I am not new to installing but could someone please send me a wiring diagram for a 2007-08 non-bose g35 sedan. I really dont want to go into this blind so even wire location help from the actual harness would be a big help. Im trying to ad a subwoofer and use an amp to power a component set to get some good midranges and highs. Thanks. I used the search function btw and everone is talking about the bose system so no help there.
