I don't have access to enough piles of parts to properly categorize all the years/ changes in wipers. My standard answer is go to Passion which has a lot of info buried on their website, Welcome to Passion4Mopars - Because Mopars Are My Passion Too
And then go to MyMopar and download some shop manuals. Both the wiring diagram and the text section in the electrical chapters have useful info on the changes in variable, 2 or 3 speed wiper systems
