Z4 Alarm install instructions 65 73 0 302 424
Just installed the alarm retrofit kit (without interior protection).
Part # 65 73 0 302 424 $112r
Initially wasn't going to add it, but an experience in VA on the way to HC changed my mind.
Basically a under hood switch and a siren with built in tilt sensor.
The siren assembly gets installed underneath the car between the two mufflers.
Instructions say you have to remove the rear bumper cover to do that.
Having the car apart before, that didn't make sense.
Turns out that you just have to remove (8 screws and 2 plastic nuts) the black bottom diffuser
plastic piece cover which gives you the same access that removing the bumper does.
