Last winter, when I was taking my truck apart and I made the electrical drawings, I found my headlights to contain both Packard and Douglas connectors. I was curious about this at the time but put it aside. Now, as I reassemble, the subject has come up again. My wiring harness has Packard connectors to the headlight pans and then Douglas connectors to the lamps. Since all new Mil-Spec head lamps have Packard connectors I wonder if they once had Douglas or my truck was modified? The PO spliced the wires to Douglas connectors so that muddies the waters.
