    A/C control vacuum diagram?

    Hello All, This is my first post.I have used info from here to repair a few caddies for friends. Great info and people here.
    I have a 84 Coupe Deville 4.1, I am helping a friend out with, someone has been under the dash to try and make the air flow from the dash vents. I found that they disconnected the Map sensor and sliced it to a black hose with orange stripe.
    I am trying to get things back together where I can properly troubleshoot his real problem. Can anyone tell me where this Blk/org hose connects from the controller or where I may find a diagram.

    Thanks Bill

    I believe the orange one goes to the recirculation door.
