At the base of the actuator solenoids there is a metal vaccum line that points out toward the front of the car. It's the ONLY one that does this. I currently have no hose connected there and need to know where it connects to. Thanks

Looking at this I would guess it's the 6PI S.V. but i'm not sure

 

Does anyone have a picture of the S4 diagram or is it the same as the s5???

 

FSM 4A-5

 

I have seen this diagram, but the s5 one at https://www.rx7club.com/showthread.php?t=541260 is easier to read. Just wondering if anyone has taken a pic of the diagram under their hood of an S4.

 

That might help mazdaman. I'm not sure where a pic of the hood one is.
