I've used a cutoff switch between the battery and the ground for several years in my roadster. The battery is trunk mounted and a short - wire leads to the cutoff then grounds to the frame. While it isn't mounted anywhere you can turn it off easy, it does work as a theft device just in case. Regardless of which side you mount it, or where you mount it, you can run a thick wire over the top with a 3 amp fuse between the posts on the cutoff switch and it will allow your clock or such to stay on but will blow if someone trys to hotwire your car. This will let you have theft deterant plus your low amp draw. Best is between the seats. Also best to spend the big bucks and buy a quality cutoff switch.
Another method is to splice into the little wire that charges your coil and attach it to a dimmer switch (dedicated solely for this) or other quality switch that can be hidden under a carpet. You know where it is but it isn't visable, and no one would be the wiser as to why it won't start. Assuming you don't forget.....
