I need to replace the electrolumaneciant instrument cluster in my 98 STS. I have a used cluster that came from a 98 or a 99 with an ID # 25 68 97 89. What needs to be done with this cluster so that it will 'plug and play' when first installed. I have had a half dozen different opinions, all of them different. Who knows for sure what preprograming is required,if any?
