It's for wiring your porch light into the step light or installing a dedicated switch for the step light (not the steps switch) that supplies 12 volts to the purple wire. It's typically not done so the wire is just stowed. It provides an input to the step control unit that will illuminate the step light continuously whenever the porch light or dedicated step light switch is on (fused 12 volt input to the purple wire). The step light normally illuminates only for about 5 minutes otherwise.
