S14/S15 Black Top with VCT Vac. Questions

[Stu240]

Good evening all,

This is the first real question of this sort I have asked.

I have searched and searched on this topic and can find plenty of info on the redtops but not so much on this blacktop.

I believe the way I have them hooked up will work, but I am looking for a little validation.

The two that are coming out of the bottom of the TB the left most one is capped, and I currently have the right most one run straight to FPR.

The two lower vac sources, I have the left most run to the cold pipe, and the right most run to the wastegate on the turbo.

I am not running, a charcoal canister, or a BOV or a Boost controler at the moment.

With that knowledge and the attached pictures can someone verify if this will work correctly? And if not what i need to change.

ALSO, there is a small vac source ( I assume it is a vac source ) coming out of the collector near the FPR, what is this for? Should I use that as my fpr source?

Any help would be great, this is my first project like this and I am so close.

Thanks,
Dan

The one on the side of the intake manifold circled in red needs to be used for your FPR. The one it is currently hooked up on is not a vac source, but a boost only source. The largest one underneath is your IACV air source. The other two are for whatever you'd like to use them for. Personally, the two throttle body ones can be used for the wastegate or anything that doesn't need vacuum. Only the three smaller ports(2 underneath, 1 on the side of the intake manifold) are true vacuum/boost sources.
