I've never seen one that didn't have it, but rather or not if they have been freed up from under the pass. battery/fender well area. Needed to start? That's difference of opinion. My Ohio dealer flat out said (Sales and Service departments) that the Duramax does not need it, nor have it, and what not. Dad reached in, and cut the cord lose and showed them. At that point they wanted to charge a $110 for the option that wasn't even on the window sticker...
