2007 pontiac g5 domelight supervision

let me start off by saying I have found this site a wealth of information... thank you all who give there time to share there wisdom. I have a compustar alarm that is installed in my car and noticed that the domelight and headlights do not come on when I unlock or disarm my alarm like the factory alarm does. I've been reading up on it and it seems there is a - wire at the BCM that is labeled domelight supervision... can anyone tell me if this wire is the one that will trigger the factory dome light supervision mode? can I connect my domelight supervision output from my alarm directly to it and if so will it also trigger my headlights to come on for a short time? And is there a way to tell if a relay is needed... it seems that some alarms only output a low current for this circuit and can be burnt out.... on second thought I probably should relay it anyhow, better safe than sorry...lol. I have installed a couple of alarms and I do realize that a dvm is needed and I will be sure to check all connections before hand... Any information or comments are appreciated. Thanxs, Corey

If you would like to at least hook up your domelight supervision.. I would go with a relay. The headlights and domelight supervision sound like a factory function or relay of its own. You could probably use 2 relays to drive each circuit. For domelight supervision.. your (-gray wire) At BCM On The Front Passenger Side Of The Center Console can tap into #30 on relay...domelight wire from alarm to #86..12volt constant to 85..and 87 to ground.  I would keep it simple and just hook up the domelight wire circuit.
