The decoder you have was not made for that Kato locomotive, so it's not going to be a simple board replacement. The loco you have is an older model, so you must now find somewhere other than the fuel tank area to put a speaker and enclosure.
I have two of those older Kato C44-9W models and have not even attempted to put sound into them because of the speaker issue.

Not necessarily. Some folks think the Digitrax sound decoders are too quiet, and an easy way to increase the volume is to use an 8-ohm speaker. And Digitrax says that's okay: http://tsd.digitrax.com/index.php?a=857
