MICTUNING 7-Way Trailer Cord 8FT with Junction Box — Heavy-Duty Waterproof, Molded Plug

MICTUNING's 7-way trailer cord with an 8-foot lead and integrated junction box is a heavy-duty, waterproof wiring solution that organizes and protects your trailer connections.

Designed for trailers, RVs, campers and towed equipment, this complete wiring assembly combines a molded 7-way plug, a flame-resistant junction box, and selectable grommets to simplify installation and improve durability. The long 8-foot PVC-jacketed cable gives you room to route wires, while solid copper conductors and a color-coded terminal layout help reduce mistakes and ensure reliable signal transfer for lights and brakes.

How does this trailer cord make wiring easier?

The junction box groups your circuits into a single, labeled hub so you can identify signals quickly and avoid tangled harnesses. The molded 7-way plug keeps the blade contacts aligned and secure for repeatable connections.

• Color-marked 7-poles for each circuit (left/right turn, brakes, reverse, tail, ground, etc.)
• Molded 100% copper blade in the plug for consistent conductivity
• 8-foot cable length for flexible routing from tow vehicle to trailer
• Clear plug diagram included to guide correct wiring

Will this unit withstand weather and road conditions?

The junction box is made from flame-retardant ABS and fitted with rubber grommets to fend off water, dust and corrosion. A supplied waterproof cover and optional open or closed grommets let you tailor sealing based on how many feed-throughs you need.

• Waterproof cover protects terminals when not in use
• 4 open and 4 close rubber grommets for selectable sealing
• Corrosion-resistant design suited to outdoor exposure

How durable and flexible is the cable for real-world use?

The cord uses a soft yet robust PVC jacket around solid copper conductors, balancing flexibility with mechanical strength for towing environments. This 8-foot lead is longer than many competitors, giving extra reach to simplify connections without splicing.

• Solid copper conductors for reliable electrical performance
• PVC housing resists abrasion while remaining pliable
• Long 8FT length avoids tight bends and allows clean routing

What comes in the box and how easy is it to install?

The kit ships complete with the 7-way plug pre-molded to the cord, the junction box, multiple grommets and a waterproof cover so you have everything to start wiring immediately. A clear plug diagram is included; basic wiring experience and common tools are all you need for a tidy installation.

• 1 x 7-way trailer plug with junction box
• 4 x open grommets and 4 x close grommets for flexible sealing
• 1 x waterproof cover and an installation diagram for guidance

Who is this for? Installers, DIYers and fleet owners who tow trailers, campers, caravans, food trucks or utility trailers and need a weatherproof, organized wiring solution will benefit most. If you want a durable, easy-to-wire assembly with longer reach than typical 4–6 ft cords and corrosion-resistant protection, this MICTUNING 7-way cord with junction box is built for those demands.
