key goes in, radio powers up

Backally,
If you review the link to the wiring diagram that WJAJR posted you will see that it shows a key in switch buzzer as well as a headlight reminder (Lower right corner diag. 2). My concern with that is the key in switch buzzer should only work if the door is open that is why I asked. Did you install a factory radio or an aftermarket radio? I will continue to think about this in the mean time hope the head cold gets better.
