Technical Connectors identification on the Body Control Unit

[Panda Bear]

Hi to you all. I have a wiring diagram which appear to identify connectors alphabetically. This does not match the identification on the body control unit.
I'm trying to diagnose/fix non-working LHS sidelights (blips on for a second then turn off when turned on and non-working license plate lights).
Appreciate any help you can offer

Have you checked for dirty bulb contacts and earth wiring contacts?
