That's not a white bulkhead connector -- They don't use the top wire (pin #44), and the other wire colors are wrong...
The "mystery red connector"- Early models had two red connectors (Auto v/s Manual trans. The extra was clipped & taped off.) IIRC, the one with two Green and one White wire that loops right back into the connector is for Manuals. The one for an Auto uses every terminal (9).
