... I don't see any way that it would make any more sense ... that port is
documented as a vent on the WX ... it doesn't need to be connected to
anything ... in fact if you started drawing a vacuum there you would be
working against the WG spring and actually causing the WG to open sooner.
Admittedly there isn't much of a vacuum on the back side of the airflow
sensor plate. Its been a while since I've looked at the engine in my car,
but I know that the line coming off the top of the igloo on the WX is
definitely connected elsewhere ...
