No idea, but could you make this plug into a s2000?

 

What year EG is it? The harnesses for Honda changed in 98, so if the EG changer is from a 97 or older, probably not. A easy way to tell, if it will work if you can't find the year, is see if the changer plug at the end of the changer harness is blue. If it is, it will probably work.

 

Sadly nope, it's not blue :'[ It round like a cable outlet in the back of some CD players.
