What are these plugs for?

I just checked again after installing my downpipes, and I think they're all EGR plugs. The two in the back that I couldn't figure out connect to another solenoid thing that attaches behind the TB on the K8 with hoses that go directly to the EGR. The Gray plug (3 prong) plugs into the EGR itself, and the black plug goes into a solenoid thingy that attaches to the stock airbox. There are tubes that go from this to the EGR as well. Since I don't want the EGR system, I think it's safe to say I don't need any of these 4 plugs - I am just confused because all the other posts only talk about 2 or 3 plugs for the EGR not 4.

If you don't hook up your EGR you'll always throw a code. You can disconnect it from the exhaust, just connect everytnig else. Make sure you plug your coolant lines as well.

Yeh I was thinking about doing that. Doesn't the chipped ECU fix the EGR code?
