So after installing my New headunit I keep blowing my "Battery1" fuse under the hood. The only time it blows is when my lights are actually on though. I dont know what happend? This is in my third gen(05) cavalier. Could it be because I hooked the "brake" wire to the H/U ground? Its just one wire that you hook to the brake so you cant watch TV when driving. They both need to be grounded though?. Maybe a bad switch?


Thats right, keep on killing innocent people and @!#$ everything up for others..YOU ARE TEH WIN

Sounds like something with the lights. There's a grey wire in the stock harness, make sure you're not connected to that.
