Hello,I finally got my Xterra,a white '04 V6 auto 2wd.The only way I could afford a late model Xterra was to buy a Katrina sunk/flood one.I am going to replace all of the electrical from a wrecked one.I need help,do I have to get another '04?, or are the '02 or '03's electrical components(computer,wiring harness,fuseboxes,window motors,HVAC switches,radio/CD etc.) the same? Thanks for ANY help!
