4000 ford tractor?

Hello,
I had a tractor catch fire just sitting there, has not been started in 3 days and it caught fire. I was wandering if anyone has the wiring diagram so that I can try and rewire it. It would be greatly appreciated if anyone can help. It is for a Ford 4000 diesel 3cyl. My e-mail address is tllys@aol.com
thank you
