E89 Alarm Retrofit

teeboz · 11-06-2018, 10:29 PM

I have a 2010 e89 and want to retrofit the alarm to my car. I had the right door panel off and saw the wiring for the door sensor. My question is has anyone did this retrofit and where can I find the bmw retrofit install docs?

update: i ran into a snag i could not locate the wire connector for the siren after looking on the driver side wheel wall. However i did see a place for the bracket. So the problem in trying a retrofit is no wire harness for the siren.

So... yeah -- I walked this road too, and resurrecting this thread.

Anyone resolve the wiring challenge with this? I see the two horns in blue, the missing siren connector (X) and some other sensor in red...
