So, I've got an 84 300 DT with the block heater. Question is, how do I use it? The plug has a "female" end to it, but anything I plug in the wall has the male end in the wall and a female end to connect to things. So, how do you connect it? Are adapters readily available? After its connected, how long do you leave it "on". Sorry to ask such a dumb question. I've had this car for 3 years, but this will be the first daily driven winter. After the first freeze I can already sense the hesitation! Thanks in advance.
