12V Constant = Constant power direct from battery. 12V Switched = Accessory power only when turned to the on/accessory position (example: car stereo only turns on when the car is running or in accessory position).

Putting a aftermarket radio in a 2000 sable?
Go to Circuit City and get a harness kit! You will need the harness kit that is available at Best Buy and other locations. However, my 2001 VW Cabrio did not have a switched +12V source (source that turns on or off with the ignition key). Without a switched +12V source the radio will remain on when the key is removed from the ignition if you have not manually turned the radio off and your battery will be drained. A switched +12V source is available from the rear defroster switch (black and yellow wire). Connect a wire from this switched +12V source to the red wire of the harness kit. You must also cut or remove the red wire from the socket of the wire harness kit because it will be connected to a non-switched +12V source of your car.
