Question on trim levels and switches
 

I'm about to buy the base 2006 Magnum SE model. It doesn't have fog lights or automatic on/off lights. I'd like to add them both. If I swap the lighting switch with one that has the option for fog lights and automatic lights, will it work simply via plug and play? Or do I need to have a dealer flash the computer as well? Definitely hoping for plug and play. Let me know if you have an answer!
