I have a 2007 f150 5.4L and bought a magnum performance chip and I`m not to sure which wires i splice it into. It says it goes on the intake air temperture sensor which has 2 wires but ours has the wires from the MAF sensor too. How do i find out which 2 wires out of the 5 are for the IAT sensor? Thanks in advane for any help
