Truck Power Harness with Fuse Box & Rocker Switch SW-O-16 — Pre-Wired Power Feed, Protection & Control in One Assembly

SW-O-16 Truck Power Harness — One Assembly Replaces Three Purchases: Feed, Fuse, Switch

Adding electrical accessories to a truck or trailer — work lights, beacons, compressors, tail lift controls — usually means sourcing three separate things: a power feed cable, an inline fuse holder, and a switch, then splicing them together on a bench and hoping the joints survive road vibration. The Snowwolf SW-O-16 consolidates all three into one factory-built assembly: a truck power harness with integrated fuse box, rocker switch and terminal connectors, pre-crimped, pre-wired and ready to drop into the vehicle's electrical system.

The value is in the integration done at the factory, not in the field: the fuse box protects the circuit at the correct point — close to the power source, where it actually prevents harness damage; the rocker (boat-shaped) switch gives the driver positive on/off control from the cab; and factory-crimped terminal connectors eliminate the field-spliced joints that corrode and loosen first. One honest note before ordering: fuse rating and wire gauge must match your accessory load — tell us what the circuit feeds (lights, compressor, pump) and the vehicle voltage (12V or 24V), and we confirm the configuration before production. Wire length, fuse rating and switch position are customizable.

The SW-O-16 is produced in our ISO/TS 16949-certified factory in Dongguan with a 1-year warranty. Orders start at 100 pieces at $5.60/piece FOB Shenzhen, with 15–25 day delivery, L/C or T/T payment and private labeling available. Send us your accessory load and vehicle platform — quotations return within 24 hours.
