M3 front door speaker connector source and PN

So the last owner of my 2019 M3 ( lease return) butchered the tweeters ( cut the connectors, soldered speaker wire directly to the speakers and crimped the other end) and did the same to the two midrange/woofers in the front doors. What I learned is that the green connector for the woofers that should be on the harness ( mine were cut off) is a special order item and the smallest quantity I could find was 40 units. I used a pulled harness as my reference to get the proper PN. But, I did find a chinese clone of the connector for 72 cents each .. no min buy plus pins from Aliexpress. I also bought the crimp tool just because it was cheap :D

I also ordered some replacement speaker mounting bolts because the jerk who cut the connectors off also used sheet metal screws to "mount" the speakers to the inner liner. My guess is he/she had upgraded the speakers and didnt want to give them to Tesla. It was also during the lock down when they turned in the car so getting experts to do the work was probably impossible or very difficult so they did a DIY job. What a CF.

Anyways.. I'm including some pics for your amusement and I hope this PN may help someone else save several hours of digging
