I'm restoring a 72 240z that's been sitting for 10Yrs. I have power to the front running lights and head lights but no power to the rear tail lights. I have also gotten the brake lights and flashers to work. Car had been completely stripped down, painted and had new dash installed. I have also determined that the head/parking light switch is ok. Seems like I'm not getting juice where the dash harness and rear one connect.

Look to make sure the 6 wire body harness connector is connected to the dash harness. If it is, take it apart and inspect for corrosion and damaged connectors/wires.
