So yeah, my explanation was typed late at night and on my last trailing braincell. Probably not super clear. The CDI isn't passing power up to the switch. Just part of the whole circuit.
Battery > Engine Harness Positive 12v (red wire) > Ignition Switch > Black Wire 12v
The Black Wire 12v then splits into 1) CDI power and 2) starter button power.
So the CDI is getting switched power from the ignition key switch.
