I wonder if you could just swap the leads..
Assuming the push pull have the same switch type setup, it may work. I don't think Ducati is producing a strain gauge shifter yet
Is it a 3 wire connection?
Edit: just saw a picture it is 3 wire.. It just may work
Someone made a post a while ago about grinding the gear selector arm a little bit in order to avoid the rod hitting the bracket? Anyone knows who that was?
