There are many. Not sure what you're asking here.

I have an ‘02 330Ci convertible. The main pillar top position sensor broke. I can replace it but I’m not sure in what position it should be installed. I was hoping someone could snap a quick pic of one that is already installed and post it on here. Also, once it’s installed how do you reset the top so all the motors are synched? Put it up manually and start there, or put it down and start there? Any help you can give is truly appreciated.

There is no reset procedure. It is hydraulic and self-bleeding.
