Sorry if this has been covered - I searched for it but it was a little daunting.

I'm in the process of putting my '35 big bolt back on the road. It has all of the original wiring which needs to be replaced. I am going to order spools and make my own wiring harness this winter. I'm not looking for 100% period correct but will match original when possible. It's a working vehicle that gets used for light jobs on my farm.

The cloth covering on my wiring has faded to an ash color so I can't tell much. Was the original cloth wire the "oak" color that I see from many companies? In the case of my grain bed with ground wires running to each corner light, were the ground wires a different color than the hot side?

Above the windshield I have a light bar with three lights on it. The domes are orange glass and match the bed lighting. Were these clearance light bars original or add-ones? My truck started life as a farm fuel delivery truck before grandpa bought it. They had put the grain bed on it to sell to him. I assumed that the lighting was a requirement going back to its commercial days when new.
