Lcrslitx 100ft 14-Gauge 7-Wire Trailer Cable Spool — Continuous 7-Conductor CCA, Heavy-Duty Jacket

Lcrslitx 100FT 14-gauge 7-wire trailer cable is a continuous 7-conductor spool designed to rewire trailers, RVs, and tow vehicles with heavy-duty CCA conductors and robust outer jacket.

This spool delivers a full 100-foot run of seven color-coded conductors so you can complete end-to-end trailer wiring without mid-run splices. Built with a higher copper-clad aluminum (CCA) ratio and thicker conductor diameter than typical 14-gauge CCA cable, it offers lower resistance across braking, lighting, and auxiliary circuits while meeting SAE/DOT ratings for towing use. The jacket and insulation resist road hazards and temperature extremes, making routing and long-term service simpler for DIYers and professionals alike.

How does this cable improve signal reliability for trailer lights and brakes?

The Lcrslitx spool uses 30% CCA conductors and a measured conductor diameter larger than common 14-gauge CCA wire, which lowers electrical resistance and stabilizes 12V signals. That reduces voltage drop across long runs so lights and electric brakes respond more consistently. Each spool is continuity-tested to help ensure reliable installations.

• 30% CCA for a thicker copper layer and improved conductivity
• Measured 1.77mm conductor diameter exceeds typical 14-gauge CCA specs
• 600V insulation rating and continuity/insulation testing before shipment

Can I run a full trailer or RV wiring harness from this single spool?

Yes — the continuous 100-foot length is intended to cover entire trailers or small RV rewires without splicing. That eliminates weak splice points and simplifies routing through frames, grommets, and conduits. Color-coded conductors match standard 7-pin blade wiring, so connections are intuitive and quick.

• 100FT continuous run — suitable for multiple full rewires
• Seven SAE-standard colors for straightforward hookups
• Fits through typical 1/2" grommet openings and standard 7-pin connectors

What durability and environmental protections does this cable offer?

The outer PVC jacket is formulated to resist abrasion, oil, salt, and sunlight while maintaining flexibility from cold to hot climates. Premium insulation around each conductor helps prevent shorting and withstands mechanical stress during installation. The cable construction avoids paper fillers; a fine talc lubricant is used internally as a standard, inert manufacturing aid.

• Heavy-duty PVC jacket resists UV, oil, and road salt
• Flexible strand core stays pliable in low temperatures
• Operational range from -15°C to 105°C; 12.45mm overall diameter

Is this wire compatible with standard 7-way connectors and common trailer types?

Yes — conductors follow the SAE 7-conductor color code (Green, Yellow, White, Brown, Blue, Black, Red) used in standard 7-pin blade connectors. It suits a wide range of towing projects including boat trailers, enclosed cargo trailers, horse trailers, RVs, and conversion vans. The spool supports both DIY rewires and professional fleet maintenance.

• SAE-standard color coding for error-free installation
• Suitable for boat trailers, fifth-wheels, campers, and food trucks
• Manufactured and tested to commercial towing standards

Who this is for: installers, fleet mechanics, and DIY trailer owners who need a single, uninterrupted 100-foot 7-conductor cable capable of full rewires. It’s aimed at projects where minimizing splices, improving circuit stability, and withstanding road conditions are priorities — from hobbyist camper conversions to commercial trailer maintenance.
