2002 F-350 4x4 7.3

I have a lighted Lund visor, but I cant find a power source in the fuse box that will make the lights work when the headlights are on?

I had it hooked up to the hi-beam for awhile but they go out on low beam then?
Same thing ,I can find a low beam wire but then they go out on high beam.
I thought maybe hooking them to the dash lights would work but that doesnt work either.

Does anyone know what fuse or what wire I should hook them too?

 

Look for a brown wire behind the driver's side kick panel under the dash.
