SUZCO 100ft 16AWG 6-Wire CCA Trailer Spool - Color-Coded 5-Way

In this review the SUZCO 100ft 16AWG 6-wire trailer spool is evaluated for DIY trailer rewiring and basic towing electrical repairs. The bottom line: it is aimed at hobbyists, RV and boat owners, and small trailer owners who need a long, economical roll of standard 5-way wiring that is simple to identify and install. The single biggest reason to buy is the combination of a full 100 ft length with color-coded 16 AWG copper-clad aluminum conductors that meet SAE J1128 style usage for basic lighting and auxiliary circuits.

Key Features

• 100 ft length: Provides ample wire for multiple rewires or long runs without splicing, reducing time on long trailers or fleets.
• 16 AWG CCA construction: Copper-clad aluminum strands keep weight and cost down while supporting typical trailer lighting loads up to the spool's rated capacity.
• Color-coded 5-way layout: Yellow, green, blue, white and two brown wires are easy to identify for standard 6-wire 6-flat or 5-way circuits, speeding up installation.
• SAE J1128 style insulation: General purpose thermoplastic (GPT) insulation improves resistance to moisture, sun and common garage chemicals for longer service life.
• Uniform gauge and length: All six conductors are the same 16 AWG and equal length, simplifying cuts and end terminations for harnesses and wishbone connectors.

Who It's For

This spool is best for DIYers, RV and boat owners, small-fleet managers and trailer hobbyists who need a long run of standard wiring for lights, brakes and accessory circuits. The 16 AWG gauge and CCA construction suit lighting and low-power auxiliary uses rather than high-current brake systems that require heavier gauge copper.

Those who should look elsewhere include professionals who require full copper conductors for maximum conductivity and longevity under heavy loads, or anyone wiring electric brakes or high-draw accessories that need thicker wire than 16 AWG.

Pros & Cons

Pros

• Good value for length and color coding, making rewires and harness builds straightforward.
• Durable GPT insulation and stranded cores resist moisture and common shop chemicals.
• Meets common SAE-style wiring expectations for 5-way trailer circuits, easing compatibility with standard connectors.

Cons

• Copper-clad aluminum is lighter and less conductive than pure copper, so it is not ideal for high-current applications.

Specifications

Our Verdict

The SUZCO 100 ft 16 AWG 6-wire spool is a practical, cost-effective choice for replacing or building basic trailer lighting harnesses. It offers useful length, clear color coding and weather-resistant insulation, making it a strong value for DIYers and recreational trailer owners who need reliable low-current wiring without the premium cost of full copper.

Frequently Asked Questions

Will this spool work for trailer lights?
Yes, the 16 AWG CCA wires and standard 5-way color layout are suitable for trailer lighting and typical accessory circuits.

Can it be used for electric brakes?
It is not recommended for electric brakes or other high-current circuits; heavier gauge copper wiring is safer for those uses.

Is the insulation weather resistant?
Yes, the GPT insulation is designed to resist moisture, sun and common garage chemicals for outdoor trailer use.
