71 Charger turn signal switch

For the life of me I cant figure out what the 3-wire connector is for on this turn signal switch. I cant find a coresponding connector under the dash and I have two different wiring diagrams and neither show that wire connector coming off the steering column.
Its from a 71 Charger ralley dash/console automatic car.

They are for C-body cornering lights. The Mopar replacement switches seem to all have them. Have found them in several B and E bodies.

Thanks. So I don't need to worry about it.
