The sedan owners have the same dilemma as do the 2007+ FG owners. The 2006 FG owners have a slot where you circled that the K2motor fog light switch goes. If you purchased an OEM fog light kit for a sedan, you'd see that it comes with the entire switch that is a brand new head light on/off stalk. This is the same for the 2007+ Coupe owners. With the K2motor fog lights, you have to be inventive and put the switch either under the dash, or fabricate it directly into that little pocket you circled. You pretty much save over $150, but have to be a little creative about where the switch goes because there's no spot that it fits without modification, or you can dish out the $200+ for the OEM fog light kit from Honda. Keep in mind that the harnesses are different as well. I believe the K2motor fog lights stay on while the headlights are on, but the OEM fog lights turn off when the headlights are turned on. Something like that, someone correct me if I'm wrong.
