I was installing a headlight switch last night and all went very well.

But.....as I was looking under the dash i noticed a knob that i have never seen before. It is only accessible when the the lower bolster is loosened as i did to remove the headlight switch. The previous owner of the car did some weird things so i am not sure if this is an original feature. (he removed the kick down switch,????Why would anyone do that?)

Any help in figuring this out would be appreciated. I didn't touch it, but i might to see if it does anything

Thanks
