The ignition switch with start/stop button is designed as an OEM part, which means it fits the factory control panel and wiring harness in the Mini cabin. The design includes appropriate connectors and mounting points, facilitating installation in place of the original component without the need for electrical modifications. This maintains the visual consistency of the cockpit and the proper operation of related electronic systems.
