It appears to be pin 5 on the blue connector. Only on the high cluster of course

All you need is a MID or Nav screen. To change/set/reset/start/stop any of the OBC functions/features...is all done using the MID or Nav screen.

Are you asking because the MID or Nav screen has been removed/replaced by and aftermarket audio unit? If so, you also removed the component that has the means to control your OBC.

For example, if you have a high instrument cluster...you need a high MID or Nav screen and you can change the OBC from gallons/miles to liters/kilometers (see button circled in green below). You use the MID or Nav screen also to set the clock and reset the AVG MPG & MPH calculations:

As you can see in the info below...the MID and Nav screen are simple input devices that are designed to control multiple components/systems that sends data to them:
