My sprayer has a double solenoid on it. One to control the pump, the other controls the Boom. I currently have the LP68195 sprayer harness but its just one rocker switch and harness hardware. Has one on on here figured out a way to incorporate a second switch to control the sprayer boom. I been looking on the John Deere parts pages and I do not believe there are any options here. It seems like it should be possible as these 835r's seem to have all sorts of wiring options. Thanks for the help in advance.
