it does thanks. I just wanted to make sure your 3 wires from your power supply are setup as mine, which is:
Ground = grounded to chassis
Red Constant = direct to battery (15a fuse at battery)
White Switch = to fuse box 10a switch fuse - turns on with ignition.
With this setup i can coordinate windows to sleep. is S3 available under XP or is this strictly under Win7?
