So when I bought my Z I knew that it didn't come with a radio or speakers. The guy who had it before got it repoed. So now I'm stuck replaceing a lot of the interior and other various items. Anyway when I went to install some new speakers and head unit that I purchased my friend and I realized that the owner before me (god bless his soul) rewired the entire system so none of the wires are matching up. Is there anyway I can go about rewireing the system myself? Or if I take it to an Italian Nissan dealership they can rewire it for me? Any help will be appriciated.

Go pickup a testing light or get a 9volt battery and connect + and - wires on it until you here the noise from the speaker. Then process of elimination from there…Then drink a bottle of Chianti and go out with beautiful Italian girls!
