Getting car back together after 6 years in pieces - pretty close, but I'm trying to figure out what exactly these are or go to. I can't sleep at night until I know, haven't been very successful searching some of them. Any help or input appreciated

The first is a multi plug i found tucked back near the blower motor. Assuming something to do with a/c, which I completely deleted.

Second is a two wire plug, having a thicker gauge blue wire. I may have read it was an a/c diagnostic port but that was in a 1g thread so not sure.

Third I believe is the wire for my rear hatch defroster, but it was taped with my stock amp wire and both had been cut. I want to know where this attaches to so I could possibly rewire it.

Fourth looks to have some sort of nozzle and may be a drain or have to do with the wiper fluid motor? No idea, I just noticed it was unhooked

Fifth is a ground near the ecu that I want to know where to correctly reconnect

Sixth is a male plug with a ground attached that runs near the ebrake, it was tucked up under the cd player area. Mainly worried about the ground and where it attaches.

Seventh is a bonus. What the hell is that? Comes off my cd player harness. Just want to know what it does and where i should mount it idk

Number 2 is the blower motor power.

For #3, since you believe it to be the rear defroster, which side is that wire on? I have messed with my rear defrost wires a bit and can say that the driver side of the system connects from the window to the top of the hatch near the hinge and is a black wire. On the passenger side, it is a short wire that connects from the glass to a bolt where it grounds a few inches away. Also a black wire.

#4 is the feed hose for your window washer fluid from the trunk reservoir.

#7 is an aftermarket ground for whatever someone has or had hooked up at one point. You could probably eliminate it if you have nothing you think needs it, or better yet, trace where it goes and take the whole wire out.

#5 is definitely a stock ground and should be bolter somewhere very close to where it is ran. My guess would be the metal right beside it or below the carpet right there.
