I'm not sure on this one. I've never been around an internally regulated Delco that had color coded terminals. The ones I've been around had the 2 connector plug plus the main battery feed. Sorry I can't be of more help here. Maybe someone else has run across this.

I am not familiar with your current setup, but I recently rewired a 640 series from 6volt to 12volt. The installation is simple, but the wiring can be confusing. If you have a "self energizing" Delco alternator, you need only run a wire from the "Battery or Bat" terminal off the back of the alternator to your ammeter or voltmeter. If this is a conversion to 12 volt, you will need a resistor between the switch and the coil, as well as a 12 volt coil. The alternator should begin charging once the rpm's get over about 1200. If it does not charge, you will need to run a wire to the terminal marked #2 on the top of the alternator from the side of the switch that is hot when the key is on. Be very careful to not blow up your battery with a spark while doing the rewiring as it can be very volatile. This magazine also has an excellent method of wiring the system and making it much safer, listed under 12 volt conversions. Most folks opt for the Delco alternator, unfortunately, you can't tell by looking at if whether or not the internal volage regulator is "self energizing".
If the system does not throw a charge (which is hard to detect with the ammeter), then you will have to add the additional wire to terminal #2 to excite the regulator and allow it to charge.
