Wiring a switch to an ADC input.

  1. 2 prong switch (clutch switch/cruise switch or toggle)
  2. 1k ohm 1/8 watt resistor
  3. 1 fA Diode

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.
