Not really, it does look like an electrical cord, but at the end is just a cap with a clip holding itself together, similar to the clip I saw on the headlight assembly. That said, it could still be that, but the plug/cap looked to small to have an extension cord/AC adapter. It's about 10:30 right now, so I'll give it a closer look in the morning. I didn't see any labels that identified what it was for, it just hangs down on the front left side.
I'm leaning toward the block heater cord, I'm assuming there's some kind of adapter that's supposed to go on the end of it, but again I'll take a closer look in the morning.
