In flight approximately 40 miles west of an enroute fix; First Officer (FO) saw smoke rising vertically above glare shield directly above the center of his yoke. He checked for a burning smell in the area of the yoke trim switches and map light rheostat. He could not identify the source. Moments later he saw another stream of smoke in the same area. He identified an electrical smoke smell. He noted some exposed wire on a light green wire that powers the map reading light. Though it appeared that the smoke had come from this area; we could not say so conclusively. We contacted flight control; declared an emergency; and diverted into the nearest suitable airport.
