Well guys I am pitting on the new Accutane TB and noticed none of the vacuum lines are plugged in. It's had the get deleted. Only two still have ends the other have been cut. Where do they go or do I even need them?
They are for your EGR and smog pump solenoids (TAB and TAD). If all that stuff is eliminated then you don't need them. I would recommend disconnecting the feed line from the vacuum tree on the back of the intake and capping it off so you don't have a vacuum leak.
