Had my car for nearly 2 years now. I bought it from J. Dub knowing full well he wanted to make it a track car. He removed a few things, such as the aux box and wiring, as well as the airbag control module and its wiring. Im going to a junk yard tomorrow and will peel apart a 335i until i get what i need. I do not actually know what i am missing except for what i can see from the outside (missing cables, control module). is there anything i should need besides the module and wiring all the way back? Also, is it true the airbag module needs to be coded to the car?
