Cool. I bought a more expensive one for one of my pick-ups some time ago. The one I bought has 4 different timing settings for intermittent and works on both my little ones but neither of them came with it. I would dare to guess all of the pick-ups are wired by default to accept intermittent without modifications. Its a while 1 "extra" wire from from the wiper motor. The switch has all the remaining logic.
Now I may upgrade my other one also. 200~300 was worth it 3 ish year ago. Today I am too poor for that a second time.
