Glow Plug ??s

Okay so the check engine light came on on my 2007 F250 Diesel. I took it to Advance and they read the code. P0672-Cylinder 2 Glow Plug Circuit. Is this a sign of a bad glow plug or could it be the wiring? If i were to replace the glowplugs, how hard is it to do? Are they on top of the engine or do you have to take the valve covers off? Also, does anybody know which would be cylinder2 looking from the front of the truck?

Thanks in advance,

On the end of the GP power strip is a connector but this does not have to be disconnected to remove the strip. When you put the strip back on, insert the connectors in their respective holes and push straight down until the connector seats.

I doubt it is the wiring as that is fairly rugged.

Probably just a bad plug.

Just be careful when you put the plug back in to the hole. I know someone ( me ) ,who dropped one of the plugs, and it ended up at a tight space , so I couldn't get it out with a magnet - ended up pulling the valve cover. So just be careful and patient.
