CHI2,
I recommend that you install the PAMCO first and just temporarily wire it to a seperate battery sitting on the floor. This approach has a couple of advantages:
1. Enables you to use the stock rotor for timing reference before you remove it.
2. Provides you with a running engine so you can test the PMA setup before you commit the ignition system to it.
3. If you have a capacitor setup for the PMA and there is something wrong with it, you will not be able to start the engine to trouble shoot the PMA problem.
4. Protects the PAMCO from very high or erratic voltage from the PMA which sometimes occurs due to incorrect installation. In some cases, it's possible for the PMA to produce up to 20+ volts which will fry the PAMCO, so its good to find this out before you wire the PAMCO to the PMA.
