Vacuum Lines from Mechanical Controls.

[GS450-Junkie]

One of my vacuum lines from the mode control runs over to the passenger footwell under the knee pad. It attaches to a splice and then clips to the evaporator/blower assembly (I think). The diagram shows there is another piece of hose that continues to run upwards into the dash somewhere? Yet mine ends at the splice connector. It looks like it has and end piece on it where another hose is supposed to start. Just curious as to what it is supposed to really look like or do. See pics, hopefully it makes sense...

There's a thin, hard, black plastic tube/hose that runs from the top of that connector to the screen flap, also known as the air inlet assy, P/N 100475.

Pretty sure that the tube you want to connect to is part of that assembly.
The air inlet assy is item 1 in this diagram: http://store.delorean.com/c-362-7-1-2-air-ducting.aspx

Up high/forward above the blower motor. You don't need to find the assembly, just the hard thin plastic tube that's floating up there someplace....feel around for it. There's nothing else like that up there.
