All Star Truck Parts 7-Way 14 Gauge Trailer Wire 100 ft Roll — Color-Coded Pure Copper, Heavy-Duty Flexible

All Star Truck Parts 7-conductor 14 gauge trailer wire is a 100-foot roll of color-coded, stranded pure copper cable designed for RVs and trailers and built to DOT FMVSS 108/SAE PC P2 specifications.

This heavy-duty 7-way conductor cable brings together stranded 14 AWG pure copper conductors with a flexible PVC jacket to give professional installers and DIYers a reliable, weather-resistant wiring solution. The seven individually insulated wires—green, yellow, white, brown, blue, black, and red—are bundled inside a single jacket for neater routing and faster installations on trailers, campers, and towing rigs. Rated for flexibility down to -40°C and engineered to resist oil, grease, and outdoor exposure, the roll is suitable for harsh road conditions and long service life.

How does this 7-way cable simplify trailer wiring?

The integrated 7-conductor design reduces the time and clutter of running separate wires. Each conductor is color-coded to standard SAE/DOT assignments so you can quickly identify connections and avoid cross-wiring during installation or repairs. The single-jacket format also protects all seven conductors from abrasion and moisture better than multiple loose wires.

• Seven conductors in one jacket for tidy routing and faster installs
• Color-coded insulation matches SAE/DOT wiring conventions
• 100-foot roll lets you cover most trailer lengths without splicing
• PVC outer jacket protects against abrasion and moisture

Will this wire withstand cold, oil, and road conditions?

Yes. The cable uses a PVC jacket and stranded copper conductors engineered to remain flexible at temperatures as low as -40°C, reducing the chance of cracking in cold climates. The materials are selected to resist oil, grease, salt, and everyday road grime, which helps preserve electrical integrity and extends service life on tow vehicles and trailers.

• PVC jacket stays pliable down to -40°C for cold-weather durability
• Resistant to oil, grease, and weather exposure for roadside reliability
• Stranded pure copper conductors maintain conductivity under vibration
• Meets PC and P2 DOT FMVSS 108/SAE requirements for compliance

Is this 14 gauge wire suitable for RV and trailer electrical needs?

Fourteen-gauge stranded wire is commonly used for lighting, turn signals, brake lights, and auxiliary circuits where moderate current capacity is required. The full-stranded pure copper conductors provide improved flexibility and lower resistance compared with tinned or composite options, making them a practical choice for typical trailer lighting and control circuits on most recreational and utility trailers.

• 14 AWG stranded copper supports lighting and control circuits effectively
• Color-coded conductors match trailer light and brake circuit layouts
• Stranding improves flexibility for routing through tight spaces or grommets
• 100% copper conductor ensures consistent conductivity over length

How easy is installation and what should I expect?

Installation is straightforward: unroll the cable, route it along the trailer frame, and use the color-coded wires for clear, standardized connections. The stranded conductors accept crimp or solder terminations; use appropriate terminals, heat-shrink, and corrosion protection at connection points for best results. For long runs, plan mounting points and protective grommets where the wire passes through metal or near moving parts.

• Single-jacket roll reduces routing time versus individual wires
• Works with common crimp terminals and soldered joints
• Use grommets and clamps where the cable contacts metal or moves
• 100 ft length minimizes the need for splices on most trailers

Who is this for? This 100 ft roll from All Star Truck Parts is aimed at RV owners, trailer builders, fleet technicians, and DIYers who need a durable, code-compliant wiring solution for lighting and control circuits. If you want a neat, single-jacket harness with 100% stranded copper conductors, clear color coding, and cold-weather flexibility that meets DOT FMVSS 108/SAE PC P2 standards, this cable is designed for your towing and trailer wiring projects.
