Rear window defroster

Hi, I found that one of the feeder wires attached to the rear window defroster has fallen off (the wire is still attached to the plug the part that the plug plugs into fell off of the grid) Can this be soldered back on? Thanks

A couple of paragraphs down in this article, it tells how to do it. http://autorepair.about.com/cs/doityourself/a/aa112302a.htm
