Confused on wiring. 1964 Barracuda.

Maybe PO did some creative rewiring and used existing wires to run other accessories?
Maybe. I'm not sure. As far as I can tell, they hooked it up like that for no reason. It doesn't go anywhere. There's no lights and the door switches were disconnected. I'm at a loss. I'll just leave them disconnected until I find something that may not work. Thanks for checking it out with me guys.
