The construction is designed to work with the factory door panel, guides, and window control elements, in accordance with the Window regulators and motors category.

The placement on the vehicle in the rear right part of the body allows for direct replacement of the damaged component without the need for door modifications. Properly selected mounting points and electrical connectors help maintain tightness, correct lock operation, and smooth cooperation with other door components.
