96 drivers side intake vacuum lines
 

Does it matter which of the two intake vacuum ports go to the opti and the egr. These may have been switched when I did the intake gasket. The pic on my car showing the routing looks like the opti goes to the farthest back and the more forward is the egr. Correct?

No, just make sure you are pulling vacuum through the opti. So intake manifold, opti, then air box.
