Vacuum line for heater issues

Anyone have a pic of the correct vacuum for the blower motor door control?
I was moving stuff around, installed a new blower and trying to get wiring and vacuum lines cleaned up and organized, like an idiot I didn't remember the way to hook it all back up.
I'll try to describe it since I don't have access to a camera.
Ok, above the blower are 2 smaller lines, one connects to the bell/jar looking think that opens the selector door {I guess} and the other isn't landed on anything.
Now from the back of the motor is a line and on the firewall is a 3 way connector for lines. The one from the motor is hitting the 3 way, there are 2 other lines from the 3 way {on firewall} that are looping back together on ANOTHER 3 way T....
everything I select the door still stays in the default mode which is blowing from the top of dash {defrost}
Any help?
85 F-150 351W Had ac if that helps

You can purchase an original 1985 "FoMoCo Vacuum & Troubleshooting" Manual from helminc.com.

#0335521 / $14.00.

Helm has printed all of Ford's literature since the 1940's.

They have other Ford manuals available: Do it Yourself, Electrical, Transmission, Emissions, etc.
