And this is what our OBD connector looks like from the back. As you can see, there is a factory numbering of contacts.

 

 

 

 

 

 

1 – CAN HI
2 – CAN LOW
3 – GND
4 – K-Line
5 – ACC
6 – Analog OUT

The voltage range at the analog output is 0-3 volts. Thus, you can connect a conventional voltmeter with a scale of 3 volts. When using a device for a lower voltage, you will have to calculate the divider.
