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 Richard Cunningham

Trailer wiring replacement went great. The problem occurred when I tried to connect it to my Highlander. The rubber coating on the (white) ground wire was larger than the old connector, making it difficult to insert the trailer connector into the vehicle connector. I had to shave off the rubber on both connectors to make it work. The old connector I replaced fits correctly. I expected it to be a universal fit.
