If i remember right it is the vac line that changes your blend doors when you change from defrost to vent.

yea that is from my 02...it mounts on the back on the drivers side on the intake manifold...then the line runs along the back and connects to the intake on the rear passenger side...if you have a fast or ls6 intake there will be a port...

Are you refering to the Delco box? If yes, you can remove it and the short U shaped vacuum line. Both are for the air system.

Exactly what I did. Go for it. My hvac wasn't working for awhile so I took the intake completely off and found out a rodent ate through this vacuum
line. I was pissed
