need help with intake air temp sensor

[mvb1212]

I bought a mod chip after i saw what it did to my buddy's 3000 GT and his is 300, it requires it t be hooked up to the intake air temp sensor
(IAT). does anyone know where that it? cause i thought for sure it was the on right on the air intake but now that i look at it i dont think that plug or sensor does anything?

what model celica do u have? the chip aint gonna do much. i put one on my celica and the first time it made it slower so i kept putting it on and off and finally i got a small result(like .2 seconds off my 0-60 time. relly all u got to do is buy a cheap ass resistor , it is all those chips are anyways. if ur celica is a 90-93 it should beon the air box right beside where the hose connects to the box.

those chips dont do anything but decrease ur gas mieleage, therse no way to ovveride the iat sensor because of posotive manifold pressure
