This 12V relay fuse box is designed to organize relay-controlled accessory circuits in compatible vehicle and low-voltage electrical systems. It includes six 4-pin 40A relays and multiple ATC/ATO fuse slots, helping combine switching control and circuit protection in one compact housing. The pre-wired harness uses color-coded leads for easier identification during installation, while the 12 AWG high-power wiring supports safer current handling for compatible loads. This relay box is suitable for auxiliary lights, fans, pumps, horns, compressors, and other vehicle accessories in trucks, SUVs, UTVs, ATVs, RVs, trailers, campers, and boats.
