Im in the process of replacing the EGR assembly but after looking at several vacuum lines and noticed a few are broken this might be my problem, and I have no idea where these lines connect, does anyone one know or know where I can see a vacuum schematic?

Im including images:

This image is of the EGR solenoid you can see the nipple but I have no line and don't know what happened to it, does anyone know where I can trace this line to or from?



This image is showing a broken vacuum line, again I have no idea where this vacuum line connects at:

I've gotten my answer thought I'd post here just in case anyone else was having this problem

OK - you have that tree coming out of the intake plenum.
There are four hoses coming off that tree.

The Biggest Fattest one goes to the Power Brake Booster
The next Fattest One, goes to the Vacuum Service Supply Tee. (that's the thing with the rubber bulb that looks like an eye-dropper squeeze bulb sticking out of it) which connects the leak detection pump (mounted way under the van on the cradle).

That leaves the two thinner ones.
One of those goes down to the cruise control - its a long hose attached to the cruise vacuum reservoir (below the Master Brake Cylinder)
On my van, that hose follows the rout of the accelerator cables.

The other one, and I think you guessed it, goes to the EGR Valve Assembly. It runs from that tree on the Intake Plenum to that nipple on the EGR Valve Assembly.

FYI my check engine light was on took it to autozone pulled some codes related to EGR valve, found cracked vacuum line, replaced cracked vacuum link reset PCM, drove around a few days, passed emissions testing. Legal and on road again.
