under dash wiring question, please help

[Tuff Gong]

I want to start of by saying I know nothing about electrical. I'm was installing a new ac switch and radio when I noticed that there are some loose wires hanging out. I need help finding where they go. One is obvious, but I'm not sure if the double yellow wires go on top or bottom (where red arrow is). The other harness is a mystery to me. It may not matter too much because I have be running it as is with no issues.
