Bypassing Transisitorized Ignition on '65

My 1965 convertible came with the transistorized ignition. When I purchased the car, a prior owner had partially bypassed the system. Some wires were connected, others were not so I've always imagined that the original setup must have been causing problems. Unfortunately, I don't fully understand how the modified system was rigged (no condensor, original transistorized-only coil, negative post on coil had a permanent ground, lead from points went to a positive connection).

I recently decided to install some modern Petronix ignition components (wires, FlameThrower II coil, & Ignitor II electronic ignition). For this to work, one needs a more traditional ignition setup. For this to work optimally, one needs to also bypass the ballast resistor setup.

Here's what I did:
1. disconnect remaining wires from transistorized ignition
2. at the old transistorized ignition site, connect red/green ignition wire to blue/white wire (which was connected to the positive side of the coil)
3. disconnect the permanent ground on the negative side of the coil
4. hook the positive/negative leads from the Ignitor II to their respective posts on the coil

Now whenever the ignition switch is on, the power is feed to the positive terminal on the coil. Not sure exactly how the Ignitor II works, but I imagine if the rotor is rotated to a firing position, there is also constant juice to the coil (or maybe the Ignitor II takes care of just sending a single burst of juice to the coil and then breaks the circuit).

Now to my question:
1. does anyone see a problem with connecting the red/green and blue/white wires for supplying juice to the Ignitor II/coil? (I think the red/green wire might originate at the igntion switch)

As usual, many thanks for reading.
