The alarm I purchased is a BMW alarm kit and is compatible with the mm/yr of the car's build date listed on the model tag. I checked that before I bought it and the dealer verified it as well. That said, this car was built right around the cutoff date when BMW changed something related to the alarm system.
The connectors all looked correct when I installed them, but I will go back and recheck. I have to pull things apart again anyway.
Thanks for your reply.
