Mark, You may want to contact a salvage yard for your wiring harness needs.  It is difficult to obtain new items for these older machines.  I am experiencing the same situation for our 1981 F2.  If you are unable to piece out and repair the section of wiring you need, perhaps you can get that section from a salvage F3.  Worthington Ag. Parts is a good source with stores in many states.  You can google them to obtain contact information.  I was at the store in leesburg, Indiana yesterday and they had 3 F3 machines for parts.  Good luck.  Tom
