Pertronix Ignitor to Ignition module wiring?

Ok, I bought this built 351W to replace my 302 and I'm wondering how the wiring is supposed to work? My 302 had a stock distributor with a 3 wire plug that connected to my ignition module. The 351 has the pertronix conversion and only has two wires and they both go to the coil. Now Pertronix shows to run a wire from the + side of the coil to the ignition switch in the picture below. Does this hook to the ignition module? Basically my stock ignition module has a 3 slot plug, and it sounds like I need to connect this one wire from the + ignition coil to one of these ignition module wires? Do I need the other ignition module wires? For that matter, do I even need the ignition module? This 351 was in a '69 bronco, and looking at their wiring diagram it doesn't look like it used any ignition module?

Thanks for the help!

your suposed to mount your ign module in the trash can when you get a petronix. :)
from the distributor, back goes to neg on coil. red goes to pos on coil.
hot wire from ign switch and resistor bypass goes to pos on coil.
depending on what petronix and coil you may need to bypass the resistor wire by running a new one. 12 volts all the time.

Great news! I've had two of these go out on me so I'll gladly pull it out (and save it as a spare for other bronco guys).

Thanks for clearing this wiring problem up for me!
