I believe this one would work Digi Key Part number: 67-1608-1-ND
White surface mount LED
Note They are 3x the price of the blue ones, and I don't know exactly how well they would work, Good luck with it.
Let us know if you do or have already found an alternative.
from looking at the install instructions for both the 98 and the 02+ power comanders it appears they use the same connector. The one you have should work, you will just have to use a different map in it.
