Yes, that's pretty much what I thought too, although there's more resistance across these terminals than I would like to normally see. Almost like there are internal resistors or something. Or, it could just be really old and corroded like everything else in this area. I haven't traced all the wires back to anything else to figure out what these actually go to, but two of them have jumpers that go to the terminals on the headlamp motor switch.
