Facelift Mystery connector for pipe

[Potterswheel]

Does any one know what should be connected to this outlet? it is on the righthand side of the engine just under the engine cover and between it and the airbox?

Nothing, Its blanked off.

Same here, it's blanked off if you poke an appropriate size object down the pipe.
