NOS Tractor Wire Harness International 275277R92 Farmall? Original circa 1950s to 1970s IHC International Harvester wiring harness assembly part number 275277R92 in factory carton. I find no listing for this number but it is most likely for a tractor like Farmall. Bought at a farm estate sale and could not get info. It is in pristine clean condition and not altered or cut. It measures overall just over 9′ feet long all stretched out but divides for split locations. I have many photos so you can make out connections etc. Scroll own to view all 6 images.
