From there it continues to behind the intake manifold into a T (arrow). Can someone tell me where the lines go from here and what they do?

Thanks!

That supposed to go to a vacuum nipple on the 3B intake, under your ISV.

Thanks, but I need to know where this line originally went to on the CQ.

Not 100% positive, but I think that it's for the climate control system. (flaps, etc)

yeah, one end of it operates the flaps. I hooked the other end up to the IM.
