How to fix cruise control on a '99 Honda Accord?

I have a 1999 Honda Accord LX, 4cyl, 4 door sedan, VTEC. After repair one day the cruise control didn't work anymore. It was so long ago I don't even remember which mechanic I saw.

There's a screw though on the side of the steering wheel where you can unplug the cruise control plug. Can I just buy a new one from the scrap yard or ebay, plug it in and it will function properly again?

Or is it more complicated than a simple electrical problem? I think the fuse that controls it works fine. Would I need to replace the entire steering wheel or something else underneath the hood?

Thanks.
