1967 Barracuda center console wiring

If I'm understanding you correctly, the plug in for reverse lights is at the shifter itself. 2 wires, white and violet.
So for the abodies with automatic center consoles there are two wire harnesses. One intermediate harness that plugs into the reverse light circuit and the headlight circuit. This runs from the steering column area over to the passenger side kick panel where it then connects to the harness that runs under the carpet to the center console and connects to the reverse light switch and the gear shift select light. I have that console harness but am lacking the intermediate harness AND I can’t find the factory pig tail connection for the reverse light power near the bulk head.
