99 B4 Legacy

OK lads looking for a bit of help here. I'm halfway through putting my engine back together and most of it is coming together quite well. I've ran into a problem though. Can anyone tell me what's meant to go in the space in the picture below? There's a vacuum line, one pipe coming off the inlet pipe, another coming out from under the inlet manifold and one coming off the top of it. Any help greatly appreciated.

Emissions/Purge solinoid

Would it look something like this? I think I have seen one lying around the shed somewhere. Would you know which pipe the top and bottom connect to?

That idea. Usually green plastic on B4.

Okay so if that's what the two smaller pipes are for, what goes onto the two pipe marked with red arrows?

Yes from memory middle pipe nearest plug to bottom (right arrow)

And bottom to left arrow. But would need double check.
