## Description

Product description

Review: Very nice! Keeps wiring organized. - This is my first trailer project and I appreciated how the wiring installation was clear. After a trial-and-error learning curve on my part, all my lights work and the brakes as well. First picture is about halfway through the wiring process. In the end, I attached a solid ground to the trailer and white post in the junction box, and used split wire loom tubing to cover the wire. It came out looking professional in the end.
Review: 7 way plug - Very clean setup secure cap is snug good product

## 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
