Review on 🚗 25ft Male & 4ft Female 4 Pin Flat Trailer Wiring Harness Kit [Wishbone-Style] [SAE J1128 Rated] [18 AWG Color Coded Wires] - 4 Way Flat 5 Wire Harness For Utility and Boat Trailer Lights Kits by William Mathis

This harness works but I had two problems with it: 1) I wanted to rewire my trailer so the ground wires go all the way to the rear lights, not grounded through the trailer chassis. Grounding through the trailer chassis introduces problems like bad connections due to corrosion etc so I wanted to rewire my trailer with ground wires going to each of the taillights. . This harness has a short (about 2 feet long) white ground wire that is not suitable for this. I had to extend my own cable. The product description was unclear on this and I thought I had the full 25 foot length in all wires. 2) I wanted a trailer wiring harness with wires fused together so I didn't have to use 100 zip ties. Some trailer wiring harnesses are designed so that the wires are connected together in the form of a ribbon cable, making for a tidy installation. This harness consists of loose wires that simply connect to the connector. So. During the installation I had to use 100 cable ties. The product description was unclear on this and I figured I was getting a fused harness.
