I’ve just finished swapping in a red top sr and get everything hooked up, except the vacuum lines. i know on the throttle body there are two places on top where the vaccum lines can go and it looks like there is one on the bottom. i have an hks bov and i ran the line off the back of it to the wastegate. there is also a vacuum line coming from what looks like part of the fuel rail. now im just wondering what lines go where? thanks for any help guys.

The line coming from near the fuel rail is suppose to go to the PCV valve.

the vacuum line diagram is perfect but im using an hks ssqv bov and no cannister. i’ve read things that say to run the bov straight to the wastegate with no “T” and also to run straight from the TB,im j/w if i should run it from the throttle body and bov with a “T” to the wastegate. thanks guys

How are you gonna run your BOV straight to the wastegate? Then neither are getting a vac/boost source. You _need_ the T.

Your proposed setup is acceptable.
