put row clutches on older kinze planter. using the kinze monitor. 2630 screen 3000 sf1 globe. ISO to JD rate controller. Do I hook the harness from the implement switch mounted on planter to the ISO rate (section) controller harness or to the in-cab harness to the 2630? voltage at cab harness connection is 2.5v. Voltage at ISO rate controller harness connector is 4.5 volts, if that matters. Want to be able to "paint" the field as I plant.
