from heavythrottle.com:
"The vacuum lines are simple: 3 lines start at the throttle body. The bottom one goes to the canister, block it off unless you are using the canister. The larger one on top runs to the bypass valve (BOV). The smaller top line tees to the fuel pressure regulator, and runs across the front of the engine to your boost gauge and/or the boost pressure port on your boost controller.
The wastegate gets its signal from the nipple on the intercooler piping. The Apexi boost controller stepping motors go in between the IC piping and the wastegate actuator."
i did mine a little differen't, let me know if this is ok:
i ran the larger line straight to the wastegate (because i don't have a boost controller yet) and the smaller one to the BOV and fuel pressure regulator. i did this because they seem to fit better this way, and it looks great
. do the large and small ports on the throttle body get the same pressure and vacuum signals?
by the way i did block off the small port on the bottom of the throttle body with a nail and clamp? is there a better solution to this (like a cap of some sort)?
