What in the world could this be for?

??? I was working on my truck the other day and I had it jacked up. I then caked it up more to see what it will look like in the wheel wells when I get the 3 inch lift. (I know (Dork)). Anyway. I looked in the front driverside front wheelwell and noticed a blackwire with plastic boxy thing with a cap. At first I thought it was just a computer plug in. I popped the cap and to my amazment it was a 3 pronged AC Plug. It is all corroded and what not mut it is plug as if to plug into the wall. Is this a Block Heater? I have never seen one before. And it is definatly not something I need here in Jersey. Kinda cool though. I am affraid to plug it in though. LOL. Let me know what you all think. :thumb:

Yep, sounds like a block heater to me.

It's a block heater alright........

It's a option you can add on most all trucks.

This past weekend while changed out the front shocks, I found the same thing on my 99 GMC sierra, Tonight i'll be changing the oil, so I can find where that cord goes to. But i'm sure it's a block heater.

Was these an option on the trucks from factory?
