When you pop the hood, look around the left side of the engine. It should be all tied up nice and neat. You'll have to snip the plastic ties carefully to uncoil it. I used more plastic clips to wind it through the engine and down the front so I can plug it in through the front bumber where the tow hook installs. Keep it away from moving parts and hot things. I think it also has its' own cover to keep moisture out.
