Modern Headlights

I need a fresh set of eyes on this.

On this schematic it shows that the L4 headlamp socket connector is for the Low Beam. The L3 connector is for the High Beam
The L9 conductor is for the ground.

In other words, while looking at the BACK of the headlamp the left connector is the ground and the middle connector is the low beam.

"MY" common sense would tell me that the L4 connector should be the ground.
I guess I have been staring at this too long

I am drawing my as-built schematic for my Duster, so after I die someone will be able to fix it
