So, the previous version of this diagrahm I have is labeled all wrong, so I was trying to get this filled out right, i'll start it with the easy ones I know and hopefully with everyone's input, it can be complete (and correct) shortly. Thanks.

3 is the EGR


The diagram is also inaccurate at some points.

Behind the rear head coolant flange there should be another hose coming from the rear to name one, and the DV to the IM line is missing. The IM line in red does not go to those solenoids (12,13) , etc.
