I think the sound is coming from inside the engine bay, it sounds like it is emitting from underneath the intake/engine cover.
I had the hood open today and had someone in the car while it was running, when they turned the car off, the sound continued for about 2-3 seconds.
Try it and you'll see what I mean. It's a constant hi-pitched sine wave sound though. I originally thought this was coming from some electrical component behind the dash, now it seams like it is from the engine bay, and I'm just hearing it coming through the dash.
