Be very cautious about that block fitting. If your car has the block heater "freeze plug" already installed, all you need is the cord. If it did not come with the factory block heater fitting installed, you will need a 3/4" hex bit (allen wrench), combined with superhuman strength and the longest cheater pipe you can find. That MoFo is TIGHT.

Make sure that you know exactly what you are dealing with before you go any farther.

Steve.
