Maf/iat?

[harnalien]

Ok, so i got my harness and started reading the instructions to find out if i'm missing any sensors and it looks like i'm missing some pretty important ones. it looks like i don't have the maf sensor or iat. i'm pretty sure the maf is the part that traditionally goes by the factory airbox (which i don't have). what i can't find is info on where the intake air temperature sensor (IAT) goes. man, it seems like it's always something that sets me back another few hundred bucks and stops me from being able to move forward . anyway, i posted a pic of what i have and was hoping someone could confirm some things. also, if someone could post a pic of their IAT and how it's mounted, that would be great. Can pic 1 be plugged (if so with what), or does something go there. I believe pic 2 is where the EGR went. Where does the other end of the hose on pic 3 go to? Thanks for any responses i can get.
