Bob G Do a ggogle search for 8n ford wiring diagrams. look for a 12 volt one for front mount dist since you have a ballast resistor. one wire from battery and one to the ballast resistor.
BobV_KS The wire from switch to alternator

Does this wire go to the big post on back of the alternator, or to a plug on the outer rim of the alternator?
