Hey guys I am working on a 1250 early riser planter that is hooked to a 8220 with a 2630 display that runs the auto track in this unit. the guy wants to run clutches on this new planter and i have been told that we need the sf3 to tru count adapter cable. I, for the life of me, cant find that anywhere to order it from trimble or deere. Does anyone know what harness i am talking about? Thanks for the help
