If your headlights will not turn on after the work you did, I guarantee it's the ground. The Cavalier has a negative grounding system, which means, the lights have to be ungrounded to turn on. This means that you cannot just straight ground it to work. When the lights are switched on, this is when they are grounded. When they are switched off they are ungrounded.
If you have a foglight system, you can ground your headlights through them but the foglight switch must be on for your headlights to work.
I had the same problem, so I know what has to be done.
