Check the schematic diagram for the emissions system in your Haynes manual to see what hoses go where and what the different components are called. The EGR solenoid valve is between the firewall and the rear cylinder bank, IIRC. (Follow the little green hose from the EGR back.) The DPFE is either on the back side of upper intake manifold, or is down in the maze of tubing below the EGR valve. I'll look more closely tonight when I get home.
