You would want to remove the white plastic connector and install a T can be purchased at any parts store. Take a picture of where that line is sourced from. Where does the other end go??? I have a 2003 and the vacuum line was caped off just sitting there in open space. As I said the line should go to the driver's side below all the bracket that has the egr solenoid and Dpfe sensor. Should als be a red line with it that goes directley to the fuel pressure regulator on the same side of the engine.
