Subject: [TR] Installing Pertronix on a 74 TR6

Robert, I have a 72 TR6 with a Pertronix but 72's do not have ballast =
resistors. Therefore, I'm not positive of what I'm about to say, but it =
is my recollection that the ballast resistors in the later models are =
actually in the wire (positive, I believe) going to the coil. I'm not =
sure what they mean by "in front" of the ballast resistor.....whether =
that means between the ignition switch and the resistor, or between the =
resistor and the coil
