Ford 4000 wiring diagram?

Can anyone e-mail me a complete wiring diagram for a 1974 Ford 4000 3cyl diesel tractor? I'm having to rewire the whole thing, dash gauges and all. Can see colors of wires in most areas, others are melted. Also, the ignition switch wires and what order they plug into on the switch. Any help at all would be much appreciated.
Thanks,
