I'm looking for suggestions from someone in VIC for help to add an alarm to the existing MPS3 key fob/imobiliser/door unlock. That is, add siren and internal motion sensors and door/boot/bonnet opening alarm.

I had a dealer in Hobart try to install a kit marked as MPS3 compatible, but when it came time to install they found the wiring did not match the instructions, something about a blue wire with white trace being on the wrong connector on the ECU etc.

I'll just have to take the beast across on the boat to a Melbourne place to have one fitted. Has anyone got experience with an installer they'd recommend? I'd like to keep the existing keyfob etc, so want an upgrade not a full new system.

Nov 2006 (first Reg 1/2007) MPS 3 Generation 1.

Cheers.
