I will run a Pazon Sure-Fire (PA1) ignition.
Here is the wiring diagram that I put together in my planning. The deleted circuits are noted in pencil, and the original coil, points, mechanical advance and condenser will be omitted:

Did I get anything wrong?
Should I do anything with the rectifier or zenith diode?
