    that would probably be your battery connection. connect it to a hot (charged) wire when the car is turned off and the key is turned off also.

    • get a cheap voltage meter anywhere but wal-mart , make sure its made in the u.s.a. and find a hot wire when the key is not in the ignition. this way you know the wire has power when the acc. switch is not turned on. this will keep your radios memory
