Features

  • 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 cord 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.)
  • BREAKAWAY SWITCH: This 12 V trailer breakaway switch provides safer traction by connecting the trailer's breakaway battery and trailer brake. If the trailer is disconnected while being towed, the cable will release and the brakes will be activated
  • 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 APPLIATION: Suitable for trailers, RVs, campers, caravans, food vans and other towed vehicles. Perfectly connected taillights, brake lights, reverse lights, turn signals and auxiliary power

  • Simple installation
Size: 8 FT KIT
Very easy to install. Terminals are well built and easy to add crimp connectors to. I drilled small holes in the bottom of the plastic enclosure just in case water leaks in it can drain out without shorting out any of the wires.

  • Had to do a little research on our wiring but worked perfect!
Size: 8 ft
After figuring out what my wire colors were for my 5th wheel camper this was a breeze to install and saved me lots of money! Took a little extra work on my end but in the end I saved so much money!

  • Great value, swapped from 6 round trailer
Size: 8 ft
Swapped form 6 round to this 7 way connector. Took some googling to find the right color conventions, but after figuring that out wiring up was perfect. Heavy duty for the price.

  • Workes as advertised!
Size: 8 FT KIT
I had no issues with this product. All of the pin connections were correct. Looks like 100% copper wires to me. The 7 pin connector securely attached to my truck (2023 RAM 1500).
