Hi again, this board has been so much help to a newbe, I first want to thank anyone who has tried to help me in the past and made my life a lot easier. On the right side of my cylinder head towards the front I have what looks like a thermo vacuum switch (valve?) one line is connected to what i would call a canister located to the right of the AC compressor. The other connection is not hooked up and for the life of me I can't locate a line not hooked up. Where does it go?
