Tony,
This is REAL tough to do long distance. Based on Brad's info above (thanks, Brad!), the actual wiring colors in an Avanti don't entirely correspond to the wiring diagram for an Avanti that I linked to and it doesn't appear that your actual wiring corresponds to either.
Is there any way you can just put it back to stock and then at some point in time, enlist the on site assistance of someone who has successfully installed Pertronix in an Avanti? Quite frankly, the stock, dual point ignition on your car is pretty good. You MIGHT notice a little easier starting with the Pertronix, but unless you drive the car hard and often, the advantages of the Pertronix (no points to adjust or replace, hotter spark) would probably not be noticed.
Disconnecting the wire that provides 12v when cranking is optional. I would do it just because it isn't needed with the Pertronix coil, but this isn't necessary. Brad says this wire should be pale green with a black stripe.
Brad confirms that an Avanti has a ballast resistor, not a pink resistor wire (it can't have both), so the info on Bob Johnstone's page does not apply to an Avanti (with the possible exception of the tachometer part)
The power wire from the ignition switch is black with a green tracer. In stock form, this wire is on one end of the ballast resistor and there is a red wire on the other end of the ballast resistor that goes to the coil. You can either put the black with a green tracer directly to the + terminal of the Pertronix coil, or move it to the same terminal on the ballast resistor as the red wire that already goes to the + terminal on the coil.
