JDM rear fog lights - is there existing wiring?

[Lee1971]

I'm really hoping I'm not the first person to come across this....

I have a 2004 JDM Legacy H6 saloon (sedan for any Americans here). On my lighting stalk I have controls for front and rear fog lights (including lights on the dash to show they are on).

The rear light clusters have 2 side lights each side (top and bottom sections). Surely there must be a wire that goes to the rear lights from the fog light switch to be able to use one of those sidelight segments as a fog light?

Has anyone else found this? Does anyone know what colour the rear fog light wire would be? Does anyone have any info?

Thanks muchly in advance

If uk registered has to have rear fog working lights only one side (left side)

Please correct me if I'm wrong.
