### ⭐⭐⭐⭐⭐ Great product
*by C***R on June 27, 2025*

Works great. Easy installation. Great price

### ⭐⭐⭐⭐⭐ High quality, great price
*by E***  on April 15, 2025*

used it to wire up my overland trailer build. I loved that it came with the wire hose to keep everything tidy and clean. the wires are high quality and the plugs are good too. It was plenty long for my needs and it worked very well.

### ⭐⭐⭐⭐⭐ Excellent quality, protective braided coating Harbor Freight trailer
*by R***T on July 3, 2025*

Why did you pick this product vs others?:I love that this kit has the braided protective cover on the wiring! I have gone thorough so many wiring kits for my trailer in the past and they haven't lasted long. The thick coating allows for tight zip tying to the frame and protects the wiring from the elements. Great quality and my trailer is working 100% again.
