Changing the D.I.C.

I currently have a '03 gt with the basic driver information center and would like to change it for the one with the trip computer. Does anybody know the part number for it. Also does the '03 have pigtails for both like some other years do. Any help or insight on this would be greatly appreciated.

Like on other year Grand Prixs, the only way to really tell if you have the additional connector for enhanced DIC functions is to remove the dash bezel and DIC. Look behind the DIC wiring harness that extends into the dash. If you have the extra connector it will be included but taped up somewheres back there.
