Help Needed!

[foolonawheel]

I have a 2007 with the 4.7 V8. On top of the air pump on the passenger side of the engine is a vacuum chamber. The little chamber has two vacuum line ports. One has a line to go the the intake runner just above it.

My question is; where does the other vacuum port go?

I'm afraid that I may have to buy a factory manual to get a vacuum hose diagram for the engine!

THANKS!

Under the grey cover for the throttle body, pull that off and you will see it.
