I'm looking for the location of the IAT plug. Ibought a "wonder Chip" all it is is a risistor that bypasses the IAT I'll try it anyway suppose to increase fuel milage and power??

do not put that POS chip in for the IAT , it will jack like 30 degrees timing in your truck which will make it ping like crazy , if you want to add power , get an aftermarket tuner for it , Sniper Special Forces will work on that truck , and then you can add timing and change the fuel curves for more power , without messing something up , and by the way if its its got 6 wires going to the mass air meter then the IAT is intergrated into the MAF ....
