Welcome to the forum, jacklan.
I've got the TC series repair manuals and when I look-up electrical I find a section over 200 pages long. There isn't one complete electrical diagram in the section, instead there are 100 or so pages dealing with specific circuits on the tractor.
I think you are better off explaining what problem you are having or maybe searching your problem from the archives already posted. Unfortunately our most informed mind on the TC series has passed away. Jim Inman (AKA , Jinman) was part of many, many posts with sage advice. In fact you will probably find an answer to your question somewhere in one of his posts. There are other members on the forum as well, that are good at answering questions.
