The install guide says to find a switched +12V source that maintains power during engine cranking. This is where I've come unstuck. The power source in the tissue box area resets to 0 when I've checked with a multimeter and the mobile phone plug behind the fuse box also does this. There is a constant +12V which looks like a direct battery connection but I don't think it should be used for this case (won't it drain the battery?).Just after pointers by others that have installed this particular gauge. The problem with the wires I've tried is that the gauge resets itself when you switch to ACC as well as when you start the engine and then gives incorrect readings (idle is -8 and full boost on an unedited car is reading 10).Any help is greatly appreciated!

LUMO Donating Members 476 Member For: 17y 9m Gender: Male Location: SYDNEY Posted 07/10/08 06:05 AM Share Posted 07/10/08 06:05 AM Ok cool. Well I have a oil pressure and oil temp gauges that are electric and a mechanical boost. My oil temperature and oil pressure gauge have to be installed the same way. I connectted the +12 to a +12 wire near my ignition. (ACC) This is so when I turn the key on (ACC) the gauge has power and when you turn the key off its turns the gauge of also. and it works fine and I done this install on the weekend and works fine. Hope this helps.CheersPete Link to comment Share on other sites More sharing options...
