95 aerostar 3.0 vacuum housing and diagram

This has drove me nuts. Im trying to figure out if all my vacuum hoses are hooked up to my vacuum tree. I have 2 nipples on the tree with no hoses and I had to use caps, not sure if a cap was on there before and finally fell off or if there is a hose that went there. I can never find a good photo to show where the hoses go from the main vacuum tree which is right next to the distributed. Does anyone have photos, a website, diagram or any info on this??

The hoses on a 3.0L vacuum tree lead to the:

1) Brake Booster (located on the drivers side)
2) PCV valve (located at the rear of the drivers side valve cover)
3) Fuel Pressure Regulator
4) Vacuum Reservoir/Climate Controls (a very narrow white plastic hose similar to that used on the window washer system). The hose leads into a rubber adapter that attaches to one of the nipples on the vacuum tree.
5) Vacuum Modulator (older model Aerostars only) - Located on the transmission

Cap off any unused hose connections on the vacuum tree. Most auto parts stores sell a multipack with various size plugs. Insure that every hose and plug is securely connected. A backfire can easily cause any of the hoses or caps to blow right off of the vacuum tree. Use small hose clamps on them where necessary.

I think there might be a few more vacuum connections:
EGR (if you have one, my '95 4.0 didn't but my '97 3.0 does)
cruise control
evap system

The EVTM doesn't show all the vacuum connections, which is disappointing. There might be something else that's missing.

they come from the factory with a vacuum line diagram on the frame above the radiator or on the underside of the hood.
