Harness Kit, 25' 5-Way

This Harness Kit with 25-foot length and 5-way wire configuration delivers the complete wiring solution Southeast Louisiana boat trailer owners need for reliable lighting system installation and replacement. Manufactured by Donovan Marine, this kit includes everything necessary for professional-quality trailer wiring: the main 25-foot harness with five color-coded circuits, junction box connectors, and mounting hardware designed to withstand Louisiana's humid coastal environment. The 25-foot length accommodates most single axle and smaller tandem axle trailers operating at launches throughout Westwego, Bayou Segnette State Park, and Lake Pontchartrain, eliminating the need for extension splices that create weak points vulnerable to saltwater corrosion. Whether you're replacing a complete wiring system damaged by years of Gulf Coast saltwater exposure, upgrading an older trailer with inadequate electrical components, or performing new trailer builds requiring DOT-compliant lighting, this kit provides the comprehensive wiring solution Jefferson Parish boat owners depend on for safe operation across Greater New Orleans.

Louisiana boat trailer owners understand that electrical systems are constantly challenged by the combination of saltwater spray during launches, humid coastal conditions that accelerate wire corrosion, and the intense Louisiana sun that degrades insulation over time. This Donovan Marine harness kit addresses these environmental factors with marine-grade components specifically engineered for coastal applications. Whether you're replacing the complete wiring on Fishing Fanatic Frank's bass boat trailer that's shown signs of corrosion after years of weekly launches, installing a new system on Weekend Warrior Will's recently purchased used trailer with questionable wiring, or building Captain Chris's new trailer with professional-grade electrical components from the start, this kit delivers the reliability and completeness required for safe trailer operation. The 5-way configuration handles all standard trailer lighting functions—running lights, brake lights, turn signals, ground, and auxiliary circuits—while the included junction box and connectors simplify installation whether you're a DIY boater or professional repair shop serving Southeast Louisiana's trailer population.

At $35.00, this Harness Kit represents outstanding value for Louisiana boat trailer owners who need a complete wiring solution without the hassle of sourcing individual components separately. The kit format ensures all wiring elements are properly matched and compatible, reducing installation time and eliminating the frustration of discovering missing components mid-project. This system serves boat trailers throughout Westwego, Marrero, Harvey, and across Southeast Louisiana, where saltwater environments demand marine-grade electrical components that can withstand corrosive conditions. Applications include complete wiring system replacement on trailers with corroded harnesses, new trailer builds requiring comprehensive electrical installation, upgrading older trailers from inadequate 4-way to full 5-way systems, and maintaining spare wiring kits for commercial operations that can't afford downtime from electrical failures. The Donovan Marine quality provides consistent performance whether backing down launch ramps, traveling on Interstate 10 and Highway 90, or operating on local parish roads in Louisiana's year-round boating season.
