hey guys need some help and advice
my mate has bought a EK civic with a B16a motor
after seeing it we found out that the car is actually running a EG6/9 B16a and still running the CXi wiring harness and was throwing codes for the load detector and O2 sensor
So we went about chaing the harness to a OBD2 EK4 harness
now the problem is on the driver side harness there is 3 plugs but on the OBD1 engine harness there is only 2 plugs we already have a OBD2 engine harness but it seems near impossible to swap the OBD2 engine harness on the OBD1 engine

any suggestions? anyone with previous experience will be great
