So I finally got this figured out. I wired in a 2003+ heating element to my old 2002 harness. The 2002 bottom element has 4 wires coming out of it, two for heating the element and two smaller gauge wires for a thermistor or temp control while the 2003 pad only has two wires for just the element. The temp control looks like two wires tied together with a resistor and it's sealed in between some of the heating elements so I dug that out and transferred it to the new heat pad. Then I cut the old pad off the harness and wired the four wires to the new pad, two to the element and two to the heat control that I buried in the new pad.
I finished off my seat with new foam and new covers and all seems to be working well. Just wanted to post in case there are more 01/02 guys that want their heated seats to work.
