To run task controller, or for any autoswath, I think you will need the 6 switch switchbox from DJ (if you keep that functionality on the DJ side).  I don't remember the part number, but I think it is listed in the ag leader knowledgebase.  The planter I converted, we switched to the ag leader ccm.  I think we still needed that 3 switch switchbox for something else on the planter though.
