The little electronic device at the juice can is the cruise dump servo. One of those nipples is a dead end. The top one with the little hooks had a little foam rubber filter over it. There are no lines hooked to that end. The other end is the one with the hose, and by your photo, I see it appears connected. Without this servo, the cruise won't work.
I have an AC bracket. I don't know if it's the one you need, or not. It's small enough to hold in my hand. Has 3 holes where it mounts to the engine, and one that would be a swivel, as it has a bolt passing through it. It's solid steel. The other is aluminum, has 3 holes to mount to the engine and a widely spaced area where the compressor fits. It's about 10-12 inches long. $10 for the steel one, $20 for the aluminum.
The climate control switch on the dash is the common no-work cause. The trace he's talking about is part of the printed circuit. I have 2 on hand. One without cable and one with. You would only need the one without cable. $15
