I just bought a 2000 Xterra and I love it. My issue is the radio. Previous owner cut the harness, so I found a radio and harness that was from an 04, wired everything up, and I can get the illumination to work (like when I turn on the lights), but not noise or display. Not sure if it's only grounded when it is screwed in, or if the harness is different from 04. Seems like all the wires were the same colors. I do have one brown striped wire hanging loose that is definitely a power wire, but not sure what it's to, seems to be a longer than all the rest. Any ideas?.... Nice to meet everyone.
