Upon closer inspection, I've noticed a broken nipple on the BPT. I believe the mystery hose routes to the egr solenoid control valve, and this broken nipple routes to the hard line that goes to the throttle body.

What really confuses me is that this hard line is pointing toward the front of the car, away from the BPT. The line will need to make a complete 180 under the manifold to connect, thus my hesitation and doubt to route it that way...
