yes the connectors can be switched. the back of the fog light switch is green if I remember right and the defrost is white but the connector for the foglight has a green round sticker on it and it was connected to the defrost switch. I did fix it myself wasn't a problem, I had to hold down the defrost switch to get the foglights to go on LOL, and the fogs were installed at factory. kind of wierd that the dealer didn't see this when the did the PDI on it. anyways they know about it, they never heard about this before.
