Hey guys, I'm new to the 350z and I just purchased one Monday it came with stock stero not the bose version. I bought a head unit and two front door speakers. I Took the stock stero out connected all the wires for the new head unit and I went to connect the wires from inside where the old stero was. The only problem was that the head unit I got has the antenna and it came with 2 other connectors one is power and other is speaker wires. Their was a third white connector peice inside where the old stero was and I have no where to put that with the new head unit I got anyone no what it might be for? Or if it would still work without connecting it?
