I've been looking around online at old forum threads and see differing answers on the compatibility of the digital overhead console and mirror upgrade. I know it's an old upgrade but I always wanted an R/T with it but mine came with the standard console. I have most of the power options from the factory on mine. It was nice to easily add the power outside mirrors. I haven't tried adding the power seat because my manual one is in perfect shape. I do want to add this digital overhead console over the winter when I'm not going to any car shows. It appears that I will have to get a console already with the plugs for the mirror and the digital computer. However, I'm confused as to what the compatibility is. I know in 2001 they changed the dash. I saw a guy add one to his 2001 on youtube and it worked but he didn't have ambient temp readings because that year was tied into the HVAC controls. It looks like in 1997, 1998, 1999, 2000, and 2001 all had different part numbers for the digital module itself. In 1999 the part number was 56045185AA, in 2000 it was 56045185AB, and 2001 it was 56045185AC when they changed the dash design. So am I correct that only 99-2000 years will work? I'm trying to buy the console, I really only need the module but the ones for sale on ebay don't specify what years they are. Is there a way to tell by looking at the plug? What changed?
