Product Details
✓Utility Relay and Fuse Box: The Nilight 12V relay box is designed with 4pcs 40A 4-pin relays and 12 fuses, meeting basic circuit wiring needs and allowing connection of up to 12 circuits. Please connect the appropriate load according to the fuse on each circuit. 4 spare fuses are included for easy replacement as needed. When replacing fuses, it is recommended to use fuses with a smaller or the same rating
✓High Performance: The relay box housing is made of high-quality flame-retardant nylon, and the top cover is dustproof and splash-proof (but not submersible). Its compact design allows multiple circuits to be integrated into one box, making the wiring environment neater and more organized, and facilitating the installation of various accessories in your vehicle. All the wires come out from two cable outlet holes, making it more convenient to use
✓Pre-wired Design: This relay fuse box features a pre-wired design with color and number coding for easy identification and connection. The 18AWG white wire connects to the switch (-), and the 12AWG yellow and blue wires connect to the load (+). The relay numbers correspond to the white and yellow wires, and the fuse numbers correspond to the blue wires, helping you easily track multiple independent circuits for time-saving installation
✓Wide Application: This automotive relay box is designed to improve safety and protect equipment from potential damage. It is suitable for installing on most 12V vehicles such as cars, pickups, trailer, campers, marine, boats, ATVs, UTVs, etc. The mounting holes on both sides of the box and the included screws provide a easy installation solution
✓Package Includes: 1 x Pre-wired Fuse Relay Box with Top Cover, 4 x 4Pin Relays, 12 x Blade Fuses (10A*3, 20A*3, 25A*3, 30A*3), 2 x Mounting Screws and Nuts, 4 x Spare Fuses (10A*1, 20A*1, 25A*1, 30A*1), 1 x User Manual
