it would help to know what year and Body Style you have, as it would make our advice A LOT easier to give. and to Rabbit; I've done some Research of my own while diagnosing my Oxygen Sensor Problem. I have a Wiring Diagram of the Aveo Sedan's Fog Lamp Circuit, and the Ambient Temperature Sensor for the DIC, as well as the pinouts for all of the connectors involved. from what i've seen by looking under Scoots' Dash and Driver's Side Kickpanel, I believe at least the 1LT Aveos are Pre Wired for Fog Lamps all the way to the Underhood Fuse Box. if it would Appease the Court, I can Upload the Diagrams and Connector Pinouts in question.
