I apologize for getting back to you so late. I finally dug the defogger out of storage.

The underseat harness from the switch connector to the blower motor pigtail is 11' 8".
The resistor section is 8'11".
The resistance of the white wire is approximately 4 ohms.
The resistance wire appears to be Nichrome. The purple wire appears to be 16 awg but I'd use 14 awg due to the distance involved.
