The 04 Lite doesn't care which ends you use, both are compatible, but Straight is preferred on camera side. VTX side can use Straight or 90, depending on how the board is mounted.
The 04 Pro must have a 90 on the camera side to fit through the hole in the camera body. The default is also a 90 on the vtx side, but a straight may also be used on vtx side. I prefer 90 to S👌
