The wiring diagrams you sent me are not the ones I was looking for. Specifically the 2nd drawing is DDEC 2.

Note there is not a line item EGR Valve. The 1st is a wiring diagram dash to sensors, or sensors to dash lights.

However you want to look at it. Unless you can point out the actual location of the VPODS to ECM.
