Charlie,
The Brown lead is connected to a positive (+12 V) output of the PD through a 20 amp breaker. The Blue lead is connected to the associated negative output of the PD. The White Lead and the Black Lead should be connected to two different digital inputs on the Digital Side Car depending on how you choose to use the device. If you choose to use a PWM cable to connect to the DSC, please cut the red wire as close to the PWM connector as you can, pull back the red wire back at least one inch and cut off the end. You may then cutoff the other end of the PWM cable, connect the black wire of the PWM to the negative wiring (Blue & Black) of the power and sensor. The white or signal wire in your PWM cable can then be connected to the White or Black lead on the sensor. The resistor loads shown in the drawing are not needed as they are provided internal to the digital inputs on the Digital Side Car. You may connect several sensors in parallel to share power supply connections only. All connections need to be insulated and soldering is recommended to keep wiring together.
The loads shown on the Rockwell drawing are indicative of relays or solenoids that are part of a control system and operate at the same voltage as the power supply, in this case 12 volts.
