12-Slot Relay & Fuse Box with 6 Relays and 41 Pins

Organize and Protect Your Vehicle or Boat Wiring

Keep your electrical system clear, accessible and well-protected with this 12-slot relay and fuse box. Designed for automotive and marine applications, it provides a central location for relays and blade fuses, helping you manage add-on circuits, lighting, accessories and repairs without cluttered wiring or loose components.

Engineered around a compact block layout, the box includes 6 relay positions and 6 ATC/ATO standard blade fuse positions, giving you a structured way to route power to multiple devices. The housing is made from durable ABS with metal terminals, suitable for installation in engine bays, under dashboards or in protected marine compartments. A dedicated cable opening at the rear allows all outgoing wires to be bundled into a single harness, improving routing and basic splash and dust protection when used with appropriate loom or sleeving.

The included 41 metallic pins are designed for secure crimp connections to your own wiring (wires not included). Once crimped, the pins are inserted from the back of the box into the corresponding relay or fuse slot, locking firmly in place to reduce the risk of loose contacts. This system supports clean custom installations for lighting systems, auxiliary power, pumps, winches, fans and other 12V circuits, while making future troubleshooting and modifications more straightforward.

Package contents include one 12-slot relay and fuse box and one complete set of terminals as shown in the product images. The universal layout is suitable for most vehicles and vessels using standard automotive relays and ATC/ATO blade fuses. Basic hand tools and crimpers are recommended for installation.
