Thank you for viewing. This is an Enlarge Trading power back door open kit for the Alphard and Vellfire 30 series. Normally, the power function only works for closing, but by installing this kit, it will also work for opening. This is a very helpful product for women, as the back door is heavy. It's a plug-and-play design, so even beginners can install it. There are also videos on YouTube for easy installation. I am selling this due to the sale of my vehicle.
