Several questions. Did you special order your Bighorn? If you did and it wasn't an option you ordered it not likely that it's wired. If you bought it off the lot, your dealer should know from the factory invoice as it lists all options. Do you have a bedroom fantastic fan? It's easy enough to check by removing the trim around the square opening and looking for the wires. You will see a set of wires, black-white and ground and they may be taped to a roof joist near the opening.
