[Gary]

That is true for the Ignitor 2 module,
I have a Pertronix 1.  OP has?

What one needs to be careful about is what side of the resistor the connection is made. As illustrated below the red wire from the Ignitor goes BEFORE the resistor and gets the full 12 volts.

I recall the rated working voltage of the Pertronix is 8 or 9 volts up to 12 volts and I presume they are able to ‘get by’ wired that way.  But from what I have seen on other sites that is not always the case.  I believe that IF you are using the Pertronix coil it is  true 12 volt coil with no external resistor. In that case the + side of the coil would not be an issue for the red wire connection point as it is getting the full 12 volts. Hence why some Pertronix instructions say to connect to the coil + terminal.

I have the red Pertronix wire lengthened and connected (also) to the ‘run’ side of the ignition switch as a dedicated connection.  I have been running it this way for 7+ years and have an “old school” Sun tach that does not exhibit issues.
