BMW part number 61121382263 is a specialized wiring set (or wiring harness/connector plug) designed for classic BMW vehicles. Depending on the specific vehicle chassis configuration, this genuine BMW adapter harness serves two primary functions:
- ASC+T Oil Carrier Sensor Connector: In many configurations (such as the E31 8 Series), it acts as the wiring subset for the oil carrier associated with the ASC+T (Automatic Stability Control + Traction) system.
- Alarm Siren/Sensor Adapter: It is also widely used by enthusiasts and mechanics as the factory connector plug to retro-fit or replace an OEM anti-theft alarm system siren or hood/radio sensor.
