The diode is required if the switch is already wired to a 12V source, such as the E-brake warning light switch. The 5V going to the 10k ohm resistor is from the 5V output in the breakout box.
Vdc0 = 5 volt output from the ADC box.
The ADC inputs can handle any 0-5 volt wideband output signal.
Find your wideband's 0-5 volt output wire and connect it directly to any of the ADC 0-3 inputs on the breakout board.
Then select the wideband in the drop down list and enable it in the software.
