As you know if the switch is tightened up too far from the point of pedal contact it'll stay permanently on just like when you step on the pedal. Not sure what's up the other way but I'm sure a visual will tell you. The bracket is slotted so you can position it so the round nub is compressed (no continuity/brake lite off) with your foot off of the pedal at rest and you want it where you move the pedal a very slight bit for continuity. The pink wire is the hot wire (just remember "hot pink") so dont inadvertently ground it & waste a fuse.
