You can use a fusible link or an inline fuse on the "in" to ammeter. Fusible links are sized 4 wire gauges less than wire gauge. Example: 10 gauge wire, you buy a 14 ga fusible link. A fusible link is a piece of wire with special insulator. Wire will melt before insulator. It is not really necessary to have a "fuse" there as the ammeter measures current, doesn't draw. But theories abound so use a "fuse" if you wish. As you see the "out" (not using "input or "output" terms), goes to the fuse panel. So most components are fused there. Other components on the out side, like headlight switch, have a built-in fuse. Nothing to worry about, just wire it up. You won't be Fireball Roberts. 10ga or larger is usually recommended for in/out. Search internet for a bunch of info and sort out what most say to get a consensus and be comfortable with what we say.
