Start here: https://www.nicoclub.com/service-man...F2003%2Fpg.pdf
at the bottom of that window is "Click here to download a copy". That pdf is the "Power and Ground" service manual for the 2003 g35 sedan and it includes illustrations of the wiring harnesses. So based on where your mystery plugs are (??) you should be able to track down and decode what they are for. It takes some digging through these manuals, but the info is in there. Meanwhile, here are the wire color codes to help your search.
