Does anyone know where the long grey tube goes? it located near the fire wall. When I put the car up on stands to look for more bad wires. (which I found one coming out of the fire wall exposed and dangling) I also found that that line was broke and cannot find the end of it. It looks as if it is going into the fire wall. Any help would be great I am so close to getting her running I can feel it ha ha
 
I believe it goes into the firewall in front of the passenger side. Mine are a mess too but that's where mine goes.
 
If it's a grey vacuum line it could be for the hvac vent control. Do you still have all the hvac vents blowing the air out the right place for the settings?
 
I have this problem on my cougar. although with the line supplied with vacuum, still no mojo with the vents. I believe it has come undone inside the car someplace. the problem is I have no idea where to look.

I did notice a diaphragm valve looking device on the driver side of the center stack, with a yellow and a red vac line on it. the connectors are corresponding clear red and yellow elbow connectors. sounds strange, I took a pic, I might have to host it unless someone knows what I'm talking about, and/or what it does, lol

but to clarify, yes, the little grey hard line that goes into the firewall is the vacuum supply for the HVAC controls...
