Headlights not working!!!

[DroppedC20]

Just picked up a 67 C20 and the wiring is honestly a cobbled mess. Can't get headlights to come on with either the bright or dim mode and I don't believe there's a headlight fuse on these trucks (?). Any common things on these that could cause the headlights to not work? I'm absolutely not an electrical magician so to chase down the problem on my own could take forever. There's no taillights on the truck right now, could that cause an issue? I do get front turn signals though if that matters.

At some point I plan to replace the wiring harness but at this point I just want to get the truck road worthy ect before I REALLY tear into it. Here's a couple photos of Chloe!
