Fyi on the Welcome lights...
wl_KZL is the rear license plate light
wl_sl_2 (I think) is the tail light
wl_NSL is the rear fog lights
wl_NSW is the front fog lights
The correct values for all of these are nicht_aktiv, soft_einschalten, hart_einschalten
I have Welcome lights on my car (which only work when the headlight switch is left in Auto) And I coded everything off, except, soft_einschalten front and rear fogs. Looks awesome!
