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
