I scratched my head on this one too. All cargo lights except the lights you mention, are controlled by the cargo light switch just inside the entry door (along with other buttons for interior and porch light).
I was initially stumped with the reverse of your question - I was wondering how the utility and wet bay lights are turned on. Finally figured out that they are controlled by a rocker switch on the dash and not with the switch for the remaining cargo bays.
