I have the six fuse panel and unfortunately, I don't have any pics of it installed and the way my truck is set up right now I can't really get any pics of it. But I can show you where it is installed (ignore the red arrow). It is on the firewall, driver's side, tucked pretty close to the corner. It covers that white washer and wedges between the fender and the wires coming through that large firewall grommet.
I picked this spot as it has a decent amount of space there, is close to the battery and a good ground point. It's also decently located spot for roof lights, driving lights, etc. It is a bit cumbersome to hook up new wires in this spot due to reaching over the fender, under the hood, around the hood release cable, around the other cables, etc. but I'm still comfortable with my choice.
