I know this is a really minor complaint but it is one of the very few things left I am interested in possibly changing on my HDJ81. Right now, it has one intermittent wiper speed (front wipers), and it's pretty quick. Almost every modern vehicle has an adjustable intermittent wiper if not at least 2 speeds. Has anyone else made the change to a variable intermittent wiper switch? If so, how and what fits?
