Deluwire 15FT 7-Way Coiled Trailer Cord — Heavy-Duty Weatherproof ABS 7-Pin Cable for Trucks & Trailers

Deluwire 15FT 7-Way Coiled Trailer Cord is a heavy-duty, weatherproof ABS electrical cable that delivers standard 7-pin trailer power and signal connections for semi-trailers, trucks, and tractors.

This coiled 15-foot, 7-way cable provides a compact, durable connection for trailer lighting and auxiliary circuits. Built to SAE standards, the cord combines multi-gauge copper conductors with corrosion-resistant hardware and protective springs so it stays flexible, resists outdoor damage, and maintains reliable electrical contact under real-world towing conditions.

How does this cable keep trailer lights and signals reliable?

The Deluwire 7-way extension uses premium copper in mixed gauges (4/12 + 2/10 + 1/8) to carry power and signal loads with low resistance, helping lights and brakes operate as intended. Brass terminals and a zinc die-cast plug resist corrosion and maintain firm contact even with repeated connect/disconnect cycles.

• Premium copper conductors sized for lighting and auxiliary circuits
• Rust-proof brass fittings for consistent electrical connection
• Zinc die-cast 7-pin plug built to SAE J560 testing standards
• Meets SAE J2394 safety and performance criteria

Will the coil stay flexible and intact in extreme weather?

This trailer cord maintains flexibility down to -85°F (-65°C) and resists UV, diesel, and general outdoor degradation. A double-layer reinforced handle and stainless-steel spring guards at both ends protect the cable from stress where it usually bends and stretches.

• High-elasticity stainless-steel spring guards at both ends
• Waterproof and UV-resistant jacket for long outdoor life
• Diesel-corrosion resistant materials used throughout
• Double-layer reinforced handle for strain resistance

How durable is the plug and why does that matter?

The zinc die-cast 7-pin plug resists deformation and breakage compared with cheaper plastic plugs, so the plug face and pins retain their shape and alignment. That durability reduces electrical faults and the need for frequent replacements in heavy-use towing scenarios.

• Zinc die-cast housing for impact resistance
• Plug construction meets SAE J560 test requirements
• Secure grip design eases connecting and disconnecting
• Weatherproof plug materials for long-term use outdoors

How easy is it to install and match to my trailer or truck?

The 15-foot coiled length expands to give reach while staying compact when not in use, reducing drag and snag risk behind the tractor. The 7-way standard configuration fits the vast majority of semi-trailers, trucks, and agricultural equipment, so installation is typically plug-and-play.

• 15-foot coiled design extends as needed and retracts for storage
• Standard 7-way pinout compatible with common trailer systems
• Plug-and-play hookup without special adapters in most cases
• Clear, rugged handle for quick connections in the field

Who is this for? The Deluwire 15FT 7-Way Coiled Trailer Cord is aimed at professional drivers, fleet operators, and equipment owners who need a dependable, weather-resistant 7-pin connection for trailers, refrigerated units, and heavy equipment. If you tow frequently, operate in extreme climates, or want a long-lasting replacement for worn trailer wiring, this cable delivers a robust, standards-compliant option backed by Deluwire support.
