What are "proof" wires on the ignition switch?

Well, im installing a new wiring harness and came across 2 "proof" wires on the back of the ignition switch. The shop manual doesnt say crap about it. Anyone know what they are for??

never heard of a proof wire, give me the year and the color of the wires, and I'll see what I can find in the wiring diagrams.
 
worth...

the wires are purple and the other is a red with a white tracer. I followed it on a diagram and it says one goes to the "low brake switch" and the other doesnt even have a wire on the diagram

Thanks for the help
