Jay,
The pic below should help. The green wire with a red stripe goes to the "Gen" light in the speedo.
Those pre-made connectors should be available from some of the auto parts stores, and you can find them on eBay.
I, too, caution against using the stock Pantera wiring and ammeter.
You should consider adding a #4 AWG (or larger) wire from the alternator's BAT (output) terminal to the BAT terminal of the starter solenoid.
