I just got a 3046R. I ordered it with power beyond with the hopes of getting a backhoe at some point. I want to add rear remotes at some point. Is there a way to add 2 rear remotes that just plug in to the rear power beyond kit I have? I know I cat just hook up to power beyond for a add g a rear 3pt hitch piston for grading. But a way to add a rear control valve off power beyond for stuff like that. Or do I need to do it a different way? A second question if I want to add a 3rd valve to the front for my loader how hard is that to do?
