There are four wires.
1st-Black wire goes direct to the battery. That's the alternator output.
2nd-Black/White wire is switched from the ignition switch to alternator.
3rd-White/Black wire goes to the charging warning light in the instrument panel.
4th-Yellow/Blue wire goes to the carburator electric choke heater.
Alternator body to ground.
Now I guess you can figure out what you need.
