1979 F350 Dually with dump bed

I need the wiring diagram that tells you what wires hook into the externanal voltage regulator, and what goes to the alternator, wiring is all messed up...... when the alternator is hooked up, voltage surges blow the voltage regulator, and then fry the ignition module. Please help...

Anybody know of any fixes, also have the idea of swapping a wiring harness from a 1977, same engine, diff trans, into it. Have all the complete componets there, thanks alot if anybody can help me.
