It's marked P in 67 Barracuda sup. I'm sure it is in the FSM too.

I'd run a continuity check and make sure it doesn't connect to anything else!
You feel more than foolish if it connects to the parking lights (for some other application).
I beleive there is one circuit that grounds to the body in the switch. When the knob is rotated all the way it connects the dome light to ground.
So if its a ground, that's probably the one it should have continuity with when closed.
