1,2,3 - related to butterfly control system, how much they matter depends on how you hook it up, correct or not. for a really bad description that still needs updating, see my bigass post in the FAQ for butterfly control and misc. vacuumage.
1. vacuum line, T in after filter before turbo; this is used as air source for the butterflies. if not hooking up correctly but instead hooking them direct to manifold pressure, unnecessary.
2. probably had a boost gauge fitting.
3. not canister hoses, those go to the front of the intake mani / TB (you'll see a medium and small sized fitting, would match your stock canister lines, although they may not reach, connect same size to same size)
4. if it is you have that hanging way off the wrong way. should go to the back, and that doesn't look like the right peice..
5. that looks like one of the actuators, that may be for the stock bost control stuff, or possibly the butterfly control. depends on where it was on the motor, turbo side is boost control.
6. pcv valve i believe, goes to the intake side valvecover.
7. intake side goes to pcv valve, exhaust side goes to intake before turbo after filter (where 1 goes, same place).

Re: (daniel577h)
I think biosehnsucht covered it all, but you can save your self a headache and remove all these vaccum lines out and hook them directly to the intake.(including the metal vacuum lines which go between the intake port runners) less weight lol
The first picture is the vaccum line to your turbo, you will find a vaccum nipple on the turbo housing, T connect it to the vaccum hose on the waste gate acctuator and then hook it up to the vaccum metal line in picture # 1.Trace that metal line and on the other end, hook it to the vaccum line on the side of the intake, a bit bigger in size on the side of the intake.
T- connect your fpr (fuel pressure regulator) and the secondary throttle body regulator together and hook them to the small 90 degree bent nipple on the back of the intake(the fpr and the secondary throttle body are located on the back side of th engine between the back of the intake and the intake camshaft valve cover, they are shiny gold color with a nipple on each).
Picture number 4, that hose you need to run it right after the maf, it is for your cold air regulator, go to home depot and buy yourself a T connector from the plumming department with the same size and tap in right after the maf, if you have the hose that hooks onto the maf and goes to teh turbo, there should be a hole there already.
picture # 5, it suppose to go to the boost selanoid but you can illiminate it by hooking the turbo lines as I mentioned above.
picture # 6, you have to run a hose from there to the intake camshaft valve cover in picture # 7
also, in picture # 7, on the exhaust camshaft cover that 90 degree bent pipe, you need to T connect it to the right after the maf with the hose that you T - connected earlier from the cold air regulator ( so buy yourself two T - connectors from home depot)
Also, on the back of the intake, there should be a bigger 90 degree bent line which you should hook it up to your brake booster.
I hope you find this info helpfull.
Good luck,PULSAR GTRRafi

No! that metal line in the first pic is NOT to be directly connected to the compressor nipple! This would let more air bypass the throttle body.. on the other hand, thats one ghetto way to raise the idle if you have idle stability issues.
Just connect the compressor nipple straight to the wastegate.
If you aren't going to wire up the full ECU control of the variable butterflies then don't worry about that metal pipe there. In fact don't worry about any of them, just T the back of the intake plenum into the FPR and the butterflies.
