Think I have it partially figured out, first off, there is one extra blade on the switch that isn't used, weeding my way through the wiring diagram, going to finish removing the dash to properly diagnose my wiring, looks like some splicing was done around the headlight switch, looks like the switch itself has already been replaced recently, seems to test ok, may still be bad, I'll get the wiring sorted out first.
I may in the future, write a new wiring diagram, I have several programs to assist me in doing this, I've recreated several motorcycle wiring schematics in color, I think I'll do the same for the 72 Charger/Coronet as well, but may be some time till I get to it. When I finish it, I'll post it for all to look at and judge for errors, I usually will make an extra large laminate version for myself, who knows, maybe I'll get into making various ones and sell laminated copies.
