Highway 22 Modular Wiring Kit Truck Mount

The Highway 22 Modular Wiring Kit Truck Mount from American Autowire is purpose-built for truck enthusiasts and professional fabricators who demand a clean, organized electrical foundation for custom builds and modifications. Whether you're installing aftermarket lighting, winches, auxiliary power systems, or integrating modern electronics into classic truck platforms, this modular approach eliminates the guesswork and time-consuming wire runs that plague traditional point-to-point harnesses. The truck-specific mounting design accommodates the dimensional and routing constraints of pickup bed and cab configurations, making it an essential starting point for any serious truck electrical upgrade.

This modular architecture allows you to build exactly the circuit configuration your truck requires—adding only the circuits and gauge combinations you need rather than paying for unused capacity in prepackaged harnesses. The kit's compact footprint of 7 × 4 × 13 inches and 7.15-pound weight makes it easy to route through tight engine compartments, under beds, and through firewalls without sacrificing wire quality or amperage capacity. American Autowire's highway-duty construction ensures reliable performance in high-vibration, temperature-variable truck environments where inferior harnesses fail within seasons. The modular connectors and color-coded terminals reduce installation errors and enable future modifications without complete rewiring.

Mechanics, fabricators, and truck owners tackling restorations, performance upgrades, or electrification projects benefit most from this kit's flexibility and build quality. It pairs seamlessly with auxiliary relay panels, fused distribution blocks, and aftermarket control modules—the backbone of any modern truck electrical system. Installation requires basic electrical knowledge and standard crimping tools; the modular design means you can tackle the project in stages, testing and validating each circuit independently before moving to the next. Compatibility extends across most truck platforms where a custom harness approach is preferable to manufacturer limitations or obsolete original wiring.
