It may change wire color at the connector, you will have to check and verify that because i don't have a 2014 to look at. But it will be a gray wire going into the feedthrough and on to the CN101 connector pin 5 on the top board of your picture.
This was drawn up in the schematics post #3 of the OBC thread.
Are you having errors, or what is your project?

The functions and the wiring harness may be the same or very close such that there is some interchange possible, but it is not clear to me.
The EV-ECU is the master controller for the whole car and it is tied to a specific VIN, so any replacement needs the programming of the MUT-3 tool to enter the proper value. But it also holds the DTCs and if you are able to read those, then it would indicate some functionality still exists. So maybe the internal damage is limited and repairable?
Let me know what you need for component identification and circuit tracing for the OBC and i'll help you there; i don't have a 2014 EV-ECU, but if you post hi-res pictures we might be able to do some good there too.
