alarms

Hi Folks I've just bought a 1990 W124 260E with a Serpi Star alarm I wish to disable it without upsetting the central locking system. I have found the control box in the passenger front seat foot well but there are so many wires! Also I don't know what the function is for the key that fits in...

Hi my central locking, windows, seats brake lights do not work, alarm goes when doors opened and engine starts. all fuses and door switches checked, HELP, any ideas it must be a control module but which one??? 1998 E320 Avangard, Any ideas would be appreciated.
