I have not been in there for a while so I'm going on memory. The headlights definitely were one wire to the left headlight and then across the front to the right headlight. This wire went to one end of the resistor--on High the voltage by-passed the resistor and went right to the pin. The two wires on the other side should be the flasher and the tail light. That pin gets 12V+ on both D and H but not R (or O, obviously). Then one pin and wire for the rear bright light and one pin and wire to the fuse.
If I did a rewire and it were not a show tractor, I'd just start from scratch with some split loom rather than making the wrong old harness work. I rewired mine from scratch when I was 17 and I'm 55 now and my old work has held up better than those IH cloth harnesses ever did. Plus it was easier to upgrade to an alternator and put in high wattage headlights.
