Does anyone know where the main alarm system module and interior motion sensors are located on an e93?

My e93 is pre wired for an alarm system.
I want to pull the alarm system from another e93 but I’m not sure what’s needed.
I have the hood switch and siren.
I have an alarm module/motion detector from an e90, but I don’t think it will work.

Thanks.

From memory i think the e93 is completely different. It uses microwave sensors in the front doors and rear interior side panels, but the e90 uses a ultrasonic motion detector in the roof. The alarm siren module is located above the L/R wheel.

Thanks.
Yea I remember reading it was different and there was sensors behind the panels.
So a total of 4 sensors behind those 4 panels.

I know the siren is in the left rear wheel well, but so is the actual module?

I think the e90 module was part of the motion detector in the dome lights.

In the wiring diagram, the only additional parts it shows are the 4 microwave sensors and the siren.

The E93 is unique (well the E64 has the same setup) in that the alarm module is integrated into the alarm.

I’ve actually considered using the E93 / E64 module in my E90 as it’s not prewired for alarm - considered mounting it in the trunk and tapping into the KCAN currently used by the BMW Assist portion in the Combox.

Anyway, it’s in the alarm siren. Cross references with the E64 (6 series convertible).

Ahh, I see now.
Looking at a photo of one on eBay, I see the siren has 6 wires on the siren and not 2 wires like the other e9x.

Thanks to both of you.

Hello, sorry, I don't know if you can help me! I saw on a forum that you mentioned that you were going to integrate the alarm system of a Bmw E93/E64 into an E90. I installed the entire OEM alarm system on my Bmw E90 LCI m3 and it was very easy even though my vehicle did not come pre-wired. But I was disappointed because the volumetric motion sensor is very unstable and does not work with the windows down, and it caught my attention that you also want to implement the system from an E93 to an E90, have you managed to do it? Or do you know how I can install it on my E90, from what I understand the module that controls the alarm is integrated into the siren, so I investigated the alarm siren has 6 wires, the E93/E64 version and the E90 version has 3 wires, the rest The E93 system has microwave motion sensors but I don't know how to connect them
