CXTM 7-Way Trailer Wiring Harness — 4 ft Molded Plug, Pure Copper & Weather-Resistant Jacket

Reliable 7-way trailer wiring: a 4-foot molded plug wiring harness from CXTM built with pure copper conductors and weather-resistant insulation for dependable trailer lights and connections.

Whether you tow a camper, utility trailer or horse trailer, the CXTM 7-way trailer wiring harness provides a compact, ready-to-install link between your vehicle and trailer electrical system. This 4-foot pigtail uses standard 7-pin configuration so it swaps in with most RV and trailer sockets, and its molded plug, color-coded leads and rugged outer jacket simplify connection and long-term use.

How does this harness make trailer hookup easier?

The CXTM harness arrives ready to plug in or splice, with a molded heavy-duty plug and ergonomically shaped handle for quick connection. Color-coded wires are stripped at the ends for fast attachment to existing harnesses or for soldering and crimping.

• Molded 7-pin plug with an easy-grip handle for quick engagement
• Pre-stripped, color-coded copper leads for clear wiring identification
• Four-foot cable length gives working room without excess slack
• Compatible with standard RV/trailer 7-way sockets for interchangeability

Will this cable stand up to weather and road wear?

Yes — the wiring sheath is made from thermoplastic rubber designed to resist oil, abrasion and moisture, and the internal conductors are high-purity copper for steady electrical flow. That combination reduces corrosion and keeps lighting and braking circuits reliable in variable conditions.

• Thermoplastic rubber jacket protects against water, oil and abrasion
• Pure copper conductors for strong electrical and thermal performance
• Sealed molded plug minimizes exposure to dirt and moisture
• Durable construction suitable for regular towing use

How do I install this 7-way pigtail on my trailer or RV?

Installation is straightforward for anyone familiar with basic trailer wiring. Secure the molded plug in the vehicle socket or splice the color-coded wires into your trailer's wiring harness using crimps, solder or waterproof connectors, then test all circuits before hitting the road.

• Match standard color codes to your trailer's wiring scheme
• Use crimp connectors or solder and shrink tubing for waterproof splices
• Route and secure the 4 ft cable to avoid chafing and snags
• Perform a full light/brake test after installation

What warranty and support come with this wiring harness?

CXTM backs the harness with a one-year warranty covering manufacturing defects. If the product fails due to non-user damage within that period, CXTM offers replacement support to restore your towing setup quickly.

• One-year replacement warranty for covered defects
• Manufacturer support for installation questions and compatibility
• Clear return/replacement process for eligible issues

Who this is for: The CXTM 7-way 4-foot wiring harness is aimed at RV owners, trailer technicians and DIY boaters who need a compact, durable 7-pin connection for towing. It suits users replacing a worn pigtail, installing a new trailer socket, or adding a reliable, weatherproof link between vehicle and trailer electrical systems without custom wiring runs.
