First determine if the car even has ABS. Just because the cluster has a light doesn't mean it was the original cluster. Look for the ABS pump under the hood. It will have a bunch of hard brake lines coming in and out of it. Follow the lines from the brake master cylinder to find it.

If you confirm it has ABS then check to see if the light comes on when you start it - I bet it does not. Next, check the fuse. If that is OK check the bulb...maybe it burned out from being on for years before you bought it. Once you have done all this report back.
