vac line on 420 sel

[SKEE bo]

Ok I was looking under my hoood {420SEL 1989} the front pass side right behind the head light I found 2 vac lines jus laying there with no connection,one hose is white with a blue stripe & the other one is white with a blue & a red or burgungy stripe, I also see a little connector that has 2 inlets, the lines look like they came off the connector(but I dont know)
could any one tell me what these lines are for and if they goto the connector I found? Does this have anything to do with the tranny? im getting late shifts also my door locks move slow is that normal ?

One more thing where is the ICV located and is there a way to get tranny fluid out without draining the tranny, the trans has too much fluid in it(when i checked the level numorus times its always gives me a high reading above the two marks on the dip stick)
