2003 Mach 1 Wiring

New to the forum. Picked up a 03 Mach 1 and while cleaning I noticed this. Does anyone know what this connection is for? Can’t find a connection point for it.

Hard to see on the angle but you should have a heated PCV valve and it goes there. Guessing someone put a normal one in it's place and left that unplugged.
