If you have a battery box, you can mount in top of box. Just wire in series with the positive terminal. Mine uses switch below. The red handle is removable to prevent tampering. While you are working in the area, I recommend replacing the glass fuse holder with an automotive blade style holder and a 30 amp plug in breaker. By using the plug in option you can alwas use a standart fuse if the breaker dies in a remote location.
