Can someone tell me where does the top port on the aftercooler(cloest to tb) coneect to?

 

can someone please chime in

 

there are 4 total ports...

1 for the air pump hose, one for the bypass valve, and 2 for the hoses (in/out) that go to the heat exchanger in the bumper.

If you are talking about the hole on the top, that's the fill hole for the coolant...there should be a plug.

 

to the throttle body

 

im talking about on the right side of the aftercooler i only have three ports 2 for the heat exchanger so i guess the other is for the air pump hose correct?

 

most likely. If by the right side of the aftercooler you mean the driver's side-side of it, that is probably the air pump hose. If it's the passenger-side-side, it's probably the diverter valve hole. If this kit is meant for a MY06+, the AC may only have 3 holes.

I have the SOS aftercooler, but the connection is the same.

If that air pump hose slides right on, it's almost certainly the right hole...the location sounds right. The holes meant for fluid are related...blow in one and air comes out the other. If you blow into this one and air comes out of the TB side or the SC point, it's the right hole.

The diverter valve hole and the heat exchanger hoses are a good bit larger than the air pump hose.
