Lcrslitx 7-Wire Trailer Cable 100FT Spool — 14-Gauge 7-Way CCA with Heavy-Duty Flexible Jacket

Lcrslitx 100FT 14-gauge 7-wire trailer cable is a continuous, heavy-duty 7-way wiring spool engineered for full trailer rewires and large towing projects.

This 100-foot continuous spool supplies seven color-coded conductors on a single durable jacket, letting you rewire an entire RV, horse trailer, camper, or commercial trailer without mid-run splices. The cable uses 30% CCA conductors with a thicker copper layer than typical CCA wire, a heavy PVC outer jacket rated for harsh environments, and dimensions that exceed standard 14-gauge specifications. It’s built to be flexible for routing through tight chassis spaces, resistant to oil and road salt, and compliant with SAE wiring color conventions for quick installation.

How does this cable stand up to road and weather exposure?

The outer PVC jacket is engineered for durability in towing conditions, resisting UV, salt, oil, and abrasion while remaining flexible from -15°C to 105°C. The insulation thickness and jacket diameter add mechanical protection for long runs along frames and under trailers.

• 12.45mm overall diameter for rugged protection
• 0.76mm premium insulation per conductor for higher dielectric strength
• Rated for -15°C to 105°C operating range
• Resists road salt, oil, UV, and abrasion for longer life

Is the electrical performance reliable for brake lights, turn signals, and auxiliary circuits?

Yes — the spool uses 30% CCA conductors with a measured conductor diameter of 1.77mm, which exceeds typical 14-gauge measurements and lowers circuit resistance. Each conductor is individually insulated and the full assembly is rated for 600V, improving signal stability for 12V systems used in towing applications.

• 30% CCA formulation for a thicker copper layer and improved conductivity
• 1.77mm measured conductor diameter (above industry 14-gauge spec)
• 600V rating and continuity testing before shipping
• Consistent performance across seven circuits for lights and brakes

Will this cable make installation faster and less error-prone?

The seven conductors are color-coded to SAE industry standard so you can identify circuits quickly without relying on external diagrams. The 100-foot continuous length eliminates mid-run splices for most full-trailer applications, saving time and reducing potential failure points.

• SAE-standard color coding: Green, Yellow, White, Brown, Blue, Black, Red
• 100FT continuous spool covers 2–3 full trailer rewires
• Fits standard 1/2-inch grommeted holes and common conduit paths
• Pre-shipment continuity and insulation integrity checks

What types of trailers and projects is this spool best suited for?

This wiring spool was designed for medium-to-large towing projects where a complete, continuous run is preferred. It’s a practical choice when reliability and reduced resistance matter for longer cable runs and heavier trailer systems.

• Full rewires for RVs, fifth wheels, and 40-foot trailers
• Horse and livestock trailers with dual axles
• Boat and pontoon trailer electrical systems
• Food trucks, utility trailers, and camper van builds

Who is this for? This Lcrslitx 100FT 14-gauge 7-wire spool is aimed at DIY mechanics, trailer service shops, and fleet operators who need a long, single-run wiring solution that minimizes splices and improves electrical stability. If you’re rewiring an entire trailer, upgrading older 7-way wiring, or building out a large towing setup where durability and clear circuit identification matter, this spool provides the length, ruggedness, and conductor quality to complete the job cleanly and reliably.
