    Help boost gauge install

    I am installing a Defi D-gauge mechanical boost gauge, and I don't know where to splice the white wire for power. I have the A- pillar off and the bottom of the steering column is removed. I know it needs to be a 12v power source, and was thinking of splicing into the headlights but don?t know which wire to cut. I am also confused about how to get the vacuum line through the fire wall. Any tutorials, advice or pics would be much appreciated. I need some help
