Key Features:

• OEM Connectors: Utilizes vehicle-specific "plug-and-play" connectors that match BMW's factory wiring for a secure installation without cutting or splicing.
• Trailer Stability Program (TSP) Support: Fully integrates with your BMW’s safety systems to help correct trailer sway by automatically adjusting brakes and engine power when a trailer is detected.
• CAN Bus Integration: Communicates directly with the vehicle's data network to manage complex towing functions and ensure your BMW's warranty remains protected.
• Automatic Activation: Designed with "Automatic Programming" to activate towing features within the vehicle's computer systems seamlessly.
• Full LED Compatibility: Works perfectly with trailers and bike carriers equipped with LED lights, preventing dashboard error messages or hyper-flashing.
• Smart Sensor Management: Automatically deactivates rear parking sensors and disconnects rear fog lights on the vehicle while towing to prevent interference.
• Power Supply Included: This 13-pin kit includes a steady plus (Pin 9) power supply as standard. (Note: Extension kit 764159 is required for ignition-switched power/Pin 10 battery charging).

Note: This kit is suitable for the BMW X3 G01 (08/2017-on), X4 G02 (04/2018-on), and iX3 G08 (09/2020-on). It is the recommended replacement for the older BR-703524 part number.

Please Note: Towbar wiring is a safety-critical item. Due to the high complexity of modern BMW electrical systems and CAN Bus networks, we strongly recommend installation by a professional towbar fitter or vehicle accessory workshop.
