Kits, systems, and methods for sprayers

A method of installing a on a vehicle, comprising the steps of:

• providing a vehicle having a source of electrical power and a spraying system comprising a tank for holding a liquid to be sprayed and a plurality of spaced-apart nozzle assemblies in liquid communication with the tank, each nozzle assembly comprising a check valve removably installed in a port in each respective nozzle assembly;
• providing a kit configured to be added-on to the vehicle, the kit comprising:
• a plurality of electrically-actuatable solenoids configured to be installed in the ports upon removal of the check valves and to selectably turn on and off flow of the liquid through the nozzle assemblies when the plurality of electrically-actuatable solenoids are installed in the ports;
• one or more controllers configured to be in electrical communication with the plurality of electrically-actuatable solenoids and to electrically actuate the solenoids to selectably turn on and off flow of the liquid through the nozzle assemblies when the plurality of electrically-actuatable solenoids are installed in the ports;
• a first wiring harness configured to be attached to the vehicle and to electrically connect the one or more controllers with the plurality of electrically-actuatable solenoids;
• a GPS antenna system;
• bracketry configured to attach the GPS antenna system and the one or more controllers with the vehicle;
• a second wiring harness configured to be attached to the vehicle and to electrically connect the one or more controllers and the GPS antenna system with the source of electrical power;
• and
• a mobile device configured to be in wireless communication with the GPS antenna system and the one or more controllers, to receive geographic location information from the GPS antenna system, and to process the geographic location information in view of one or more databases of information comprising map data defining spray regions and no-spray regions and vehicle data defining the locations of each of the nozzle assemblies relative to the location of the GPS antenna system when installed on the vehicle, and based thereon wirelessly communicate on and off signals to the one or more controllers to individually turn on and off flow of the liquid through each of the individual nozzle assemblies based on whether each nozzle assembly is within a spray region or a no-spray region;
• removing the check valves from the ports in the nozzle assemblies;
• installing the plurality of electrically-actuatable solenoids in the ports;
• attaching with the bracketry the GPS antenna system and the one or more controllers with the vehicle;
• connecting with the first wiring harness the one or more controllers with the plurality of electrically-actuatable solenoids;
• attaching the first wiring harness to the vehicle;
• connecting with the second wiring harness the one or more controllers and the GPS antenna system with the source of electrical power;
• attaching the second wiring harness to the vehicle;
• entering vehicle data into the one or more databases defining the locations of each of the nozzle assemblies relative to the location of the GPS antenna system when installed on the vehicle.
