problems with fog light install

[TiDan]

Has anyone encountered a problem installing the fog lights on the XE. I purchased the kit from the Dealer, I was asked by the parts guy whether I had the off road package or not, I don't. He said it was a different kit for XE trucks with that package.
The bottom line is that My truck does not have the plugs already in line that the new lights are supposed to plug into. I was led to believe by the dealer that all Titans are pre-wired for the fog lamps. Does anybody have an XE that they have installed the Fog lamp kit on that can (no pun intended) shed some light on this problem? If you weren't able to use the factory plugs do you know which wires in the bundle are for the fog lights?
