The radio is on the same 15A fuse as the 12V accessory for some reason. I
don't want the radio on all the time though. Any idea where the radio and
accessory wires are joined ? in line somewhere or at the fusebox ?

I can't answer your question without a wiring diagram, but you can get taps
for blade-type fuses and insulated crimp connectors for the taps at auto
parts stores. Tap the fused side (the side that gets disconnected when the
fuse is pulled or blown) of a fuse that is always hot, like the dome light;
connect a female insulated blade-type crimp connector to a wire and connect
the wire to the accessory socket. Look at the back of the socket for a
connector that will fit, and unplug the factory connector. This way, you do
not disturb the factory wire harness and can easily return it to factory
condition when you sell the car.
