  5. Mount and adjust the NEW stop lamp switch using the following procedure:
    • Insert the plunger end of the switch in the mounting bracket by aligning the index tab on the switch with the slot in the mounting bracket.

    • With the brake pedal in the fully released position, move the lever on the back of the stop lamp switch from the non-adjusted angle position to the full vertical position. This will permanently adjust the switch to the vehicle.
