Actually that harness from Ag Express completely bypasses the Deere CAN system. It has its own ISO plug to go directly to the planter.
My suggestion is to run the Serial cable for GPS to the 700 into that harness from Ag Express instead of the back of the 700. Goes to the same place but for me I have better luck into the harness. Just my 2 cents
