On a 1999 Harley-Davidson Fat Boy, the speed sensor is typically located on the transmission. Specifically, it is mounted on the left side of the transmission case, near the output shaft. The sensor is responsible for detecting the rotational speed and sending this information to the speedometer. To access it, you may need to remove the left side cover or other components depending on your specific setup.
