Frank, welcome to TBN, but turn off the caps lock! It's considered shouting, and is harder to read. Thanks.
To have TNT, you need extra hydraulic outlets. I'm not that familiar with the 990, but I suspect you can come up with enough hydro to get TNT. You have to add rear remotes, or maybe one rear remote and also hoses coming off the main valve body if it has power beyond valves on it.
Madreferee can probably tell you more about it, but I suspect you can have it.
Also contact Mark (CCI on here). Look at the Dealers section and find Carter and Carter. He sells TNT equipment and can tell you what you need.
