As long as it comes out of a manual and has P28 on it, you're good to go. I've converted a few auto ecu's to manual, and it's not tough, but it's also something I'd rather not have to do.
It'll come in:
92-95 Si Hatch
92-95 EX
93-95 Del sol Si

There was also an obd2 version of the p28 found in some of the 6th gen civics and del sol Si's, stay away from them. The plugs are different and won't work for you.
