Anybody know where the car alarm module is on a S class (W220)?

I would like to make it BEEP when i push the arm button on the remote and flash the signal lights. Right now it only flashes the lights.

The BEEP can be easly done with some relays, but i need to first locate the car alarm module.

Thanks

There are about a half-dozen control modules involved with the alarm system. However, the one control unit that directly controls the alarm siren is the left front SAM control unit. It is in the driver's side front fuse box, in the engine compartment. It is the control unit with all the yellow and black relays and various fuses. Good luck!

Thanks, that is a great help. Did not know that the alarm system on the MB's were that complicated, with so many modules.

Hope i can find the right wires.

Thanks for the help.

I know there is one under the back seat on the passenger side.
