Jay, The Pertronix ignition module has its own current limiting resistor (ballast) inside the module. So you don't really need the one at the firewall. The device works on the Hall effect principle - the module is converting magnetic energy into an electronic pulse. There is a magnet that is embedded in the piece that came with the kit that slides with the rotor. That magnet passes by the module as the piece rotates with the distributor shaft. In other words, the ignition module senses the magnetic field of the spinning piece and acts as the point contacts to the coil. I digress, but anyway, removing the ballast resistor from the firewall won't harm the device. Keeping it if you want a purist 100% stock look shouldn't harm things. You will have slightly less current to the coil, so it may act as a poor man's rev limiter.

I just bought the Ignitor II electronic ignition setup for my 64 Iml 413/ I've read everything on the IML website, but still can't find an answer:
1. Pertronix says to run the red module wire (dist +) to the ignition side of the ballast resister (passenger side or driver side?). Then what - run another wire back to the coil?
2. They, however, recommend that the ballasr resister be disconnected and the wires connected to eliminate it entirely. If I do that, the red wire can go directly to the + side of the coil.
The question is: if I do bypass it
entirely, what, if any, problems will I experience? I know the ballast resister is to protect the points, but if that is its only function (since I'm dumping the points) then am I oorrect in assuming that it is OK to bypass the ballast resister? And, (I'm real dumb in this area) if not, what side of the BR does the wire go to and is that the only connection?
Thot I'd ask those who have been there and done that.
Thanks,
Jay
