DIY Battery B24 -> OBD2 (questions!)

Mon Oct 14, 2019 1:09 pm

Hi
I'm currently in the process of creating my own B24->OBD2 device, something that will look a bit like this https://evsenhanced.com/products/obd2-t ... y-adapter/

Now, onto my question
I've created a 2013+ B24 connector

But I need to get the wiring correct

- I will power this with external +12V
- EV-CAN H/L will go to the OBD2 port
- GND1-3 will be tied together
- I am fairly certain that I need to connect the +12V to BAT, but what about IGN? Has anyone done this before?

I figured it out, both IGN and BAT should be +12V!
