On my '79 Scout II I have a switch to the right of the wiper switch that I believe to be after-market. It seems to be a three position switch, (up, center, down). I haven't been able to trace it yet. I know it's a long-shot question, but does anyone have any idea what it might have been for? It doesn't seem to do anything now. I think a prior owner of the vehicle may have towed with the vehicle. I'm hoping to use that switch position for a set of fog lights. Any insight appreciated. Thank you.
