TE 1355789-1 10-Way Female MQS Connector Plug (BMW 6909000)

The Component: Genuine TE Connectivity 1355789-1 10-way automotive unsealed female plug housing connector assembly. Micro Quadlok System (MQS) 10-position dual-row socket casing (Black / PBT-GF / Unsealed / 2x5 Grid Layout / Internal Retaining Latch System / Factory Component Cross-Ref: 1355789-1 / BMW Group OE Part Number: 61136909000 / Engineering Production Cast Stamping: 6909000).

Applications & Fitment: Designed as a high-density, low-overhead original equipment (OE) wire-to-device and inline signal connection solution for automotive sub-assemblies. Deployed heavily across modern BMW Group vehicle architectures—including BMW F-Series and G-Series passenger models, Mini, and Rolls-Royce platforms—as well as select VAG (Volkswagen Audi Group) subsystem modules.

This specific 10-pin interface is the definitive factory match for electronic turn signals, ambient cabin interior lighting controllers, steering column multi-function switch links, dashboard instrument cluster feeds, and low-current parking distance control (PDC) sensor module junctions. Positioned inside doors, roof headliners, and trunk panels, it faces repeated mechanical stress during custom retrofit additions, trim upgrades, or accident repair teardowns. It is a frequent auto-electrical replacement item because the thin integrated plastic latching beams become brittle over time and snap easily if extracted without an appropriate release tool, compromising physical mating security.
