For your BMW i3 or i3s, this used OEM Center / Third Brake Light Wiring Connector / Pigtail (part number 7304040, also replaces 7304040) provides the rear electrical connection for the brake light assembly. This genuine pigtail is removed from a donor vehicle and is ready for installation. It serves as the direct wiring interface for the third brake light, ensuring proper electrical contact. If the brake light fails or shows intermittent function, this connector may be the cause.
