I did this mod 2 wekends ago. I used a 1998 GTP DIC into my 2002 GT. The color of the wires did NOT match but i did run them per instructions. And everything works on it except the display never dims. I did the TCS mod where you solder a wire from point a to point b. My TCS light never comes on. BUT thay maybe a blown bulb as every bulb from the GTP was bad.
