Dome Wire?

[powerstrokesam06]

First of all, I know very little about the wiring of my car. I just bought a set of recon bed lights that came without any directions which was a bit dissapointing so I was just looking for some help wiring them. I want to either hook themto the dome wireso when I turn the cab light on the bed light will turn on so that way I wont need a key in to turn them on. Any help on acessing the dome wire and what it looks like would be greatly apreciated. Or if anyone else has installed these and has any advice...

How about the white lites on the high brake lite (top of the rear cab) assembly??

The dome light wire runs under the drivers side doorsill. I don't remember which color it is but you should be able to find it with a 12v test light.
