Reverse Lights no working 2004 VY S2 Cross8 Creman

[Highlander19]

No reverse lights, Bulbs are all good, Holden manual for relay fuse shows its in the engine bay fuse box but on the box diagram there is no reference for the relay or where the book shows it should be. After market Reverse camera still works, so would that mean the reverse switch is still working? Can anyone tell me is there a relay fuse or not or where can i locate it and can the camera still work if reverse switch is faulty.
