Can't give you any specifics on switching the controls, but something to be aware of from my reading on the BT602. Kubota added some damping on some of the cylinder functions to slow movement down at the end of the stroke. I'm thinking they put this on the swing cylinder only, but not sure. I do know my swing function is much faster than any other function and is real touchy. Anyway, if you reverse the controls, you might need to take that into account, assuming you want to move the swing to the other stick (not familiar with CAT controls.)
