I am having problems finding a good ground on my cavalier...thanks guys

 

the whole car body is a ground,if you are looking for something simple to ground to,try a seat belt bolt,or a bolt from the trunk latch,or you can drill a small hole through the trunk floor and use a nut and bolt,make you sure you know whats on the other side before drilling,there is fuel lines and electrical you can possibley drill into.
