• Connection Count: Equipped with ten distinct electrical connections, the switch accommodates all necessary signal pathways for headlamp activation, indicator integration, and diagnostic communication.
• Actuation Type: The device employs a robust lever‑actuated (basculante) mechanism, providing tactile feedback and durable operation over extensive service life.

Design and Build Quality

The Metzger 0916079 Switch features a compact, lightweight housing that conforms to the tight spatial constraints of modern vehicle dashboards. Its internal architecture is constructed from high‑strength polymers and reinforced metal contacts, ensuring resistance to vibration, temperature extremes, and electrical surges typical in automotive applications.

Compatibility Overview

This switch is engineered for seamless integration with a wide range of Volkswagen models:

• VW Passat (B3/B4)
• Polo (including the 86C and 80 variants)
• Transporter (both 4‑wheel and bus configurations)

Its standardized pin layout and connector type allow for straightforward installation, whether replacing a factory unit or upgrading an aftermarket headlight system.

Installation Guidance

1. Disconnect Power: Prior to any work, ensure the vehicle’s battery is disconnected to prevent accidental short circuits.
2. Remove Existing Switch: Carefully detach the current headlight switch by unscrewing mounting bolts and disconnecting wiring harnesses. Note the orientation of each connector for accurate reassembly.
3. Mount the Metzger 0916079: Position the new switch within the dashboard cavity, aligning it with the original mounting points. Secure using the supplied screws.
