MICTUNING 7-Way Trailer Cord with Junction Box 8FT — Heavy-Duty Waterproof, Color-Coded Wiring

This heavy-duty wiring assembly is built to simplify trailer electrical work: a molded 7-way copper blade plugs into your vehicle, a color-coded junction box sorts and secures each circuit, and an extra-long 8-foot cable gives you flexibility to route wiring across most tow vehicles and trailer frames. The housing uses flame-resistant ABS and rugged PVC insulation for weather resistance and long life, while included grommets and a cover help keep moisture and dust out of the connection points.

How does this kit make trailer wiring easier?

The kit centralizes multiple circuits into one neat junction box so you don’t have to run separate wires for each function. Color-coded terminals match standard trailer wiring, reducing guesswork and installation time.

• Molded 7-way 100% copper blade for secure electrical contact
• Color-marked 7-pole junction block to identify each circuit
• 8-foot cord lets you position the box where it’s most convenient
• Clear plug diagram included to guide correct connections

Is the junction box weatherproof and corrosion-resistant?

Yes — the junction box uses flameproof ABS and includes rubber grommets and a removable waterproof cover to protect terminals from water and grime. Those features help prevent corrosion and keep connections reliable in wet or salty conditions.

• 4 open and 4 close fitted rubber grommets for tailored sealing
• Waterproof cover protects unused or exposed terminals
• PVC-sheathed cable resists abrasion and environmental wear
• Materials chosen for durability around road spray and salt

Will this cord work for my RV, trailer, or camper?

The assembly is designed for a wide range of tow applications including RVs, travel trailers, campers, caravans, food trucks and other towed equipment that use the standard 7-way connector. Its heavy gauge copper conductors and sturdy plug construction are intended for repeated connection cycles and towing conditions.

• Suitable for turn signals, brake lights, tail lights, reverse lamps and auxiliary power
• Robust plug molded to resist bending and contact wear
• 8FT length provides extra reach compared with common 4–6FT cords
• Ideal for retrofitting or replacing worn factory wiring

What components come in the package and how do I install them?

The package includes the pre-molded 7-way plug with 8-foot cord, a junction box, four open and four closed grommets and a removable waterproof cover. Installation involves routing the cable, mounting the box, matching wires to the color-coded terminals and sealing unused openings with the supplied grommets.

• 1 x 7-way trailer plug with 8FT cable and molded copper blade
• 1 x flameproof ABS junction box with color-marked 7 poles
• 4 open + 4 close rubber grommets and 1 waterproof cover included
