Pertronix install vs. wiring diagram

Hello electrical gurus,

I'm installing a Pertronix Ignitor (original, not II or III). I've confirmed the coil has adequate resistance, greater than 1.5 ohm across the poles when not connected.

Because the '67 'cuda has a ballast resistor (2 terminal), the instructions say to connect the black wire to the negative (-) side of the coil (easily done) and "connect the Ignitor red wire to the ignition switch side of the resistance."

So, I pulled up the wiring diagram for a '67 'cuda from this link, http://www.mymopar.com/index.php?pid=27 Specifically here;
Drawing A - http://www.mymopar.com/downloads/1967/67BarracudaA.jpg and
Drawing B - http://www.mymopar.com/downloads/1967/67BarracudaB.jpg

Now, Drawing B shows a large Dark Blue coming off one terminal of the resistor and going to the positive (+) side of the coil and the paired large Brown going to the ignition switch. From the other terminal, it shows small Dark Blue going to the Ignition side of the voltage regulator and the paired small Dark Blue w/ Trace going to the ignition switch.

Okay, now the problem, I'm stumped... Since leads from both sides of the ballast resistor go through the bulkhead to the ignition switch, which side side should I be connecting to, and where is the best place, underhood, to tie in, and not butcher anything? I think I have an idea which side, but I don't want to screw it up, void the warranty and waste my $90 some odd dollars.

Whatcha got for me?

Thnx, Mike in FL
