Considering the OP's Username is "Snowboard One" I'll assume that you live somewhere where there is snow. Here in Canada, the 110v Engine block heater is standard. It is supposed to be neatly wire tied to the upper part of your engine compartment and tucked nicely on the drivers side. But it should not just be left dangling. I never really use mine, but if I did, in the winter months, I would bring it out towards the front and out the front grill. Then put it back away in the summer.
