Installation Notes and Tips
Verify connector style, terminal type, and vehicle application before installation. This brake light switch uses a male connector with two male blade terminals, so matching the existing harness and switch mounting style is important for proper operation. Confirm the brake pedal switch adjustment after installation so the stop lamps activate at the correct pedal position.
