Don't call it a 'gator, it's a Ranger
The Ag Leader Liquid Product Control module is capable of producing a PWM (Pulse Width Modulated) output. This is a choice within the configuration setup. This output can run a variety of things directly such as hydraulic valves. It can run a 12VDC electric motor but the motor would need to be quite small so as not to overload the LPCM.
Generally a motor driver is used. with motors requiring a high current such as your pumps. It is installed between the LPCM and the motor. It is connected to the LPCM output and also directly to the vehicle battery with some heavy wires. The Output from the motor driver goes to the motor leads. The LPCM will create a low current PWM signal which instead of running the motor directly goes to the motor driver. The motor driver outputs a high current PWM output that mimics the input from the LPCM.
In other words the LPCM sets the "pace", the motor driver mimics it and actually runs the motor. Micro Trak and several other companies make these motor drivers for just such a situation.
The system would need some type of flow meter as an input to the LPCM so the system "knows" what it is putting out.
