Got the 3D a week ago. Dealer says the block heater is part of the truck with the cord. I spend a week looking for it and trade 2 emails with the sales guys trying to locate the cord. Finally broke down and went the service manager. Took 2 of us 15 minutes to find the darn thing. It was under the plastic shroud, passengers side, almost behind the headlight. They did a good job hiding that one.
