I thought that was what you were asking in your initial post. The 6V/POS GRN system using one wire, the HOT (-) wire to the lamps. The GRN (+) wire is connected to each lamp internally to the shell metal ground. You just need to ensure all rust, paint, and crud is removed to make a solid connection. I don't have my Halls easily accessible so can't get out mine and take photos. N-Series Headlights were never installed at the Rouge or later, the Highland Park) plants. Lighting kits were only offered as dealer supplied optional accessories. You got two headlights and one tail light with all the needed hardware and wiring. There was a wiring diagram included. I have one -see picture but if you want a hard copy, email me and I will send one to you. The sketch is 17 x 22 or so too large print here.
