Please help! I just bought a 72 240Z I have a lot if work to do. The engine is seized from sitting for years and while I'm patiently waiting for the mystery oil to work I decided to try and figure out why the radio does not work. I removed it today and found it was completely disconnected. There is a antenna plug , a 3 pin connector and 2 loose wires ( red and blue ) please help? I think I found a factory connection for the 3 pin, although I am not sure where there other end of the fuse link is. Is it power or ground? And where are the loose red and blue wires? Key on power? And constant or ground? Thanks in advance
