HiFind 14 Gauge 6-Way Trailer Wiring Harness 25 ft — Bonded Flat CCA Stranded, Weather-Resistant

HiFind's 14 gauge, 25 ft 6-way bonded trailer wiring harness is a flat, CCA stranded cable kit that consolidates ground, running lights, turn signals, electric brake, and 12V power into one easy-to-run assembly for standard 12V towing and RV electrical needs.

This harness is designed for installers who need a durable, neat, and thicker-than-standard wire solution for trailers, campers, boat trailers, and other 12V vehicle projects. The cable uses 14AWG stranded copper-clad-aluminum conductors bonded side-by-side into a flat ribbon for tidy routing and simple threading through chassis channels. The outer PVC jacket protects the conductors from moisture, UV, oil, and abrasion while the white ground wire is the same heavy gauge to reduce corrosion and improve ground reliability.

How does this harness make trailer wiring faster and tidier?

The bonded flat design bundles six color-coded conductors into a single assembly that feeds through tight spaces without tangling. This eliminates the need to run six separate cables and reduces time spent sealing and supporting individual wires.

• Flat ribbon layout for easy threading through grommets and channels
• Color-coded conductors reduce identification and hookup time
• 25 ft length covers most trailer and RV runs without splicing
• Bonded conductors stay aligned for straightforward routing and fastening

Will this cable handle electric brakes and long runs better than 16AWG?

Yes. At 14AWG stranded, the harness offers lower resistance and higher current capacity compared with 16AWG, which improves voltage stability on long runs and when powering brake controllers and auxiliary loads. The stranded CCA construction balances conductivity and lower weight.

• 14AWG reduces voltage drop on long trailer runs
• Stranded conductors flex for vibration resistance under chassis
• CCA (copper-clad aluminum) keeps weight down while remaining cost-effective

Is the harness durable enough for outdoor and under-vehicle use?

The harness meets SAE J1128-compatible performance expectations and is wrapped in a rugged PVC jacket rated for -40°C to +105°C. It’s formulated to resist water, UV, oil, grease, acids, wear, and vibration common on trailers and towing vehicles.

• Weatherproof PVC insulation for wet, sunny, or cold conditions
• Oil and acid resistance for under-chassis longevity
• High mechanical wear and vibration tolerance for road use

Which wires are included and what do the colors mean?

The kit includes six bonded conductors, each color-coded for common trailer functions so you can hook up lighting, ground, brakes, and auxiliary power without guesswork. The white ground is 14AWG like the others for consistent grounding performance.

• White — Ground (14AWG)
• Brown — Tail / Running Lights
• Yellow — Left Turn Signal
• Green — Right Turn Signal
• Blue — Electric Brake Controller
• Red — 12V Battery / Auxiliary Power

Who is this for: Installers, DIY trailer owners, RV technicians, and boat or ATV trailer builders who want a heavier-duty, easy-to-route wiring solution for standard 12V lighting, brake, and auxiliary circuits. This harness is especially useful when replacing degraded multi-wire runs, installing electric brakes, or building a new trailer where neat routing and reduced voltage drop matter. HiFind backs the product with a 2-year warranty for quality-related issues and provides customer support for installation questions or replacement needs.
