One like this will work very good. Simply remove the wires from the easiest post, either negative or positive. Install wires on to switch.
This as simple as it gets but the downside is if the battery is located within a battery box with a strap around it you have to open that box every time you want to engage or disengage the switch. Any tongue mounted battery I've owned has been in a box so I instead mounted a Blue Sea battery switch on the end of the box - much more convenient. :)
