LEt look up the diagram,
In the meantime,
What problem are you having?

There is other research in the ways of a tsb that may help you, if I know.

The IAt is part of the MAF. The tan wire is the wire that goes to the IAT portion.

Do you have a scanner or a DVOM?

No problems, I need to know which 2 wires r 4 the IAT sensor. I purchased a chip to increase my fuel mileage but it has to be hooked up to the IAT sensor lines in order to work. One wire is tan what color is the second wire. There all bunched up in the MAF sensor bundle.

I would contact the manufacturer of the chip, since it sounds like this is not necessarliy meant for one that has been incorporated with the MAF.
I can send you diagrams, but not sure if that will answer the question.
