DRL Hamsar Module wired incorrectly

[Snazzy370]

Hi,

I have a 2010 370z that came from the US and was brought into Canada. When a Hamsar 70987 DRL was added they must have connected it to the wrong wire enable line of the unit because the backlight on the radio is off when the headlights are off. If I remove the ground to the DRL unit then the radio lights work fine.

Looking at the main fuse box they've connected the yellow wire of the DRL unit to an orange wire on one of the connectors (orange wire).

Which wire should it be connected too?

Thanks
