I know.. it will require 3 new wires on the 1990 harness..

- New Knock Sensor
- Power Key reference
- Power Key Light

I need to find the reference values for full power and valet. Also the Light on the 1990 DIC would get rewired. I can use an Arduino if needed to handle the logic change of the power key, if function is to be retained,

then just run Stock 1991 code in the 1990 ECM, I think the 1990 CCM should be able to chat with the 1991 ECM code..
