Ground on the wire is the outer strand and the positive is the white wire.

I have this hooked up to a OPUS POL

Which wires do they go to on the molex? I got a red, 2 blacks and a yellow. I don't have a voltmeter.

Red = +5v
Black = Ground
Yellow = +12v

You don't need a voltmeter to determine that, just a simple trip to the search tool or Google.

Rodger.
Yellow and black. Now I just have to put a 6 foot piece of wire between them.

Nothing new here, just saying that powering the screen off a Molex or such is pretty sweet. I've got a p4 ready psu running a duron processor so I tapped into the 4wire p4 connector, now I've got auto on/off for the screen.

The pc would have to be on. You could just switch to the cigarette lighter power adaptor when needed. If the power plug on your lilli wont be accessible you could maybe wire a switch so you could alternate between the two - pc power or power from cigarette lighter.

Yea i know that ... but doesnt that defete the object of havin it on the pc power suply.. becoz of voltage drops.. wen cranking

I have mine on my pc power mostly so it turns on automatically when the pc boots. Its also a good steady current but you can run your screen off of the cig lighter just fine even during crank AFAIK. Surviving crank is a pc issue not a screen issue.

Another suggestion when powering your screen off the PC PSU like this is to use a relay to switch the power and use the ign/acc on the dash to activate the relay. Then your screen will be off as soon as you get out of the car and not stay on while the PC is shutting down and obviously attracting attention.
