Just get a good chassis ground and run the 12v switched. I have heard of and have on mine a little feedback noise on my AEM wideband. I have tried 3 different sources for 12v switched. A power filter may be needed if it annoys you.
Specifically on ur car I cant say since I am in US and not familiar with the Maloo. But tpically get the aftermarket 'alarm' wiring instructions that an installer would use to install an alarm. That should give you the location and color for the main 12v ign power source.
