All Star Truck Parts 14-Gauge 7-Conductor Trailer Wire — 50 ft Roll, 100% Stranded Copper, Weatherproof PVC

All Star Truck Parts 14-gauge 7-conductor trailer wire is a 50-foot roll of stranded, 100% pure copper cable with a weatherproof PVC jacket and SAE/DOT-compliant color coding for reliable RV and trailer wiring.

This heavy-duty 7-way cable combines seven insulated conductors inside a single flexible jacket, built for towing, RV hookups, and fleet use where durability and regulatory compliance matter. The stranded copper conductors maintain conductivity while remaining pliable in cold conditions, and the jacket resists oil, grease and weather exposure. It carries PC and P2 ratings to meet DOT FMVSS 108 / SAE wiring standards so you can wire lights and auxiliary circuits with consistent, code-aligned color identification.

What makes this 7-conductor cable suitable for trailers and RVs?

The cable integrates seven individually insulated wires—green, yellow, white, brown, blue, black, and red—inside a single outer jacket so routing and installation stay tidy. Stranded pure copper conductors offer better flexibility and vibration tolerance than solid wire, reducing breakage risk on moving connections.

• Seven color-coded conductors for standard trailer functions
• Stranded 14 AWG pure copper for conductivity and flexibility
• PVC jacket resists oil, grease and weathering
• 50-foot roll for long runs without splices

How does it perform in cold or harsh environments?

The PVC insulation and jacket remain flexible at low temperatures, so the cable won’t stiffen and crack when used in winter conditions. The stranded construction also withstands constant movement and vibration common in towing applications.

• Flexible down to -40° C for cold-weather reliability
• Jacket resists abrasion, oil and grease exposure
• Stranded conductors reduce fatigue from vibration and bending

Is this cable compliant with DOT and SAE wiring standards?

Yes. The roll is manufactured to meet PC and P2 ratings under DOT FMVSS 108 and SAE guidelines, and the conductors follow standard trailer color codes for quick identification and safe hookups. Using a compliant cable helps ensure compatibility with trailer lighting and electrical systems.

• PC and P2 rated to align with FMVSS 108 / SAE specs
• Standard color coding for direct replacement or upgrades
• Suitable for brake, signal, tail, auxiliary and ground circuits

How easy is installation and what are typical uses?

The single-jacket design simplifies routing along frames or into junction boxes, and the 50-foot length covers many common trailer and RV runs without additional splices. Installers can strip, crimp, solder or use connectors as needed for lights, brakes, aux power, or custom wiring projects.

• 50-foot spool reduces need for multiple joins
• Compatible with common connectors, terminals and splice techniques
• Ideal for RVs, utility trailers, horse trailers, and fleet vehicles

Who this is for: This All Star Truck Parts 7-way 14-gauge roll is aimed at professional mechanics, fleet maintenance teams, DIY RV owners, and trailer builders who need a durable, code-compliant cable for lighting, auxiliary circuits and brake systems. Choose this spool when you want a long, flexible length of stranded copper conductors in standard color codes for straightforward, long-lasting trailer electrical work.
