Radio Circuit in '69

The previous owner installed a new radio in my Coronet and didn't wire it correctly, so it constantly drains the battery. He hooked up the "ACC" lead to a hot terminal so it's got power all the time.

Is the radio circuit on the fuse block always hot or is it activated by turning the ignition to the on position?

Thanks!

Never mind. Answered my own question when I got home. The radio circuit is not hot unless the key is in the on position.
