What are these two pieces? I think the one on the left is fabbed up for a SAAB intercooler, but the one on the right I have no clue.

This blue harness was disconnected under the dash. I started the car without it connected, and then I saw it was disconnected, so I reconnected it and it still started. What's it for?

Under the hood the intake stuff wasn't connected, so I put it back together the best I could. I can't seem to find where this intake hoes connects to. I thought underneath the plastic part that goes to the TB, but the hose isn't long enough.

This other hose doesn't seem to go anywhere either. It connects to the intake manifold below the brake booster line. I'm guessing it's for the blow off valve? If that's the case, what should I get to replace it with?

On to the dash, which is kinda a mess, what goes into this harness? My legacy L has a blank in this spot on the dash, so I don't know what I'm missing, if anything.

What plugs in here? Is it for the stock stereo?

Last one for now, here's the antenna cable, is this the subaru one? What's the other plug in part for?
