Sounds like this means that the only options for my radio are either always "hot" or Ignition II? Do you recommend that I link power to the clock? Will that mean that the antenna never retracts?
The antenna would retract when the radio was turned off. The battery would die when the radio was not turned off. Not sure how good a trade this is. The Becker Grand Prix radios will actually turn back on when the key is off if you poke the ON button again. I think somebody even said it was timed. They take both switched and unswitched power, of course. I've never looked at the electrical portion of the older ignition switch to see what is actually available there. -- Jim
