lighted running Boards

Took delivery of my f450 last week and one of the things I had not noticed before ordering was the King Ranch running boards were not lighted as before. I want to add the lights and do not know where /ubbthreads/images/graemlins/shrug.gif to connect the wires to have them light with entry! Any help appreciated! I am also curious about what others have done for auxillary fuel tank installations? Can the uplifter switches be used for that application?
