Adding backup camera to head unit

Hey
I have a 2019 headunit (AIVIB12P0) but no backup camera. :roll:
I want to add a backup camera, but there is no wires in my Leaf.

Head unit has Pinouts for a Camera
Those are:
28 Camera V+ (Y)
29 Camera GND (L)
49 Camera Comp+ (B or G)
48 Camera Shield

Wire diagram says there are following wires for the camera:
1 Power (Y)
2 GND (L)
3 Video+ (G)
4 Shield

My Camera has the following wieres:
Yellow
Whiteish :?:
Black
Red

Im a bit unsure with the colors, so can someone confirm or correct the connections:
Is Yellow Camera V+?
Whiteish cable is L? Camera GND?
Camera Comp+ is black ?
and then Red is the Camera Shield?

Seems like my shematics are wrong and camera might have following wireing:

Yellow Camera Comp+?
Whiteish cable is Camera Shield?
Black is Camera GND?
and then Red is Camera V+ ?

Did you have any success with this?
