Okay. Heres the run down.
As greg stated, make sure you have a line going from the turbo outlet pipe nipple (boost source) to your wastegate diaphragm. a MBC (manual boost controller) or any other style of boost controller will connect to this line. Then you have to have one line going from the intake manifold to the BOV. (DO NOT use a source from any of the throttle body lines to use for the BOV vac source. it needs to come from the larger port in the intake. I found this out when one time I used the output on the throttle body on a BOV and I got constant BOV chatter/surge from the turbo. the port on the TB just doesn't provide enough volume to keep up with aftermarket (or stock) BOV's. Just cap off all the ports on the throttle body and put a egr block off plate if u wanna get real fancy lol. or get a vac diagram and hook back everything like stock LOL. ahahaha
As for the intake pipe you showed... there is the obvious large port for the BOV dump return. On the back side there are two medium sized ports. One goes to the charcoal canister (under battery tray). (used to let the engine burn off stored up fuel vapours from the fuel tank) This can be blocked off tho if you have also blocked off the throttle body lines, the valve wont work normally anyways. just make sure to leave it vented somehow, cuz it can cause issues with the fuel tank not venting properly. The other line right near it on the intake pipe goes to the side breather port on the side of the valve cover. this allows fresh, filtered air to enter the crackcase at idle, and also offers a little crankcase suction as well under boost. (can help with excessive crank case pressure under high boost. A lot of people end up running that line to a catch can system to help catch any oil vapours and try and avoid getting them into the intake piping/intercooler/engine. There is also the small formed hose that runs from the LARGE vac port on the front of the intake manifold to the PCV valve on the valve cover. This helps pull a small amount of vacuum on the crankcase at idle, and the one way valve in the pcv valve should also close under boost conditions.
on the MAF housing, near where the intake pipe connects you will also see a small port for a small vac line. This connects to the stock boost control solenoid, and can usually be blocked off as well.
Then you will also need one vac line that runs from the drivers side area of the intake manifold to the FPR (fuel pressure regulator). This is used to increase fuel pressure as boost rises, and also under vacuum decreases fuel pressure at idle a little bit. Stock this line runs over to the firewall to a solenoid, but most people just bypass this as well. The solenoid is there to cut vacuum to the FPR under hot starts to prevent a momentary lean condition, effecting emissions, and sometimes drivabilty for a short second.
