i did an IAT mod on my old ranger, and i am wondering where the air temp wires are on the zetec engine so i can mod it. for those who dont know what i wanna do - put a 5.6kohm resistor in series with one of the 2 wires to fix the air fuel mixture for racing time.

the IAT is in MAF as Llama pointed out. however it is a seperate circuit. the IAT sensor is a thermistor. with one send wire and one return. It shouldn't matter which wire you use to tap the resistor into.
