I think my sons 99 does as well.

""well i have a 99 and the one in dash and the dic light up when perf. shift is on.""

What is the difference 98-99? i've got a 98 gtp, the bulb in the cluster was burnt out, i replaced it, it works--but how can i get the DIC to light up? is there a wire that's missing from the 98 DIC plug? or something else? and how would i go about fixing that so my DIC perf shift lights up? (everything in the DIC lights up when i turn the key, except the perf shift) how can i get that to light?

Yep, both my 98s had it in the instrument cluster, my 99 has it in the DIC, and honestly I don't remember in my 97 (believe as stated it was in DIC). While I have my 99 torn apart I'll have to throw a bulb in there.

i took mine apart today and the bulbs are for the backlighting. my suspicion is that there is either a wire missing in the harness for the 98's that otherwise lights the DIC perf shift, or...i just have a bad DIC.
If anyone has their digital DIC out on their 99+ S/C'd GP (where the Performance shift works), could you tell me if there are wires in the A5, A8, or B10 pin slots. I'm largely suspecting A5 as a missing wire on the 98s that would allow the perf shift to display. if you do have a wire in that slot, could you trace it and tell me where it leads to? I realize that is a ton of work, but I would greatly appreciate the help.

Here is a diagram of the DIC plug pin positions and what they mean (thanks to backinblack) :
