Yep. you're right. I checked on that. the 5.0 explorer was from 1999 to 2001 and they have a new Scanning tool out now that reads the VIN number that is burned into the ECU. If it doesn't match it's consider track use only. Plus you were indeed right about the wiring. 2002 was when alot of the new emissions changes were enforced namely the EGR Valve became mandatory, catalytic converters became more advanced and swap laws started popping up all over the country. here in VA,CA, NY and a few other states has to be the same year or newer.
