Brake Input – Black Wire with White Stripe
The brake input should connect to a positive 12 volt switched power activated when the brake pedal is
depressed. When the brakes are pressed, the wire should get 12 volts. Depending on the installation
this wire may or may not be used. This is a useful input for an administrator to see if an officer was
pressing the brake before a crash.
