F Connector Reverse

Can anyone explain/ guide regarding F1 F3 and F5, Can i connect OBD or Canbus, How can i do its settings.

adeebulrehman The C connector is for CANBUS communication, the F connector is not, the annotation is wrong

dudu-lai It work like a charm, I connected OBD2 pin no 6 and 14 directly to F1 and F3.
