Now you did it. You put the thought in my head. So I must work on it .
Hear is the new connector box I built for the rewire and the cover that goes over where the bulkhead connector was
What I did was removed the bulkhead connector, removed all the connectors/wires from the housings and drilled out each pass through with 3/16" bit. Installed the bulk head connector housing back in the car and pushed each wire through to the engine bay. No weak link connectors needed, no labeling, bulkhead looks stock instead of aftermarket.
