I broke the connector from my trailer to the vehicle plug. I need to order a new wiring harness (connector) for the trailer. Here lies my issue. It’s a 4 pin connector, but has 6 wires. The lights are wired left and right, so two brown wires. However, I also have two ground wires (white)? Does anyone know where I can find a replacement? I didn’t even see this setup on the wesbar website. Can I splice the two ground wires together into 1?
