Dana. Your drawing repeats the same misinformation about power distribution.
IMO the more hacks in place, the more chances of execution problems. Problems with quality of the crimps, insulation support, wire support, fitting so there is no pinching are examples of challenges in good execution.
I've said my piece, which is pretty much the same as Rumblefish.
With a crackedback headlight harness, which is reversible with no damage, this seems like a no brainer.
That said I've posted how the factory wired the ammeter for the option 60/65 alts several times, and how I copied some of that at least twice. The only reason that might be neccessary here is damage to the factory terminals and connector cavity at the bulkhead from excessive overcharging. If this is an original 383 car even more the reason not to cut things up. I added 1/2 of the 60/65 amp wiring because I had cooked the bulkhead terminal (alkernator R6) wire and my car is a not a restoration. My car is a rehab that looks pretty original.
