I purchased this intending to install it on a used 20 series Vellfire, but it turned out that similar parts were already installed, so I am selling it. This is a kit that allows the door mirrors (side mirrors) to be retracted/deployed in conjunction with the door lock. You can also check the wiring diagram from the included QR code. Below is the description from the page where I purchased it: Includes a QR code for a site summarizing the connection points for each vehicle model. *Please research how to remove the switch, interior panels, and door inner panels yourself. ■ Vehicle Model: Vellfire ■ Model: ANH20W ANH25W GGH20W GGH25W ■ Year: H20.5-H26.12 (May 2008 - December 2014) ■ Notes: - 【Important Notes】 *Some vehicle models do not support the keyless unlock deployment pattern.
