There is no power leaving the starter. Big honkin wire from the battery but that's where it ends.
There is power coming from the battery to a junction on the core support. From there it goes inside to the fuse panel and ignition switch. Because it's an HEI and trigger wire for the EFI, I can just steal that key on
Seems simple enough except I don't have any fuseable links or resettable breakers from the battery. Bender didn't have any either, never liked the idea but also I don't really know how to remedy it.
