Help With Connections On Throttle Body

[t3intercooled]

Hey guys there are two barbed fittings on our throttle bodies. One on the underside of the throttle body behind the IAC sensor and one just under the 3prong throttle switch on the left side of the throttle body. Does anyone know what goes on these fittings? Any pics people can submit or any info people can give will be greatly appreciated.

on the heater pipe there is 2 niples on it. those have hoses that go to the barbs you are talking about. they are for coolant to go to the throttle body so it dont freeze in the winter. we all cap off the nipples in the heater pipe and leave the barbs alone.

So I can just leave the barbs on the throttle body open, or should I cap them off?
