Enough Long 400FT 14 Gauge 6 Way Trailer Wire Spool - Color-Coded

In this review the Enough Long 400FT 14 Gauge 6 Way Trailer Wire spool is evaluated for DIY trailer, RV and hitch wiring jobs; the bottom line is that it is a practical, economical choice when you need a lot of color-coded wire on a single spool. The single biggest reason to buy is the combination of a full 400 ft length and the standard six-way color coding, which makes rewiring or extending trailer circuits straightforward for anyone comfortable with basic splicing and connectors. The review notes build quality, ease of identification, and where the spool fits in a typical trailer wiring project.

Key Features

• 400 ft spool: A long continuous length reduces the need to join multiple runs and is handy for rewiring larger trailers or keeping spares.
• 6-way color coding: Standard colors for ground, tail, turn and stop circuits make identification and splicing faster and less error prone.
• 14 AWG heavy duty: The thicker 14 gauge construction supports loads up to about 120W, which covers typical lighting and small auxiliary circuits.
• Meets SAE J1128: The wiring meets or exceeds common automotive trailer standards for construction and insulation performance.
• PVC insulation: A PVC jacket helps resist rain, moisture and sunlight exposure for routine exterior use.

Who It's For

This spool is best suited to DIYers, trailer shops and fleet owners who need a cost-effective way to rewire trailers, campers, hitches or ATVs. The continuous 400 ft length is convenient for projects that require long runs or multiple trailers and for users who prefer to cut their own lengths and make clean splices.

It is less appropriate for installers who require factory-terminated harnesses or for circuits with higher continuous current demands beyond standard lighting and small auxiliary loads; in those cases a heavier gauge or pre-assembled harness may be a better fit.

Pros & Cons

Pros

• Full 400 ft spool provides excellent value and reduces the need for multiple purchases.
• Standard color coding simplifies wiring tasks and lowers the risk of wiring mistakes.
• 14 AWG copper-clad aluminum construction balances weight and conductivity for lighting circuits.
• Durable PVC insulation resists common outdoor elements for trailer use.

Cons

• Copper-clad aluminum is not pure copper, so users wanting maximum conductivity or soldering characteristics may prefer solid copper wire.
• Not a plug-and-play harness; it requires cutting, splicing or connectors for finished installations.

Specifications

Our Verdict

The Enough Long 400FT 14 Gauge 6 Way spool is a solid value for anyone who needs a large quantity of standard trailer wiring for lights and small auxiliaries. It is practical for DIYers and shops because of the clear color coding and durable insulation, and it stretches further than typical short spools. Buyers who need solid copper conductors or pre-terminated harnesses should look elsewhere, but for general trailer rewiring this spool offers dependable performance and good value.

Frequently Asked Questions

Is this wire suitable for trailer lighting?
Yes, the 14 AWG 6-way color-coded wiring is intended for trailer lighting, turn, stop and auxiliary circuits up to typical lighting loads.

What do the wire colors mean?
Standard assignment: white is ground, brown is tail/running lights, yellow is left turn, red is stop, blue is auxiliary, and green is right turn.

Can I solder or crimp this wire?
Yes, you can crimp or solder, but note the conductor is copper-clad aluminum rather than pure copper, which affects soldering behavior and you should use appropriate connectors and techniques.
