Little Fuse is the brand name of the fuses I recommend. Most auto parts stores sell BUSS name brand fuses. Does not mater if you use the standard or mini size. The fuse holders are what you get buying at the auto store. I would stick with 20 amp fuses which will run cooler than 15 amp fuses. The fuse is mostly just to protect from a short circuit. Fuses are not really quick enough to protect electronics or fan motors.
