no
heres all you have to do
you have a 92 and 92s are prewired for VTEC up to the shock towers
either get a 92-95 EX/Si engine harness.... swap the plugs for the distributor, alternator, and injectors with the OBD-2 plugs (get em from a junkyard if you dont have the OBD-2 harness)
or swap the plugs on your CX harness and add the VTEC wires and rewire it to run a 4 wire O2 sensor
or swap all the OBD-2 parts out for OBD-1 parts and rewire your engine harness to run a 4 wire O2 sensor
the P28 will plug right into your car
