1997 sw:.. aif? afi? ifa? help please

i just bought this thing online, basically its a resistor. it has 2 ends, and a little resistor like thing in the middle. the directions say to take off the (aif, afi, ifa.. cant remember) and insert it, then tape it down.. then not to re-plug in.. but basically, i have NO idea where this electrical plug is. it tells the ECM, EMC or whatever the air density if that helps.. can someone show me a diagram? thanks.

its actually the iat.. i just checked the instructions..

still looking for the plug tho..

Let me guess, those cheap "performance chips" from ebay right? Is it the power king by chance? Anyway the iat is in the air filter box. It's the only wire sticking out of it; just pull by the plug left and right till it comes out.

INSIDE the actual air filter box?.. i found this plug right outside of the box.. it says 2 d.e.l. or something like that.. it has 2 wires comming from it, like the instructions i got said would.. i was checking around, and it would of made sence that that is the iat because there was a "mini spark plug" looking thing sticking half way in, and half way out of the intake hole area... i thought that would be it.. so i put in the resistor, and didnt really notive a huge difference.. but i did smell gas.. so i thought it was doing its job.. maybe im wrong.. ill go check INSIDE the air filter box now

I'm sorry for not being more clear. I didn't mean totally inside the box, it sticks in the box but is basically outside like you said. I don't know if smelling gas is something to expect. It may throw a SES light sometimes. The reason it does this (most of the time anyway) is because a resistor fooling the computer (this is all it does and usually won't up the engine 20 horses as they claim) tends to make the air/fuel mixture too rich or too lean.
