You mean the parking lights?
Can't help on that. My 67 always has had the parking lights on with the headlights. I'd have to look if that's a Barracuda only feature in 1967.
The difference is Barracudas have L6 and L7 wired to R terminal.
Darts and Valiants have L6 wire to P terminal, which Dana's continuity test shows as disconnected with headlights on position.
