  1. Joel C (verified owner)

    Very straight forward and worked as intended. Just need a simple wiring connection for my Mercedes GL350 and a 6×12 enclosed U-Haul trailer. No issues and everything worked perfectly (turn signals, running lights, brake lights).

  3. TNman (verified owner)

    Did the job. Exactly as I expected. I’m using this to power a new backup camera for my old 2005 Jeep. using the 7 pin plug I can wire the camera without tapping into my rear taillights. Piece of cake..took 5 minutes to plug and go. seems decent. should last for years. I’m using the 7 pin to power an additional light I have plugged into my trailer hitch.

    Shipped to me very fast and item is exactly as described. This company made this purchase a priority and I appreciated their service.

  5. tiff123 (verified owner)

    This adapter is perfect for what I needed. I bought a new boat and needed an adapter to a seven or five trailer connector, I wasn¡¯t sure but knew it would be one or the other. It was a seven and I was ready because of this adapter.
