ignition enabled fuse

[agreznik]

Does anyone know what fuse location is ignition enabled? I want to install a GPS with 12 volt socket using a jumper fuse line. All I've tried are power on all times. I want the power to go off when ignition is off so save battery.
Thanks

Most things use a constant and are enabled by the Canbus. I just ran a feed off the acc on my stereo. Its on a 20 amp fuse so it should be good.
