You do not need to convert to OBD1 injectors. If you keep the resistor box, you can keep the OBD0 injectors. All you need to do is repin the distributor to have matching OBD0 or OBD1 plugs. You will disregard of the 1 wire O2 sensor with my harness and run a 4 wire O2 sensor. The ecu will need to be OBD1 as well. All my harnesses come with a lifetime warranty, killer service and tech support and best of all brand new OEM pieces. My harnesses are even built on the same machine that Honda uses to crimp the pins. All wires are pull tested and beat to death to insure a solid build.Your Harness
