I have just bought a Meos MC702B multimedia system (rubbish sounding make I know, but its supposed to do everything) for my 06 350z. I bought a PC2-72-4 stereo harness on the advice of Halfords. It looks to be the correct one when doing some google searching, however the iso harness has 2 connectors, but when I removed my centre console, I saw that there were 3 connectors, plus the antenna lead. When I connect the adaptors that fit, I see that the black earth wire from my Meos does not have a connection with the vehicles leads. I am also having a problem trying to install/connect my Meos to the cars stereo bracket.
Has anybody installed one of these yet, or could help with the above? I am about to pull out what little hair I have.
