The American Autowire Highway 15 Plus Universal Wiring System (AAW510825) is a 15-circuit universal wiring kit designed to modernize and streamline the electrical foundation of custom vehicles. Originally introduced in 2003 as the Highway 15, this updated “Plus” version features significant enhancements while maintaining the compact design ideal for tight spaces in kit cars, roadsters, and coupes. With user-friendly features such as self-locking wire terminals, color-coded labeled wiring, and a detailed instruction manual, it provides an efficient and reliable solution for both DIY enthusiasts and professional builders.
KEY FEATURES AND BENEFITS:
- Compact Design for Tight Spaces: Small fuse panel footprint (4.5″ L x 4.5″ W x 3.5″ H) makes it ideal for hot rods, coupes, and other vehicles with limited space.
- Simplified Installation: Self-locking screw-clamp terminals secure wires without crimping tools. Pre-labeled, color-coded wires and step-by-step instructions ensure ease of installation.
- Modern Vehicle Component Support: Built-in LED flasher compatible with LED and incandescent turn signals, plus a high-amp alternator connection kit with dual 175-amp MegaFuses for system protection.
- Enhanced Functionality: Includes extra connectors and wiring to support four-headlight systems, backup lights, and accessory power without additional purchases.
SPECIFICATIONS:
- Fuse Panel Material: G-10 composite base with nylon 6/6 components
- Wire Type: GXL/XLPE GM color-coded wire with labeling every 3–4 inches
- Product Includes:
- Main fuse panel with self-locking screw-clamp terminals
- Ignition, headlight, and floor dimmer switches
- GM-style steering column connector kit
- High-amp alternator and main power connection kit
- Full-color, tabloid-sized, step-by-step instruction manual
- Built-in horn, turn signal relays, and LED flasher
HOW TO USE:
- Initial Planning: Read the instruction manual and lay out all components before beginning installation.
- Mount the Fuse Panel: Select a dry, secure, and accessible location for the compact panel and mount with the included hardware.
- Run Main Power: Install the high-amp alternator and power kit. Connect the 6-gauge wire from alternator and battery to the panel using the dual 175-amp MegaFuses.
- Connect Vehicle Circuits: Route pre-labeled wires to each component (headlights, signals, gauges) and secure them to the fuse panel with screw-clamp terminals.
- Connect Switches and Column: Install ignition, headlight, and dimmer switches. Use the GM-style connector to wire turn signals and horn.
- Test and Secure: Test all systems for functionality, then tie up loose wires for a professional finish.
