I wouldn't at all be surprised if the wiring is in place, as it would take WORK not to include it in the same wiring bundle as the Limited. Check it out. You can locate the bundle inside the engine compartment, left side, tucked under the top quarter-panel sheet metal, between the wheel well and the front of the car. The 2 wires in the bundle-of-12 for the fog lamps should be coded pale yellow stripe on pale blue, and a brown ground.

Carefully unwrap the bundle. If you find the yellow-on-blue wire, the pig-tails are likely to be coiled up somewhere down below as they cross the front of the car.
