question on an EECIV

I'm not sure, but I believe the differences in the computers had more to do with the model than the year. There are subtle differences between vert computers and coupes as well as differences between automatic computers and 5 speed computers.
 
yeah, need more info. there are SD and MAF puters, auto and stick puters, and then some oddballs of those.

you should look at a schematic for each puter to be sure the function of each pin matches with the harness and other puter.

good luck.
