lets make this as clear as possible
use DX interior harness and DX engine harness
use the "DX to ZC" instructions to setup for multi-point injection(this includes the addition of the resistor box and wires for cyl sensor)
after the "DX to ZC" is complete you are at the same level as the SI harness
then add the four wires(knock sensor, vtec solenoid,vtec pressure switch, and second O2 sensor) and you are done
