19 The one set of wires that make this switch different than others is the illumination wires. These can be wired to come on with either the ignition or the headlights. Since this is a hard top car Lucky decided to wire them to the ignition so if the key is on the lights are on. Once the custom console is constructed, the switch can simply be dropped into place. That completes the install on this car and we can report the windows function as if the factory built it that way. The glass comes up smooth and the motors are nice and quiet.
