Hi All. Well, feel a bit silly asking, but... Got my 4xe Sahara a few weeks ago. Spec sheets lists an engine block heater. I don't see any sign of a cord for the block heater. Does plugging it in to charge also power the block heater or am I just not seeing the cord? Looked around the battery but didn't see anything. If anyone has found theirs or has info, it would be greatly appreciated!
