Purpose Of A 12V Fuse Panel
In a van conversion, you are likely going to have multiple 12V devices. Such devices can include LED lights, vent fan, water pump, diesel heater, and more. Instead of wiring every single device directly to the battery, fuse blocks simplify the wiring process by allowing you to connect all 12V devices to the block and then only wiring the block to the battery (or better, bus bars).
