Fog Light Installation

i went thru the list twice to make sure this isnt a repost, hope its not

i have a 2004 Xterra, that didnt come with fog lights, so i pruchased the factory fog lights cause i like how those look the most. well i cannot find any wires that are suposed to run to the fogs, and the wire running to my corner lense is not split, and i know i could start from scratch with wiring and a switch (but if theres an easier way, that would be preferred). what is the risk of splicing the wires for the corner lenses?? and if it is hgh risk can anyone help me with the installation info, or paste a link to where i can find the info i need?

any help is much appreciated, thanks

This should help some. You have to run the lines to the battery & put a switch in.

i figured thats what i was gonna have to do, oh well sounds like a saturday project.
thanks
