Normal routing of headlight wires

[dmjlambert]

Hi folks, what is the normal way the headlight wiring would have been routed for a 1963 C10? As you see right now it's probably just table lamp wire draped across the bumper brackets. And there is a ground wire coming out of a gap near the radiator and wrapping around the main negative battery cable and attached to engine. Looks funky to me and I'd like to straighten it out. The main charging cable between the horn relay and battery look pretty good, it's going through holes on both sides of the radiator support and going through clips under the top of the radiator support. I wonder if the headlight wires used to go along that path. What's the most proper way?
