Default 1981 CC vaccum scheme

Hi guys
my Cruise control stoped working and I need to know where are the hoses and wires connected to.
Does anybody has such a diagram?
It's a 1981 VAN G20 with a 5.0 l enigne

Thanx

CC? Climate control? If so. Is the compressor working? Do you have air coming from different vents as you change the selection?
Kinda need more info.

Oh. Ok. There is a vaccum diaphram next to the carb that links to the throttle cable. Is that working?

I don't know, have to check it.
But I think it will be an electrical problem, after I fixed some wire problems around the fuse box, it stoped working.
I've checked the switch on the pic. The valve works, where these two wires are connected to? what are they for?
Where can I find the "cruise control unit"? Is there one, I think so.
The vaccum hoses are looking new, I can't hear something if the engine is running. (no leak)
If I push the "Set" button I can hear a klick in the speaker, some eclectical noise.
BTW: Why do I have to release this button slowly, as written in the manual?

thx
