I'm not 100% sure on the exact location, but it is under the hood. It will be near the intake manifold. Hopefully someone will chime in with an exact location. A quick way to check would be to follow the EVAP line from the driver side of the firewall up to the valve.
Like in the other thread, the one you need is UNDER THE HOOD, and fed directly by the manifold with a short length of hose...maybe 3 inches long or so. On the back of the manifold next to the firewall. If you need a picture, let me know and I'll post something up for you.
That electrical connector on the bottom side of the PCSV and the passenger side hose are proving nigh impossible to remove! Any hints for how to get them disconnected? Yes, I have the little metal thingies moved up the hose....
edit: Never mind, it just took a bit of brute force and I had to pry with a screwdriver.
