In the fsm there is a good diagram of the vacuum system. Just need to follow each line to their end.

Or if you can get away with it do an egr/vac delete which will rid you of most all of that.

I'll give it a shot:

What goes on A This has an S shaped hose to the intake bubble
What goes on B Goes to the firewall hard line for the brake booster
What goes on C This is aftermarket. Most people hook up a boost gauge here
What does hose E conect to Goes to purge solenoid. Connect to I
What does hose F conect to Goes to EGR solenoid
What does hose G conect to Should go to a tee in the Yellow color vac line (EGR valve)
What goes on H Goes to tee in the Green vac line (EGR valve)
What goes on I This is the purge solenoid. Connect hose E here.
What goes on J This is the factory boost solenoid. Should go to the blue bleeder hose in your setup

Dave/TT4ME provided them to me a few days ago; I had seen them several times before I needed them but not thought to save them.

Hats off to him, I say. :D
