I am looking to add section control to my 4000 navigator. I have an HC5500 controller, and a Pro 700 Monitor(CaseIH). The sprayer is not ISO BUS wired, and doesn't have a JobCom Box. Is it possible to accomplish section control with this sprayer? What will I need to add, component-wise, to do it? If it's possible, then what will it cost, (ballpark figure)?
