Yes wiring, especially retiring can make your hair grey in no time. There is no simple answer to your needs. You are going to have to take a diagram for each part, (Kohler, Kawasaki and Bobcat) and figure out where each wire cam from and go to. That is what we as techs have to do in your situation. It takes time and patience, which is why it costs so much to do what you are trying to do.
