Right your pictures help some what
turbos plumbed, egrs plumbed, vac chambers plumbed and the one going through the firewall, they look correct.
The metal pipe is coming off the vac pump is that connected to anything at the other end
There should be two solenoids down under the air box, one is turbo, one is egr, they should have 3 vac pipes on each, now I think (I'll have to check) top solenoid (green plug) 1 pipe goes to turbo, 1 pipe vac pump and 1 pipe to egr solenoid, the Other solenoid (black plug) 1 pipe goes to egr, 1 pipe T'd to vac pipe from turbo vac to vac pump and the other obviously goes to turbo solenoid, without looking I think that correct but will look tomorrow, also there is a vac pipe that goes to the air filter box.
I will check and confirm or change as to what mine looks like. N
