Wiring Assistance

[buckwuk]

So i purchased the Rigid fog lights and rigid sr-q backup light kit. So first wiring question is for the back up lights i was thinking i could wire them into the led box lights in there to have them turn on with my cargo lamp switch. But am not sure if that would be sufficient power or not i suppose i could wire them exactly how the kit tells you to and instead of wiring to the switch wire to the box lights at that point. Also would like to add a switch in the bed for the box lights. And for the fog lights want them to work off the fog light switch which i have seen on here but couldn't find any talk about how its done.

 

So if you could refer me to a good topic or just answer here it'd be appreciated.
