Up for sale is a complete OEM E46 alarm kit with the siren bracket and complete hardware to make this plug and play. You will just need to enable the coding parameter DWA -> aktiv in the gm5 module and will be good to go. If your clown nose mirror already blinks with the car locked the alarm is enabled. If you are local to the SF Bay Area I can program this for you for a small fee.
