Ok follow up question. If I had a non fog light Cruze and bought an aftermarket fog light kit and pinned it to the fog light fuse and pulled a junkyard Cruze headlight switch with fog light functionality. I could just plug that junkyard switch into mine without reprogramming the BCM right?

"IF" ? Is that a hypothetically "if," or a your car doesn't have fog lights like the one in your Avatar?
