Well since I advertised OBD / OBD2 diagnostic service here, I might as well advertise alarm programming service as well.
This is a factory Volvo dealer tool, programming box for Volvo Guard Alarm 2 alarm relay. With it I can change the following settings.
Light signal (indicators flashing) when locking / unlocking - ON or OFF
Horn signal when locking / unlocking - ON or OFF
Horn signal type - Intermittent (BEEP BEEP BEEP) or Continuous (BEEEEEEEEEEEEEEP)
Panic mode (holding down a button on the remote to trigger alarm) - ON or OFF
Auto reactivation (automatic locks doors & activates alarm if no doors opened within 2 minutes after unlocking) - ON or OFF
It can also run a self diagnostic on the alarm relay to tell me if the relay has failed or not.
And last but not least, I can program new remote to the alarm relay with it too, but this can also be done quite easily without the programming box.
Volvo Guard Alarm 2 is pre-wired on all 960's from 1995 (including S/V90) and I believe 850's from 1995 as well.
In some markets it came as standard equipment, such as US and UK.
The reason I haven't advertised this service sooner is because all the 850 & 960 I've seen so far in Australia has aftermarket dealer fitted alarm kits. My guess is back then Volvo Cars Australia had a contract with a local alarm / remote locking supplier to fit all new cars that came into this country. This is not uncommon as Volvo Cars Japan was the same, all the Japanese market 960's I've seen has the same aftermarket kit.
Having said that I've helped a few people in Australia fit Volvo Guard Alarm 2 on their cars, I keep an eye on US & UK forums and whenever someone's wrecking a 960 there I try to grab all the alarm bits. So if you're interested in fitting VGA2 to your 850 / 960 I can certainly help. Personally I think the coolest thing about VGA2 is that the little red LED (on dash speaker grille on 960 & I believe centre of dash on 850) flashes to tell you the doors are locked & alarm is activated!
Here's a photo of what VGA2 relays & remote looks like.

Bottom left to right - remote locking only relay (no alarm), VGA2 remote, starter circuit plug (for cars not fitted with factory alarm or remote locking)
Anyway, same deal as the diagnostic unit, if you have VGA2 and you're in Melbourne you're more than welcome to drop by & use this programming box, I'm on the north side near Essendon airport. Not going to set a fee but any donation will be greatly appreciated!!
