The black cover is under the dash it covers the top of the gas pedal and brake and coluum it has a couple of screws that hold it in, if u can see youre fuse block under there than u dont have the cover. The little chime is to the right of the vent under the coluum. reach youre hand up there just left of the diagnostic plug and just unplug it. It will be deep in there.
Honestly i think it is a good feature, but like trixsix says it will help u out when you leave youre lights on or forget the keys are in the ignition.
