Each kit comes complete with everything needed to install. You will need to order 1 kit for each section your sprayer has. Along with the order you need to let us know the length of your boom.
This is optional but will be required for the injection system. At this point it will let you know if you have a partially plugged tip of completely plugged. Or even a leak at the section level. Comes complete with stand alone in cab monitor. Sold per section. "Put it on the sections you cant see". Requires at least three sections to operate properly since it compares output on each section.
Installation is simple.
