[Classic Mustang] Re: 6 Cyl. Intake Manifold Rear Freeze Plug

Neal,
As you stated, the Pertronix needs a good 12V source to operate
properly. The original wire from the ignition switch to the coil has
a resistance wire (pink, under the dashboard) spliced into it so that
when the engine is running, about 5v is supplied to the coil and
points.

If you retained the OEM coil and just replaced the points & condensor
with the Pertronix, you'll have to run another wire from the back of
the ignition switch to the Pertronix. Splice that wire in between the
switch terminal and the pink resistor wire. The new wire will give
12V to the Pertronix while still suppling 5V to the coil.

If you have a 12V coil, you can remove the resistor wire and replace
it with regular wire, I'd guess about 14 gauge, so both the coil and
the Pertronix will have 12V.
