headlight wiring

I was working on fog lights and attempted to check stuff by touching the main wiring from the fog lights to a headlight wire with headlights on and now my low beam on my drivers head light does not work even after replacing the bulb. I checked fuses inside of car and found none burned out. Does anyone have access to the headlight wiring schematics? PS: my Aveo is a 2007 and I need to fix this asap so I can drive across country to Maine from California on the 3rd of June. Anyone? Thank you, Mark
