Here is how I installed a master switch AND don't lose my presets. Run a wire from the + terminal of the battery to an inline fuse. Now run a wire from the inline fuse to the fuse for the radio. Take the fuse out of # 11 and connect to the LOAD side. Use the same size, 30 A, and a heavy wire. Just be aware that even with the master switch off you are still drawing a small amount out of the battery. Not much but still a draw. If the car is not used much you should trickle charge the battery once a month for a day. If you are really lazy (I'am kidding) you can drill a hole in the battery cover and extend the master switch handle through so you can just reach behind the passenger seat to get the switch without removing the cover. There are master switches with a removeable key so it can be inserted through the hole and removed when you leave the car. The reason our cars seem to "eat batteries" is because it hurts the life of a battery not to always be fully charged. If a car is used infrequently the battery lives in a chronic state of undercharge. A discharged battery can also freeze which is DEATH to a battery.
