Vacuum Help (Again)...
 

Where does this hook up?

That goes to the 3" intake tube that comes off the AFM and leads on up to the throttle body. It provides a 'filtered' air intake source, so dirt does not enter the engine.

agreed, bottom fitting on the accordian hose.

Thanx http://www.toyota-supra.info/forums/...ons/icon14.gif, I should've poked around a little because I found it without checking back to the thread. I always like to be cautious though.

I had my intake tubing off several times over the past couple of years, and I sometimes forgot to put that vacuun hose back on. I would remember soon after while driving, and have to pull over to plug it in. Its easy to forget when its black, like most of the stuff under the hood.

Those colored vacuum lines are the way to go.
