Hallo,
I asked this in the other place but thought it might get a better response here with it being omega only.
My facelift 2000 MV6, the alarm arms (or what I presume to be the alarm, I just mean the flashing light on the main console) but if I sit in the car and move around it goes off, the lights start going but nothing else, no sound.
I've searched through the forums but have yet to find a clear answer, it appears the Omega has 2 diff alarms an alarm and a powersounder, is this correct? What is the difference between the two?
I've located the scuttle, unfastened it on the drivers side and lifted it up. There is only one connection in there that I can see, I have removed and reseated it but no change, just lights flashing, nothing audible. What should I be doing next?
I have included a pic of my engine bay to help and I was wondering if maybe some of the more knowledgable members of the forum could make it into a bit of a template and mark all the frequently named bits on it? We could all use it as a reference item then, it would certainly help me and hopefully others like me who don't have a clue

It's in 2048x1536 so it might open slowly but there is plenty of room for text.
