Hmm. Not sure what's going on here.
Yellow wire still attached to starter (that may be an old wasp nest above the starter):
Yellow wire spliced into blue wire, which goes to HEI distributor:
However, fuse block appears to have a pink wire already, instead of the expected white resistance wire:
slightly better angle (definitely pink wire):
Confused. Why am I seeing 9v at the yellow/blue splice with the engine running if the white resistance wire has already been replaced with a pink wire?
