wiring gauges

[Burning Pyro]

ok need a little help plz. i just put in my gauge pod on the a-pillar, now i have 3 gauges, all from prosport, they require a ground, 12 volt ignition line, and a 12v lighting line, where can i find all these close to the a-pillar. theres a red and green wire in the pillar already, the red is the main 12v, and the green still works to light it up also. but correctly though, the guages are suppose to turn on with an igniton switching, a stroke of the key, but also with the lgithing.
