OBDII Pin Out info

Can anyone tell me the OBDII plug pin-out?
I am looking for battery charge info, is this available via the OBDII port, or do i need to connect to the Gateway Module?

I apologise if this is already here somewhere, i have looked but i couldn’t find it.

This is the cable most people use to connect OVMS to the OBDII port.


Great, thanks… I will give that a try
