Enough 100 FT Heavy Duty 14/4 Trailer Wiring Harness - Weatherproof

In this review the Enough 100 ft heavy duty 14/4 trailer wiring harness is examined for RV and trailer owners who need a long, flexible replacement cable for lights and basic hookup circuits. The bottom line: it is best for DIY trailer rewiring and long runs where weather resistance and clearly color-coded conductors matter. The review focuses on build quality, conductor type, and practical installation notes so you can decide if this long, black-sheathed 4-way cable meets your towing wiring needs.

Key Features

• 100 ft length: Provides ample reach for full trailer runs or to keep spare cable on hand for future repairs without needing extensions.
• 14 AWG 4-conductor: Four individually insulated conductors sized for common trailer light circuits so taillights, brakes, turn signals and ground are supported.
• Color-coded wires: Green, yellow, blue and brown insulation simplifies splicing and matching to existing harnesses for faster, less error-prone installations.
• Weatherproof PVC sheath: A flexible black outer jacket resists petrol, oils and diluted acids and helps protect the conductors in outdoor towing conditions.
• Meets SAE J1128 spec: Stranded CCA construction balances flexibility and lower cost while following a common automotive wiring standard for jacketed low-voltage cable.

Who It's For

This cable is aimed at RV owners, trailer DIYers and small shop mechanics who need a long, replaceable run of 4-way trailer wiring for taillights, turn signals and ground. The heavy vinyl outer jacket and rated temperature range make it practical for seasonal and year-round use on towed vehicles.

It is not for high-current accessory circuits, permanent in-body automotive wiring where copper conductors are required, or applications that demand soldered factory terminations. Buyers wanting factory crimped plug assemblies should look elsewhere.

Pros & Cons

Pros

• Durable outer jacket and individual conductor insulation give a weatherproof, long-run solution for trailer lights.
• Clear color coding and stranded construction make splicing and routing straightforward for home installs.
• 100 ft length is convenient for long trailers or keeping spare cable for future repairs.

Cons

• Conductors are copper-clad aluminum (CCA), which is common for economy wiring but may be seen as a drawback where pure copper is preferred.
• Some users reported mixed wire bonding at splice points, so expect to tidy splices during installation for best results.

Specifications

Our Verdict

The Enough 100 ft 14/4 harness is a practical, value-oriented choice for trailer and RV light circuits where long runs and weather resistance matter. It offers straightforward color coding, a robust outer jacket and enough flexibility for neat routing. Buyers who need pure copper conductors or factory-terminated plugs should consider alternatives, but for most DIY towing wiring jobs this cable delivers strong utility and good value.

Frequently Asked Questions

Can this cable be used for brake and turn signals?
Yes; the 4 conductors are intended for tail lights, driver-side and passenger-side stop/turn circuits and ground when spliced into the trailer harness.

Is the outer jacket weather resistant?
Yes; the black PVC sheath is rated to resist petrol, lubricating oils and diluted acids and is suitable for outdoor trailer use.

Are the conductors copper?
The conductors are stranded copper-clad aluminum (CCA) meeting SAE J1128, which provides flexibility and lower cost compared with solid copper.
