WHICH WIRES ON THE MAF ARE FOR THE IAT

I am putting on a resistor chip, to see if it really improves my mileage, but I cant seem to find anyone who knows either where the IAT is or which of the 4 wires on the MAf are for the IAT

Do you
have the same problem?

It appears it doesn't have one. You were just wasting your money anyway.

No, it does not. I just looked at the PCM wiring and it does not have an IAT input.

A minute ago it was mileage that you wanted to improve. Now it's power. They are completely opposite goals and if you get one, you lose the other. You have a computer controlled car. Other than keeping it well tuned, keeping the tires inflated properly and changing your driving habits, your only other option is a different vehicle but first decide whether it's power or fuel mileage that you are after.

You want a little power try this -use a 10K's ohms resistor on the coolant temperature sensor harness-There's a lot of ways to improve power but do you have the funding for it?

Sorry to confuse you, the reason I said that was because this "chip" was supposed to do both at the same time. I have already email the company for a return and refund, any car with AWD gets only moderate mileage. So im fine with getting a little worse mileage, but would like to get a little more power for take off.
