Previa D4D 2002 Vacuum Lines / Hoses / Problems

[DanielBearman 1]

Hi, I bought a 2002 previa D4D engine code 1CD-FTV. I've looked under the bonnet I've seen the vacuum lines look like madness. This engine is used in many cars so a lot if people here can help!

I need to know where all of the vacuums lines in the car are supposed to go to and where they come from. I really need help with this. OK so:

1. There is a screw in a vacuum line off the front passenger side of the engine (Image 2) - where is this supposed to go.?

2. A vacuum line seems to go in a circle. (Image 1). What about this one?

3. A few vacuum lines are missing.

One on the turbo.

One under the turbo intercooler pipe

One from an small orange (sensor?)

Two more from other parts all on turbo intercooler pipe.

Any ideas where they go?

Diagrams are helpful. But if anyone knows where the sensors are supposed to be plugged into that would be good.

I hope you can help,

Dan.
