Walter L,
Thank you, Sir! I do have rear remotes and connecting to those is one of the options I've been strongly considering. From what I've seen online, it looks less complicated, and less expensive as you said. For my tractor, I'd have to extend and change the and angle of the lever that operates the rear remotes, so I don't have to reach back to access it. That's totally doable. Greatly appreciate you sharing your ideas!
