Features
- DOUBLE PRONG TRAILER PLUG: Cheemuii 7 pin trailer plug uses the premium copper double prong to replace the poor single prong, and the outer wrap is made of weatherproof and durable material to ensure a longer service life
- JUNCTION BOX: The junction box is equipped with 7 color-coded terminals and wires, which can easily identify the corresponding functions of the wires and facilitate wiring. Strong junction boxes are waterproof and dust resistant to increase the service life of trailer cords
- COPPER POWER CORD: The 7 way trailer wire is made of high-quality copper and has a long service life. And has excellent electrical and thermal conductivity, to ensure the normal use of car lights in the process of driving (such as turn signal and brake lights, etc.)
- DETAILED WIRING INSTRUCTION: CheeMuii trailer cords use 7 color-coded wires, and the color code adopted is suitable for most RV trailer wiring standards, but as there are some differences between trailer manufacturers, we have updated the detailed instructions, please read them carefully before use. Please refer to the wiring instructions and connect cables according to the color and function of the wires to avoid errors
- WIDE APPLICATION: Suitable for trailers, RVs, campers, caravans, food vans and other towed vehicles. Perfectly connected taillights, brake lights, reverse lights, turn signals and auxiliary power

My husband ordered this for a cattle trailer and he absolutely loves it. Has ordered another. Easy to install and has everything you need. The quality is good and the size of the wires makes it easy to work with. Great product.

Just installed, but was fairly easy. It comes with a cross reference but it also has the terminals labeled. I just matched the colors on my trailer to the labeled terminal function. Worked perfect and didn't have to mess around with matching wires. Terminal box does not appear waterproof, so its may need ether silicone all around to seal it up or just put terminal grease over everything. For the price I think it was a decent deal. 7 pin connector seemed OK quality. I believe the wires were copper as well.

Size: 7 PIN BOX
This review is for the junction box ONLY, no wiring kit was purchased. Also this review is only from the standpoint of finding a junction box to use for the installation of emergency LED lights and not for trailer use. This box was exactly what I needed, a box with multiple access options, one that’s beefy and has a color coding. This really helped me to install and organize multiple harnesses that I linked in this box, with six positive posts, and I also modified the box to use the seventh post for grounding each of the wire harnesses. The output cord was a six pole 18 gauge wire that went through the firewall, being wired into a 12-gang switch panel. I’ll add photos and shoot some footage of how I wired. The box has plenty of interior space and functions quite well for my needs I’ll add photos and a video and update as things happen.

This works great. Easy to hook up. The 8 ft wire feels little short so better get the 15ft option. It is strong and durable. The color of the wire and the assigned role are a bit different from what i had but not so much of a problem. It show the color and what wire do what so i love it.

Saved the Day! Pinched the cable on our Camper while backing in, and need a replacement to drive home safely. Had this shipped to a friend who was coming camping with us the next day. Easy install! Works as expected!

The quality of the product was very good. The junction box connections were clearly all marked and color coded and the documentation was great. I tore the floor out of my trailer, removed all the old wiring, and did the install with all new wiring and connections. I did not have reverse lights but I do have electric brakes. I would highly recommend this product!
