figure i get some input to help my decision..... i have a 99 civic dx i recently bought a 95 ls motor, since i put the motor in it has its idle problems and what not lol jus a bad first experience... right now i plan on buying a b20 to replace it, the b18 it has blown piston rings my question is which engine harness would be better so i can avoid many problems from it running right.... i was thinking 99-00 ex harness.... but what about the 96-98 ex harness i have both conversion harness so not a problem there....thanks

 

use your stock harness.. you will need an obd2b dizzy and obd2 alternator and you can use your obd2 injectors from your d-series
