Sea Sense Tailer Wire Harness 25'

The Sea Sense Tailer Wire Harness 25' is a marine-grade electrical connector assembly designed to link your boat's electrical system to a trailer. If you're towing behind a vehicle and need reliable power delivery for trailer lights, this harness simplifies the job with factory-color-coded tinned wires that resist corrosion in salt and freshwater environments. The 4-pole vehicle-side connector matches standard automotive tow configurations, and frame clips keep the harness securely mounted during transit.

Marine electrical connections demand durability—corrosion and moisture are constant threats on the water. Sea Sense tinned copper construction handles both better than bare copper, especially if you're regularly trailering in coastal conditions or freshwater lakes. The 25-foot length gives you reach from the tow vehicle's connector back to stern lights and other trailer-mounted equipment, with enough slack for routing around the frame and fenders.

This is a straightforward electrical harness, not a complete ready-to-use kit—you'll need basic understanding of your vehicle's tow wiring and boat trailer light setup, or be comfortable working with an installer. Color-coded wires make the job cleaner, and the included frame clips eliminate improvised mounting solutions that compromise safety or longevity.
