Ok I'm sure that this has been covered 100 times before, but I tried searching and came up with nothing. I've removed the rats nest on my S4 NA now where do i hook the fpr vacuum hose? Can I just connect it to the DC? Also what are you guys doing with the line running from the charcoal canister?

 

Run it to the bottom nipple of the three nipples on the front of the throttle body. I don't know what a dc is.

Or there's a unused nipple just below the secondary fuel rail.

Or the original source of vacuum for the FPR was on the left side of the dynamic chamber. A single nipple there near the air intake sensor. I stole a jpg off this site and pointed a red arrow to the area of the nipple. See jpg attached.
