I bought a 99' 3500 dually in Oklahoma, but have since moved home to Wyoming. It is starting to get cold here and I will be needing to plug her in pretty soon. I looked for the block heater plug in cord the other day(just a quick scan really), but didn't see one. Did some of these trucks come without the heater?

Thanks so much, it was right there behind the oil filter. The picture was a great help.

 

No problem !

 

I have had my truck for two years. I was reading a post the other day and went to look, sure enough I had the plug all the time and never even knew it. Does not even look like it has ever been used.

 

I was lucky, mine was right there behind the headlight in plain sight. I'm also taking that as a good sign that the previous owner actually plugged it in during the winter.
