Automatic Headlights wire for Stereo

[Boosted]

I am trying to wire up my Clarion NX700 head unit so that the Navigation will automatically go to the night setting when the headlights come on. Any idea where i can find that wire? Prefferably inside the cab.

Thanks for any input.

You will need a class 2 interface module as the bcm controls the auto headlight function over the data line

Wow, that went straight over my head. Any more insight into this?

BCM = Body Controll Module . Got it.

I can not find the "class 2 interface module". I have looked for PAC items and do not see such an item.

Maybe my memory is shot...but when I installed my AVIC years ago, I'm almost positive that I was able to tap into a wire on the headlight switch to get a 12v signal indicating that the headlights were on (I don't remember which one...seems like it was 'green'). I'm pretty sure I linked that up to the 'Illumination' line on the head unit and everything worked as you describe.
