There is a plug with four wires that connects to the MAF sensor, which two of these four wires connects to the IAT?

Thanks!

 

LOL... I asked the exact same question before! Everyone here will just tell you that MAF based car dont have the IAT sensor, and only those MAP based car have it. In addition, they will also ask you "YOU DIDNT BUY THE CHIP FROM EBAY, DONT YOU???". I had bought the "G-Box" thing before but cannot install it too since I got the impreza'99 (MAF based), but now I had the Torque Chip 2 installed in my car and I was very satisfied with the torque/hp gains! Hope this help.
