As for the push button start switch. If you don't want to repair the wiring to use the key switch, one wire from the push button needs to go to a constant 12 volt hot and the other wire needs to go to the small "S"terminal on the starter solenoid.
And....
The GREEN with RED stripe wire coming from the cab connects to the 'I' input of the regulator.*Note*that if this truck was originally wired for gauges, the GREEN with RED stripe wire is sourced differently. If that's the case, you should make that clear.
The STA stud on the back of the alternator connects to the 'S' input of the regulator. If you have a factory electric-assist choke, the STA stud also branches to that.
The 'F' output of the regulator connects directly to the FLD stud on the back of the alternator.
The large output terminal of the alternator (sometimes labeled BATT or B+) connects to the battery side of the starter solenoid through a fusible link as well as the 'A' input of the regulator.
