A.E will not find the VIN on your truck. that feature is for the newer trucks. you have to enter the truck and engine info manually. you also need to activate the ford bundle with A.E. before it will work. the blue paper that came in the box with the paperwork explains how to activate it.
ands try to be patient, cause it takes time to figure out. i have had mine for about a year now, and am still learning things about A.E. and how to use it.
