vacuum line identification help pls

[Tx_Atty]

Im putting in my version of the AC mod with the vacuum solenoid. I have read all the posts here and the other place and my lines dont look like the ones described.

What I want to identify - a line that draws a vacuum for both vent and AC. Attached are some pics I have taken under the dash. I see a vac thing right under the data port that I watched operate under vent and AC but cant see a line to splice. There is a blue line to it but not enough room to work.

Going toward the passenger side there is a pair of lines, black and white, that go to a triagular thing with 3 "ports" on it - they take up two and one is empty. What is that and can I put my line there?

Also - the other end of the white and black lines meet up over the trans hump and go to a larger plug with other lines - yellow, red, blue. Also pictured.

I only need to "t" into one line that will create vacuum in vent AND A/C. Any input would help. See pics.

Thanks!

Tx_Atty-

Did you look at rexaford's webshots montage? he has schematic there. since you are OBS, i dunno if its the same.

you might want to look at steve baz' pages- he is OBS for sure and his suggestion is white.

I had read Baz's but white is only for Max setting or Off. I want anything left of off. However, your link to rexaford's shows a chart and I think the black line will be what I need. It is vaccum all the time and my solenoid is what will control the water valve so that might just be perfect. At least the color chart lists the same colors I have. Cant be too much different. I hope.

Thanks for the help!

(if Im wrong, noone hesitate to set me straight!)

I got the water valve installed and vac line run through the firewall, got the dash switch (lighted) mounted but not powered. I ran out of time before having to be somewhere tonight. Tomorrow I will mount and wire the solenoid and should be ready to test it out. I will make a write up if anyone wants to do the mod this way. Even if it is already installed, my version can still be set up. I need to take some pics.
