Here's why:
* Manual Transmissions: The backup lights on a manual transmission car are typically activated by a reverse light switch located on the transmission itself.
* Location: The reverse light switch is usually mounted on the side of the transmission, near the reverse gear. It's a small electrical switch that is activated when the transmission is shifted into reverse.
Important Note: A 3-speed transmission in a 1966 Mustang is a manual transmission. There is no separate switch or button for backup lights. The reverse light switch is integrated into the transmission.
