Brake Lamp Switch: Installation

2004 Toyota Matrix XR, FWD, StandardSECTION Installation

WARNING: This page is about a different car, the 2004 Chrysler Pacifica. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Do not reuse the original brake lamp switch. The switch can only be adjusted once. That is during initial installation of the switch. If the switch is not adjusted properly or has been removed for some service, a new switch must be installed and adjusted.

Mount and adjust the NEW brake lamp switch using the following procedure:
1. Connect the wiring connector to the switch and latch the locking tab.
2. Install the switch in its bracket by aligning the index tab on the switch with the slot in the mounting bracket (Fig 1).
3. When the switch is fully seated in its mount, rotate the switch counterclockwise approximately 30° to lock the switch into place.
4. With the brake pedal in the fully released position, move the lever on the back of the brake lamp switch from the angled non-adjusted position to the full vertical position as shown (Fig 2). This will adjust the brake lamp switch to the vehicle.
Reconnect the battery negative terminal.

• Brakes feel soft, pull hard to one side, or make grinding noises.
• The engine overheats, stalls repeatedly, or misfires under load.
• You are missing required tools, torque specs, or safe lifting equipment.
• You are not confident in the next step or safety outcome.
