1971 Road Runner cornering light switch??

After digging thru a couple different schematics, I finally found out what this 3 wire plug is for, but I have never heard of it before! Ever heard of the cornering light switch? What is it and where would I find it? Critical to wire it up or just let it be? I found no such mating connector in the "original" harness. I should add that this plug is coming out of the column in the same area as the ign switch and turn signal wiring.

Cornering lights were standard on 1971 Imperials & optional on Chrysler models - http://www.hamtramck-historical.com...aBook/1971/71_Chrysler_Features_0014.jpg

Thanks! Guess I won't worry about it then!
