About this item

  • 【PLUG PLAY WITH DIY】Ready to install right out of the box. This 6-way fuse and relay module kit includes four 4-pin 40A JD1912 relays and six ATC/ATO blade fuses (5A, 10A, 15A, 20A, 25A, 30A). Four circuits come pre-wired for immediate use, while the remaining two slots include fuses and separate terminal blocks, giving you the freedom to customize your wiring setup as needed
  • 【SAFE OPERATING CURRENT】This fuse box capacity is 64A, with up to 25A per pre-wired circuit. The included fuses (5A-30A) offer DIY flexibility, not simultaneous capacity. To prevent overheating, try to stay 10% to 15% below the rated amperage. (Need custom wire gauges for heavier loads? We also offer a standalone unwired box, allowing you to fully customize your own wires and fuses)
  • 【DUSTPROOF SHELL】Features a secure top cover that effectively blocks dust, dirt, and debris while protecting active circuits from accidental contact. NOTE: This unit is strictly dustproof and can handle light water splashes, but it is NOT completely waterproof. Please mount it in a dry location, such as the cabin or a protected under-hood area, away from direct rain or submersion
  • 【DOUBLE PROTECTION】Engineered for ultimate electrical safety. The four pre-wired relays are connected in series with the fuses, delivering reliable double overcurrent protection for your circuits. A highly versatile 12V power management solution perfectly suited for headlights, fog lights, air horns, fuel pumps, cooling fans, LS swaps, and custom aftermarket builds on 4x4s, trucks, SUVs, and RV trailers
  • 【VERIFY MOUNTING CLEARANCE】To ensure a seamless installation, please carefully review the product dimensions shown in the listing images prior to purchase 134mm x 80mm x 70mm (5.28″ x 3.15″ x 2.76″). Confirm that your vehicle has adequate mounting clearance—whether under the hood, under the dash, or in the trunk—to accommodate both the box's overall footprint and the necessary space for the bottom wire exits
