Cab Mood lighting correct wire

[thedukeofKDY]

Hi guys
I’ve got all the wiring done in the doors and in the footwell for the cab mood lighting and the instructions say to pick up the grey/ blue wire in the headlamp switch to power it but my question is will this put the mood lighting on when the auto lights go on? (Which is what I want). Or will it only turn the mood lighting on when I manually switch to side lights?
Any help greatly appreciated

The grey/blue wire is the instrument lighting so they’ll come on when the dash lights up.
