997 vacuum line routing needed
 Hi all, i'm looking to figure out the vacuum line routing for my 2008 997 3.8L. Im not clear how the system works. The "tuning/resonator" valve is governed by vacuum. I see there are solenoids and valves that are routed to the vacuum lines, but where does vacuum actually get drawn from? The secondary air pump doesn't seem to have any outputs. I got most the routing right, but I have two ends of vacuum lines that I'm not sure where to put. Any help would be appreciated.
