1999 Ford Escort Climate control

Electrical problem
1999 Ford Escort Two Wheel Drive Automatic

I recently had my radio upgraded to a aftermarket one. the radio works great and i'm getting better sound off the factory speakers then I did with the orginal radio. problem is now I'm having trobble with the climate controls. I do got a friend helping me who knows more about installing car radios then I do. he's determined it's a vacum line that's not installed properly, but says he hasn't had to install one on a ford and he thinks there might be a part missing. I found a picture of the mouting kit I used and added about excatly what problems I'm having with what parts. so what I need at minium is information or some good pictures on how to install the vacum line back into the controls, and what pices should be there.
and if you could offer any tips on getting the thermostat dial reconnected that would also be a plus.
I'd be willing to donate more if I get a really good detailed response.
