If you haven't guessed, the Haynes manual's wiring diagram is VERY wrong especially for US 1500's. Tom O'Malley has spent many hours redesigning wiring diagrams for maximum readability. They are the best diagrams I have ever seen saving me many hours troubleshooting. So good I wish I had thought of them. Tom, if you are out there, email us!

Since many manuals show the diagrams differently or poorly I have shown all options from all manuals I could find.
