well, I found a wiring diagram for the 2004 Xterra HERE . It'll help me with the install of the remote starter. I also found a remote starter that I think I want and THIS is it. I'm probably going to go around and ask some more questions from some wiring guys about what to do and such. But I'm thinking that with this wiring explanation, and the actual remote starter explaning what to do, that I think I can get this thing down. Any helpful replies, or even better any replies pertaning to this topic at all would be great
