In a sense - the "resistor" is the wire itself -- a helix of a fine  
copper filament wrapped around some fiber, all embedded in vinyl.   
You'll feel numerous bumps in the blanket itself; these are  
overtemperature fusible links which keep it from overheating if the  
control fails in the "on" position, or you do something profoundly  
stupid like plug in the blanket and turn it on "high" while it's  
folded up inside an insulated box.
