bulk head wiring question

Don't be so hard on him guys. "Middle connector" implies he has 3 bulkhead connector, thus a 1966+ car and the "Demon" avatar narrows it down to a few years in the 1970's. I agree that "side marker lamps" is a good guess, since those "tee-ed" the "running lamp" wires, usually black w/ a stripe (grn, red, or yell) in the 1970's cars. You don't expect him to tell us that this connector was near the front fender do you or give a photo? That would make it too easy.
