Have a 3330 sprayer and have had to replace the manual override sensor for the autosteer (trimble) several times over the years. One was faulty out of the box (covered under warranty). The latest price of $900 is insane. Part# is 47626975. Latest one has square edges instead of being round, so maybe it is a different and hopefully better supplier.
Thought I found a replacement in an old thread I had bookmarked, but it was for Raven steering.
Looking aftermarket override sensor for Case/trimble autosteer
