Just wondering where exactly the blockheater is located at. Ive got an 03 and an 07, the 03 doesnt have the cord and I havent looked on my 07. Its gettin cold (-4 this morning) and, well, without high idle on the 03 it takes for ever to warm up. When we go it, I got under the truck, under the hood, everywhere looking for the heater and/or cord. I never did see that there was even a block heater in it. So where is it supposed to be on both trucks?? Thanks
