RB25DET plug identification please.

i have a few plugs that i dont know where they go. but i only got a couple pics before my phone died. if you guys could help me identify these, i would be much appreciated. also i have a question for the wiring guys. the guy that did my harness has moved and i cant get a hold of him. he didnt extend my maf because we didnt know which route i would go with the turbo and intake and stuff so we didnt know the placement of the maf. so that means i have to extend the wires on the maf. i know how to solder and what not. im just not sure if i can go and solder the extra length or is there anything special i have to keep in mind?

that kind of looks like the plug for a sensor under the intake manifold, is it connected with the knock sensor harness

i cant remember which one is connected with the knock sensor harness but yes one of them is (i think the blue one is connected with the knock sensor plugs)

No and No.

The purple one goes to the IAC valve or FICV on the intake manifold. Can't remember which color goes to which one (other is brown), but the male part of the plug is color matched to dummy-proof the harness install. Honestly, it is impossible to connect anything improperly on the engine harness.

The blue plug goes to the air regulator underneath the manifold. You can barely see the male part on the regulator housing through the runners, but it's there. Time to try your hand at being a contortionist.

thanks for identifying those. i know its impossible to plug things in wrong. problem is i have 4 or so plugs by my fuse box on the passenger side that do not have mates. i have no idea what goes to them.
