Now I'm lost.
I thought you were looking for a switched power source to turn on the box?
Are you now asking about the main power? No switch, no fuse. Direct heavy wire to a power source.
Mallory shows it to the battery, but note it can be any place in the line such as the starter relay (or for a Ford, the solenoid).
Also on the first page it says it does not matter if the ballast resistor is present on not. So its same as the MSD
This diagram is most representative of a Chrysler distributor.
When it says ballast not used here, its in reference to the coil. The Hyfire needs to be directly wired to the coil - no ballast in between.
