i have an i model and i installed the factory fog light kit and it does replace the light stalk on the steering column.. it was really easy to install everything from the kit.. the instructions are very thorough just like my auto dim instructions and i didn't have any problems installing anything and i'm not the handy type.. but the stalk just replaces the old stalk and it looks great. i'd rather have the light stalk on the steering column then have a switch by the dimmer.. i think it just looks better and that switch from ebay isn't the same color as the rest of the interior.. you can just purchase the stalk from the dealer for $60 and it will work with your aftermarket fogs.
