I don't know if zCivic answered your question, but this should help.

 

Well you told me how to twll the ECU, i was concerned with the harness adn engine, but you both gave me some great info.

 

the engine itself will depend on what motor it is......JDM or USDM for example B16A if JDM will not specify A1 or A2 but A1 on the intake manifold will say MPFI on a sticker while A2 will have 3 bars and no sticker..JDM motors also dont use the final #...The ECU prior post from hondata show the ECU's while the car harness would be on a EF 1 large white plug and 2 smaller black ones.
