I have a 1994 Canadian export STS that needs a new ECM. The P P/N on the ECM is 16195496. Does anyone out there know if this is a common ECM with U.S. Spec cars? Do I need to find this specific ECM P/N? The A/C Delco site doesn't list the P/N, neither does Rock Auto. Any help or suggestions would be greatly appreciated, Thanks!
