Gauge install dimmer line

Hi guys, about to install a gauge in my M140i and I'm struggling to locate a suitable "dimmer" line to run to the gauge so the brightness is adjusted as and when the headlights come on.

Can anyone point me in the right direction please?

On the 3 series I ran a wire straight from the rear of the boot release switch but not quite so simple on the 1!
