I'd say that the one that appears to be disconnected is not, it looks like there is a plug in it and that is pretty common.

Bottom (with green plug) is test port, port that goes right and splits goes to a vacuum tank and cruise control actuator (located in driver fender behind front wheel), last port that heads towards the firewall is to supply vacuum for controlling the hvac system underneath the center console. Have you tested and seen vacuum loss after turning off the car?

edit: forgot to mention in case, the top port goes to the break booster with black/blue check valve between for vacuum supply. I dont see the check valve in your pictures from those angles....

it is a plastic plug, I thought it may have been done by a PO. Thanks

All the other lines you described are connected as you said, the check valve is there, just couldnt get a good pic, the check valve is just above the 4 way junction that has the plug in question below it. Thanks, this Answers my question %110.

Thanks to all on the above!, I had another photo of another line in question, but having trouble getting that pic posted for some reason. It is on the pass side between the coolant reservior bottle and the washer fluid fill neck, its like a dash pot with a small screw in the top.

I'd look at this for the rest of your vacuum control system on how it should be:

Yep, thats the one, I dont know how you did that, Thank you.
My Hard drive in my main comp. took a crap while messing with these photos.
so while its in the geek shop, I have to revert to this 7yr old laptop for now.
Thanks again for all the help.
