I really haven't thought about it until now, I guess my grapple control is also the rear control. I thought I had asked for some mid scv control, but I guess that's not the case. Anyway, if you get a diverter, please post a picture and explain how it works (maybe the part number too). I do have a wagon that could uses the rear hydraulics. It seems a toggle switch controlled unit would work, if there is such a thing (as there seems to be slots for switches available on the panel).
