Review: Weathered the storms. - This is a well made product done right. The box has holes inside that you can use self-tapping screws to place on the side of the frame. Then there are plenty of rubber grommets to fit to your wires exiting the box. This is the happiest I have been with a trailer wire system ever. Made requiring a snap. Clear color coding and even came with a plug holder for when the trailer is parked. After 2386 miles through two “hazards on” storms in Illinois on Rt 66 and in Oklahoma with tornado warnings on I-40, dust, heat and flooding on roadsides, they are doing great!
Review: Great product! - Well made, pretty straightforward install on our 2014 Grand Design Solitude 369 RL.

## 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
- 7 WAY POWER CORD: The 7-way trailer cord 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
