I want to put on some running boards to my screw. I went to the local dealer and the parts guy said they had body colored running boards with lights for the F150s. I've never seen these for the Screws but he said they were for the Screw. I'm going to order a set, is there anything to mounting them? Looks like the holes are predrilled and just have to use the mounting kit. But where I'm hesitant is hooking up the wiring for the lights. Is there a harness I can plug them into or will I have to actually splice the wires? (Never done that before).

Also, will the running boards for the Expeditions fit on a Supercrew?

Thanks
