Review: Easy Install, everything wired as shown! - Really impressed with this NiLight 7 way harness and junction box. The quality of the coating, right back to the junction box, is 2nd to none! They included some plugs and grommets for wiring which makes waterproofing on my end more simplified. All the wiring was as shown in the diagram and super simple to add my wiring harness into the junction box. The seals appear to seat well and the box is solid once mounted to the frame. I added some NiLight 18W (low amperage draw, still super bright!)spot lamps to the reverse circuit, bumper mounted. Should make those late night pull-ins to site easierπŸ˜‰ Review: well built - good quality ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | Nilight | | Connector type | 7-pin Round | | Item dimensions L x W x H | 2.03 x 0.05 x 0.03 Meters | | Item weight | 2.76 Pounds | | Material | PVC, Rubber | | Wire diameter | 0.13 Centimeters | ## Product Details - **Brand:** Nilight - **Connector type:** 7-pin Round - **Item dimensions L x W x H:** 2.03 x 0.05 x 0.03 Meters - **Item weight:** 2.76 Pounds - **Material:** PVC, Rubber ## Images ![Nilight Heavy Duty 7 Way Inline Trailer Plug with Gang Junction Box - 8 Feet, Connector Cable Wiring Harness Weatherproof Suitable for RV Automotives Cars,2 Years Warranty - Image 1](https://m.media-amazon.com/images/I/71DWbyVmthL.jpg) ![Nilight Heavy Duty 7 Way Inline Trailer Plug with Gang Junction Box - 8 Feet, Connector Cable Wiring Harness Weatherproof Suitable for RV Automotives Cars,2 Years Warranty - Image 2](https://m.media-amazon.com/images/I/71swKSDlPAL.jpg) ![Nilight Heavy Duty 7 Way Inline Trailer Plug with Gang Junction Box - 8 Feet, Connector Cable Wiring Harness Weatherproof Suitable for RV Automotives Cars,2 Years Warranty - Image 3](https://m.media-amazon.com/images/I/719nE6wqyTL.jpg) ![Nilight Heavy Duty 7 Way Inline Trailer Plug with Gang Junction Box - 8 Feet, Connector Cable Wiring Harness Weatherproof Suitable for RV Automotives Cars,2 Years Warranty - Image 4](https://m.media-amazon.com/images/I/71jYW+LIkjL.jpg) ![Nilight Heavy Duty 7 Way Inline Trailer Plug with Gang Junction Box - 8 Feet, Connector Cable Wiring Harness Weatherproof Suitable for RV Automotives Cars,2 Years Warranty - Image 5](https://m.media-amazon.com/images/I/71mnw0P5aIL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy Install, everything wired as shown! *by R***L on 31 March 2023* Really impressed with this NiLight 7 way harness and junction box.
