Need help, want to replace AP1 3 channel ABS with 4 Channel AP2 for my road race car. What are the difference and what parts do I need to find of a 2006 or newer AP2 to make it work?? Thanks for help in advance to the S2KI community.

Since no one has chimed in I would look at tech manual electrical diagram to see all components that comprise both systems for abs. Then compare part numbers to see if they changed and acquire all changes. Hopefully it doesn't tie to ecu.
