This year we want to use the McMaster-Carr high flow double solenoids part no. 6124K514 found at
http://www.mcmaster.com/#catalog/120/1007/=qa3jr8. In the past, our team has used solenoids that require only two pins of electronic input. The electronic input on these particular solenoids is provided by a DIN connector and requires three pins: a hot, neutral, and ground. How/Where would we connect the three pins to the robot? How is it different from connecting the two pin solenoid electrical input?
