I'm putting my intake back on, and can't for the life of me figure out where this vacume hose goes. The one right in the center of the pic. We're looking between the pass. fender and the pass valve cover. Can anyone help me out? thanks!

 

try the back of the intake next to the map sensor .next to the vac.line going to your brake booster hose.

 

That would be the hose that goes from the back of the intake to the brake booster on the driver's side back of the engine bay.
