twin scroll vaccum? rats nest

I need to know where that metal tube that comes from the turbo goes? I also removed the rats nest and is there a solonoid .. like the boost solonoid? I also capped the vaccum line between the oil injectors on the lower intake manifold and the bottom nipple on the back of throttle body.

if your twin scroll is still intact you will need the solonoid that has a green connector plugged into it. That is the twin scrool solonoid. you can plug the vac line comming from the turbo to the solinoid and then from the solonoid to any vac source. Make sure you have a check valve.

I also capped the vaccum line between the oil injectors on the lower intake manifold and the bottom nipple on the back of throttle body. Is this okay. In the FSM .. the nipple between the oil injector on the LIM is connected to the top off the nipple on the back of the throttle body.. Is it okay that I capped this?? I would really hate to take off the upper intake manifold again. Please let me know. Thanks again!

I have a jspec so its not the same but from what I remember the oil injection line was a bigger nipple and the smaller nipple is a vac line and you can just cap that.

I dont have oil injection. I removed the metering oil pump and the lines. gonna run pre-mix. i capped the bigger one because i dont use the vaccum spider.. but i'm just concerned of the vaccum line stated above.. i don't think it should make a difference. but i just want to be sure.
