it's plugged into the fuel rail on the back side. If this is a SC coupe, find the PCV valve housing. Look just to the right of it and down beside the housing. You'll see the top of the regulator and it looks like a vacuuum diaphragm. There will be a vacuum line that runs from it to the vacuum block.
