1997-2003 Grand Prix Analog to Digital DIC Conversion - Car Forums and Automotive Chat

this is the most AWESOME write up i have ever seen for SPLICING the dic into the car this will work for 98-03 models aswell..but you do need a wiring diagram like the ones posted in the back of the chiltons book for GP's

i also have a couple of the DIC's for a GT only....:-) but i wasn't smart enough to cut the wiring harness to them as well :-(
