RVGUARD 7-Way 16ft Trailer Cord Kit with Waterproof 7-Gang Junction Box, 12V Breakaway Switch

If you tow an RV, trailer, camper, food van or utility trailer, messy or unreliable wiring is a common headache. This RVGUARD kit bundles a long 7-way cord with clearly color-coded conductors, a rugged junction box to protect splices from the elements, and a breakaway switch to help activate trailer brakes in an emergency. Built with 100% copper conductors and flexible PVC insulation, the components are designed to remain flexible in cold weather while resisting corrosion and moisture.

How does this kit simplify trailer wiring?

The kit brings together the main items you need to create a neat, single-point wiring hub between tow vehicle and trailer. Color-coded wires reduce guesswork during splicing and make future repairs or diagnostics faster. The included plug holder keeps the vehicle-side connector secure when not in use.

• 16-foot 7-way cord lets you position junction box conveniently on most trailers.
• Seven color-coded wires match standard trailer circuits for tail, brake, reverse, turn signals and auxiliary power.
• Plug holder secures the vehicle connector and prevents dangling strain on the cord.

Will the junction box protect my connections in wet weather?

The 7-gang junction box is designed to seal electrical splices from dust and moisture so connections remain reliable in rain, road spray and winter conditions. Its waterproof housing keeps corrosion risk low and extends the working life of your wiring. Use proper grommets and sealants where cables enter for best protection.

• Water-resistant enclosure shields terminals from environmental exposure.
• Plenty of room inside for tidy splicing and secure connectors.
• Mountable design fits common trailer frames and crossmembers.

What safety features does the breakaway switch provide?

The included 12V breakaway switch is intended to engage the trailer brakes automatically if the trailer becomes disconnected from the tow vehicle, helping reduce runaway risk. It connects to the trailer’s breakaway battery and brake circuit, and is mounted so the pull pin will activate under sudden separation. Always test the switch and battery before heading out.

• 12V breakaway switch designed to activate trailer brakes when pin is pulled.
• Easy to mount near the coupler for correct operation in an emergency.
• Includes wiring provisions to tie into your trailer’s breakaway battery and brake actuator.

How durable and flexible is the cord for different towing conditions?

The cord uses full copper conductors with a flexible, abrasion-resistant PVC jacket that stays pliable across temperature ranges and resists road chemicals. The molded 7-way plug is heavy-duty to withstand repeated connection cycles and rough handling. These materials help minimize voltage drop and maintain consistent signal and power delivery.

• 100% copper wire for reliable conductivity and lower resistance.
• Soft, rugged PVC jacket resists cracking and abrasion on rough roads.
• Molded copper-blade plug provides a secure, weatherproof connection to the tow vehicle.

Who is this for? The RVGUARD 7 Way 16 Foot Trailer Cord Kit is made for RV owners, trailer fleet operators, DIY trailer builders and anyone who wants a durable, organized wiring solution. It's especially useful for those needing a longer cord run, a protected wiring junction, and a simple way to add a breakaway safety circuit. If you value weather resistance, clear wire identification and a ready-to-install kit that reduces clutter and improves tow reliability, this package is a practical fit. Always review your trailer's wiring diagram and local regulations before installation, and consult a professional if you are unsure about electrical or brake system work.
