Does anybody have pictures of the location of the tach wire on a 2003 Cavalier ? Or a good description on finding it. I know its purple and white but having problems finding it. Any help will be appreciated thanks.

On the top of the engine where the ignition module is, you should see a connector toward the driver's side...check there.

If there is a white wire there you can probably use that...also the engine harness, which runs along the top of the transaxle(it's like a 2" split loom harness) has the tach wire in there as well.
