It is winter now and the weather is pretty cold where I live. My battery is weak and there is cold weather on the way, so I decided to test the block heater out. I was told by a friend to plug it in, and then unplug the block heater quickly. If the heat plug had any draw it would create a spark when I unplugged it. It did not create a spark so I figured that the block heater was not working for some reason. I traced the cable and found that it was just dangling at the back of the engine bay. After some research and feeling around the back of the engine, I found the block heater plug.
From the top of the engine looking to the right you can see the orange end of the block heater cable.
Because of the angle, I used a mirror to get a picture of the plug. It now works great, and I still test it regularly by checking for a spark when unplugging it.
