does any one know where to hook an after market boost gauge to my 2001 1.8t?

 

There is an vacuum line under the intake manifold where you can splice a "T" fitting into it, then run the vacuume hose for the boost gauge thru the fire wall to a place of your chosing, unfortunatly there isnt a place that is already plugged and ready for boost gauge, at least that i havent found. Hope this helps!
