Continuos to various points within...
The yellow ones generally are tied to the vacuum reservoirs (rear reservoir is for locks, fender mounted reservoir is for acc, I think) and the others supply direct vacuum to the acc and other accessories i.e. ignition switch engine kill module, on a 123CD there are blue lines also that are for the seatback locks I think.
For clarification on the thingy next to the alda it is the vacuum bleed valve that controls vacuum to the tranny for shifting purposes. This valve allows air into the system when you are at full throttle reducing your vacuum to the tranny and hardening the shifts. This is so during hard acceleration you get a good hard shift and no flaring.
I have seen other cars with the green valve (may be a damper after all) on them at the point of the connection to the top of the bleed valve. This would indicate then that the valve should allow air INTO the main system but not out the bleed valve when it is open. I have never really gotten this as if the bleed valve fails it will allow air into the system and nover out because of the vacuum...
I have been running without it for some time on my car and theoretically I don't know that you need it unless it controls the amount of air allowed into the system to reduce the vacuum (hence damper).
The black line that comes off the side of the bleed valve goes into the passdenger compartment which is where the bleed valve gets it's air when it opens. Why? I have no idea, but that's what it does.
Hope this all helps...
