#4 is for the MAP and AFPR. Only those 2 items should be connected here.
#3 is for.......damn, I can't remember

OK, I think I remembered. #3 is for the charcoal canister?

Wha'd I win?

Ah. Rear source T's off to FPR and MAP. Front source runs toward the back under the throttle body. EGR solenoid, cruise, and vacuum ball lines branch off before it goes to the HVAC controls. The vac source on the bottom of the TB goes to the charcoal canister.

Thank Ian's pictures, not me. =)
