performance chip

I saw a performance chip for the rodeo that needs to be installed at the IAT sensor. Where the heck is that located on a 95 3.2v6

listen to this advice if your talking about the chips on ebay from $2.99
$12.99 there junk !
i got one that installs in the iat sensor and i noticed no increase in power at all!i installed it in a 1996 chevy cavalier 2.2l and now i have a 92 rodeo with 3.1 gm v6 wich my truck doesnt have a iat sensor if your does its located in the intake tube there will be a wire going through the tube wit a plug un plug and install the chip but i gaurntee you wont notice a dirrerence let me know if its the one of ebay
later man

yeah thats the chip!!!! i ended up not getting it becuase the guy told me that it was just a resistor and I dont even know if i have an IAT to install it properly. thanks for the advice
