The stalk assembly is designed to work with factory electrical connectors, which facilitates installation and reduces the risk of connection errors.

The layout of contacts and signal paths is adapted to the operating logic of the turn signal and cruise control systems in this model, so that after proper installation, it is possible to maintain the full functionality of factory solutions without the need for additional wiring modifications.
