100FT 6 Wire Trailer Wire 14 Gauge CCA Spool - Durable 6-Way Harness

In this review the 100FT 6 Wire Trailer Wire spool is judged as a practical, no-nonsense wiring solution for anyone rewiring a trailer or adding basic 12V circuits. The bottom line: it is best for owners who need a long, color-coded, multi-conductor cable to simplify trailer wiring, with the single biggest reason to buy being its 100 ft length combined with clear color coding that makes separating and routing individual 14 gauge lines straightforward and dependable.

Key Features

• 100 ft length: Provides ample reach for large trailers, RVs or boat trailers so you can run continuous runs without splicing multiple shorter cables.
• 14 gauge CCA conductors: The 14 gauge copper-clad aluminum construction balances conductivity and weight for typical 12V trailer circuits while keeping the spool manageable.
• Color-coded wires: Six distinct colors (green, white, brown, yellow, red, blue) simplify identification and reduce installation errors when separating individual conductors.
• Black jacket with bonded cores: A single black outer jacket holds the six parallel cores together for easier routing along a frame and extra mechanical protection.
• SAE J1128 compliance: Built to the referenced wiring standard and supplied with PVC insulating tape to finish terminations and protect splices.

Who It's For

This spool is ideal for DIYers and professionals tackling general trailer rewiring, wiring conversions on campers and RVs, or building multi-function harnesses for boat trailers and ATVs. The long 100 ft run and six conductors mean fewer splices and the ability to reach from vehicle to the far end of longer trailers.

It is less suitable for high-current applications that demand pure copper conductors or for users who need factory-style molded connectors; those users should consider full copper cable or pre-molded harness assemblies. For standard 12V lighting, brakes, and accessory circuits this spool is an efficient, cost-effective choice.

Pros & Cons

Pros

• Good value for length and function with 100 ft of 6-conductor cable for many wiring layouts.
• Color-coded conductors and a bonded black jacket make routing and identification quick and reliable.
• Complies with SAE J1128 standards and includes PVC insulating tape for finishing connections.

Cons

• Uses copper-clad aluminum (CCA) rather than solid copper, which is reasonable for 12V lighting but not ideal for very high-current runs.

Specifications

Our Verdict

The 100FT 6 Wire Trailer Wire spool is a sensible, budget-aware pick for anyone needing a long, color-coded 6-way harness for standard 12V trailer systems. It delivers practical flexibility, clear conductor identification and compliance with wiring standards, making it a strong value for trailer owners, RV hobbyists, and installers who do not need heavy-duty solid copper for high-current circuits.

Frequently Asked Questions

Can the spool be split into single wires?
Yes; the bonded multi-core spool is designed so individual conductors can be separated and used as single wires for specific circuits.

Which color is ground and which is brakes?
The white conductor is the ground wire and the blue conductor is intended for electric brakes, per the color-coding provided.

Is this cable suitable for long high-current feeds?
For standard lighting and accessory 12V circuits it is suitable, but for long runs requiring high current, a solid copper gauge larger than 14 should be considered.
