Installation Guide

The installation process for the Bosch 0986345115 Stop‑Lamp Switch is straightforward and can be completed by a skilled technician or an experienced DIY enthusiast. Follow these steps to ensure proper integration:

1. Disconnect the Vehicle Battery: Prior to any work, remove the negative battery terminal to prevent accidental short circuits.
2. Locate the Existing Switch: Identify the current brake light switch or the area where the new unit will be mounted. This is typically near the brake pedal assembly.
3. Remove Old Components: Unscrew and detach any existing switch or mounting hardware, taking care to note cable routing for reassembly.
4. Mount the New Switch: Position the Bosch unit on the designated bracket. Secure it with screws, ensuring that the housing aligns correctly with the vehicle’s chassis.
5. Connect Wiring: Attach the two‑terminal plug to the brake light circuit. Verify polarity if applicable and use proper crimping or soldering techniques for a reliable connection.
6. Test Functionality: Reconnect the battery, depress the brake pedal, and observe whether the rear stop lights illuminate promptly. Check for any flickering or delayed response.
7. Final Checks: Inspect all connections for tightness, ensure no exposed wires are in contact with moving parts, and confirm that the switch remains firmly mounted during vehicle operation.

Compatibility Overview

The Bosch 0986345115 is engineered to fit a broad spectrum of vehicles. While it is not limited to any single brand, its design accommodates:

• Passenger Cars: Compact sedans and hatchbacks that require standard brake light circuits.
