Default AIR/EGR and PCV system Help!

Ok guys, I know it has been beat to death, and I already tried a search.

I dropped my engine/trans/x-member from the bottom and am pretty close to being ready to put it back in.

I have a few questions. Can someone show me the correct PCV routing for a 2000 year car?

I also have a catch can.

I have a tune that deletes the EGR, so I haven't been throwing any codes for that.
BUT.......

A few years ago when I installed my camshaft at a friends house, he told me that my EGR/AIR pump was the thing right next to the Belt tensioner when you are looking at the engine from the front, to the left, I removed it at that time.

I have since found that its not the AIR pump, and the pump is behind the Drivers side headlamp.

So what is this part located next to the tensioner?

So I removed the actual AIR pump and all of the hoses.
Also Have block off plates for the exhaust.

I'm trying to figure out what to do with the Valve on the rear of the intake. Just cap it off? Both the small ports and the large one? Do I leave all components of the AIR system that I am not using unplugged?

I also have an LS6 intake and am trying to figure out how I had the vapor line/ port hooked up. Or if it was even hooked up at all.

So I guess what I need is:

To know what that other pump deal is that is not the AIR pump
What my correct PCV routing is
What to do with the valve on the rear of the intake manifold
If my vapor vent tube needs to be hooked up

Thanks a lot, and just let me know if you need any pics.

The part you removed on the side of the engine was your air condition compressor and the valve on the intake can just be removed.If I remember correctly it just has one bolt that holds the bracket on the back of the head.just make sure to cap off the vacuum line that goes to it.the vapor valve doest really need to be hooked up but i would suggest that you do keep it hooked up.

A/C compressor is still on the car.

This part does not have a pulley on it, but it does have an electrical connector going to it.

The part in questions is clearly visible in the second to last pic on this write-up.

Traction control still works with this thing disconnected! It has some fairly large Vent type hoses that go to it.

OK, now that I actually looked at the pic I see I don't have that on my 2002, so I'm assuming it is the EGR valve.

I think you are correct. Thanks.
