the 3 wire connector that attaches to the headlight SHOULD have a light green, black, and brown wire. If so, and if it is a painless harness, they will be marked every 5 inches or so. They will say high beam head lamp, ground, low beam head lamp. I would pull the headlight and see if the wiring is marked as I describe. If so, I would think the black will say ground, and be grounded to the radiator support close to the headlights. Just worked on a 50 Chevy with painless wiring and this is what I found.
