The 1966 Ford Mustang came equipped with a single mechanically operated brake light switch. In this design, as the brake pedal is depressed, a metal spring inside the switch compresses, and an electronic signal is sent to the brake lights. The design of the switch is fairly basic, but the switch can wear out, and the spring can rust over time. Regardless whether the Mustang came equipped with manual or power brakes, all models were equipped with identical switches; changing these switches usually takes only a few minutes and can be done by the average DIY mechanic.
Tools Used: Needle-nose pliers

Slide the replacement switch onto its post, followed by the nylon washer.
