mini fridge to mothership

Hey guys, here's some pics of the wiring on the back of the mini fridge. I know I have a lot of work to do as far as fans and stuff but I'm not sure which wires are what. If you can help me figure out what is what I can atleast start to plan out the build a little better

Is the green wire the ground?

bumpity.. still no love from any electricians out there??
