ok previous owner swapped in a jdm 7m and there is lots of wierd wirring that was done to it and things that don't make sense. Anyways i noticed that one of the green niples by the coolant sensor has no vaccum line on it. IT has 2 green like nipples with one being sorta broken off. The car has always ran fine without it but does anyone have a pic of where the vaccum line goes to or what the puprpose of it is???
