The module is mounted centrally in the steering wheel rim, in the location provided by the manufacturer. Its design enables:

• proper seating in the steering wheel housing,
• a stable connection to the electrical harness,
• cooperation with the horn mechanism within the steering wheel.

By maintaining the factory shape and mounting points, the part fits well into the existing system without the need for modifications or adaptations of other elements. This is essential for both safety and the aesthetics of the cockpit finish.

Practical application and benefits of installation

Using the original steering wheel airbag module allows you to:

• restore the correct operation of the driver's safety system,
• maintain consistency with the vehicle's factory electronics,
• minimize the risk of controller errors related to part incompatibility.

Integration with other interior elements

The steering wheel airbag module works with the factory steering column, electrical harness, and equipment responsible for horn operation.
