All Star Truck Parts 7-Way 14-Gauge Trailer Cable — 50 ft Roll, 100% Stranded Copper, Weather-Resistant PVC

Heavy-duty 7-conductor 14-gauge trailer cable, 50 ft roll, with stranded 100% copper conductors and a weather-resistant PVC jacket for reliable RV and trailer wiring.

This All Star Truck Parts 7-way trailer cable is built for rigors of towing, offering seven color-coded stranded copper conductors inside a single insulated jacket. Engineered to meet DOT FMVSS 108 and SAE PC/P2 ratings, the cord balances flexibility in cold weather with durable resistance to oil, grease and road elements. It’s supplied on a 50-foot roll to fit most towing setups and simplifies trailer wiring runs with clear color identification for each circuit.

How does this cable stand up to harsh weather and road conditions?

The outer PVC jacket and stranded copper cores are chosen to endure temperature swings and exposure without cracking or losing conductivity. The materials resist oil, grease and common environmental wear so the cable remains flexible down to -40°C and continues conducting safely.

• PVC jacket resists abrasion and chemicals
• Flexible stranded copper maintains conductivity in cold
• Color-coded conductors reduce wiring errors during installation

What makes this 7-way 14-gauge cord compliant with DOT/SAE standards?

Each conductor is sized and insulated to meet the PC and P2 requirements in FMVSS 108 and corresponding SAE specifications for trailer lighting and auxiliary circuits. The product is manufactured to the electrical and mechanical tolerances expected for road-legal towing accessories.

• Meets FMVSS 108 PC/P2 ratings for trailer lighting circuits
• Color coding aligns with SAE wiring conventions
• Stranded pure copper conductors for consistent electrical performance

How easy is installation and what wiring does the cable include?

The single-jacket construction with seven individually insulated wires reduces the time and complexity of routing and securing multiple separate cables. The conductors are color-coded (green, yellow, white, brown, blue, black, red), matching standard trailer wiring assignments for quick, accurate connections.

• 7 conductors in one jacket simplify routing and protection
• Standard color scheme for quick identification
• Available in a 50 ft roll to reach most vehicle-trailer configurations

Will the cable handle the electrical load for lights and auxiliary circuits?

Fourteen-gauge stranded copper is appropriate for lighting circuits and typical trailer accessories on a 7-way harness. The stranded construction improves current capacity under vibration and movement compared with solid wire and helps prevent breakage at stress points.

• 14 AWG sizing suitable for lighting and auxiliary functions
• Stranded copper for durability under vibration
• 100% copper conductor for efficient power delivery

Who this is for: Tow vehicle owners, RVers, fleet maintenance teams and DIY trailer builders who need a durable, code-compliant 7-way cable that’s easy to route and identify. Choose this 50 ft roll when you want a single, flexible jacketed solution made with stranded pure copper to meet DOT/SAE specs and hold up to road and weather demands.
