Default AC Wiring Help

My air conditioning doesn't work. I've found some broken wires from and in the vicinity of the ac compressor, but its not obvious to me how they go together. If it makes a difference this is a MKIII system on a V12.

In this first picture there is a black wire on the right that comes from the back of the AC compressor. This has a female spade connector on it, to which a light green wire is also attached. The light green wire has black sheathing and is about 4" long before its broken off. There is a green/brown wire coming from under the front of the AC compressor. This runs along the V towards the back of the car. Its also broken off.


The second picture is a brown wire with black sheathing. It has a female connector at one end and is broken off at the other. There is also a plastic piece that looks like it holds two spade connectors.



The final picture is of three three pronged connectors dangling in the V. I think at least one of them goes to the cruise control, but I'm not sure if any of them are AC related or not.



I think something is missing from all of this. I've got a couple of boxes of random parts that came with the car, if I knew what I was looking for I might be able to find it, or replicate it.

I have a bunch of wiring running back along fuel rail you don't seem to have. I did move wiring from out of "death valley" but it was long time ago and memory is shot.
Your green/brown will most likely travel back to compressor relay and black should travel via pressure switch to ground. Not sure about your other green.
One of the multi plugs is cruise bellows (the one with a single exposed male pin) and the other runs back to connection at firewall. I think these two plugs were part of a recall dump valve install, previous to this the bellows plugged directly into the harness going back to firewall.

i think i have an excellent condition compressor loom in my spares somewhere if you need to obtain one ( now shown below) ,

this connections look like they have been well butchered and forcibly been pulled out of any connectors they were once housed in ,
