Installation Notes and Tips

Verify connector style, terminal count, and steering-column configuration before installation. This switch is listed for vehicles with tilt steering wheel, auto headlights, and fog light equipment on many applications, including select Toyota Tundra and Lexus ES350, IS250, GS350, RX350, and LX570 models.
