My 1982 Westy has no AC position on the ignition switch.  The stereo I had
in there did not switch off when you turned the key off, which I kind of
liked because it made it easier to listen to the stereo when camping around
outside the vehicle with doors open.

When CAR-TOYS installed my new stereo recently, they installed it different
and now it turns off if the key is off.  I'm not sure I like that.  What is
standard for this vehicle (as if that matters)?
