outside the original harness leg to the regulator.
