ok guys do you wanna hear the good news????????????
The alarm in your cars is not an Alfa alarm. They were fitted at the docks when Alfa imported them before distribution. So first of all you need to make sure the vehicle is a pukka uk vehicle and not a grey import. Secondly if the remote is black and rectangular with two buttons then the alarm is almost definately a Scorpion alarm. I cannot comment on these alarms as I am a DET, BUT I AINT GOT ONE!!!!
Best thing to do would be to check the output to the led at the led connection. For security I will not inform you where the alarm unit is and I trust no one would be stupid enough to post the info on here anyway for all to see. Speak to your alfa dealer in person and ask for info, they will be more than pleased to help.
