Default "WTF is this thing?" Part 3...

Got my wiring harness back today. I have a couple of questions about a few plugs on the harness:

#1:

Where does that go?

#2:

What goes in this slot?

#3:

What is this and what do I do with it?

#4:

Where does this go?

#5:

x2

#6:

Not sure if this is an LS1 piece. It may plug into my mazda chassis, but I haven't moved its body harness over yet

#7:

These two harness plugs are on a large separate thing of wire. I believe they connect to the transmission.

#8:

What connects to that?

#9:


Where do these two plugs go?

#10:

This appears to be a ground strap. It comes out of the harness close to the alternator. Do I just connect it to the block?

#11:

Is this correct? The piece marked "ground" is another thing that looks like a ground strap, like #10.

#12:

Another possible ground strap. Just connect this somewhere on the block as well?

1 looks like egr on the passenger side.
the other picture with 2 in it looks like the lid and the TB sensors.

#5 is (according to torquecentral) something that connects to the ignition cylinder.

Not sure if it connects to the ignition on or the starter circuit though.

#3 may be AC, however.

Can't find the plug for the MAP sensor. Could it be #1?

Could #3 connect into that hole right above the "ground" text in 11?

The hole above the "ground" text in #11 is a block plug for the coolant passage (i think).

#3 screws into the ac line that runs between your evaporator and condenser.
