To remove the brake switch in vehicles from 2005 and earlier, start by removing the driver's side under-dash cover. Then, locate the switch at the top of the brake pedal bracket and twist it counterclockwise to remove it from the bracket. Disconnect the electrical connector from the switch. For installation, connect the electrical connectors to the switch and push the new switch into the clip until the switch plunger is fully depressed. Rotate the switch clockwise until it locks into position and no further adjustment is needed. Ensure that the brake lights are functioning properly. The rest of the installation process is the reverse of the removal. However, for vehicles from 2006 and later, a Brake Pedal Position (BPP) sensor is used, which requires a calibration procedure performed by a dealership service department or professional repair facility equipped for the necessary programming.
