S5 turbo on S4 motor, where does this go....
Theres a nipple on the cold side of the s5 turbo that wasnt on my s4. Where does it need to go? It T's off of the little vacuum pipe the runs around the front of the cold side.
Cap it off someway. That was used on the series five's Duty Solenoid Valve. It controled the boost pressure. Your series four cannot perform that function. You have to cap off that pipe opening.
