I found this with my Spider but put up with it originally and haven't got around to sorting it out. What I found was that running into the alarm you get the memory and the ignition power wires but after the alarm you don't. Not sure if this is an installation error or not but they are fitted by Alfa.

Now I've connected my phone car kit to the loom as well I find that this never switches off. Haven't had any problems so far but can't leave the car un-started for more than a week at a time.

When I go away later in the year I'm just gonna have to disconnect it all.
