OBD1EG6 motor in a OBd2 EK

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

Not sure if this is the info we need?

OBD1 motor into OBD2 car

Method 1

1. Use an OBD2-1 ECU harness with a P28 chipped, P30, or P72 for B18C1
2. Use either an OBD1 B16A distributor with an OBD2-1 dizzy adaptor or swap plugs from your OBD2 dizzy over to the OBD1 dizzy or use a OBD2 dizzy from a B16A or B18C
3. Use your OBD2 injectors
4. Use an OBD1/2 header
5. If not an SI or EX run wiring for VTEC solenoid, VTEC pressure switch and knock sensor (you'll have to run knock sensor on any other models). On B18C1 you'll have to wire up for IAB's also.
6. If your vehicle is an auto or non VTEC you'll have to convert over to a two wire O2
7. Convert over plug on your OBD0 alternator to the OBD2 style (http://img.photobucket.com/albums/v130/fobtions/alt.jpg)

Method 2

1. Use a P2T ECU
2. Use either an OBD1 B16A distributor with an OBD2-1 dizzy adaptor or swap plugs from your OBD2 dizzy over to the OBD1 dizzy or use a OBD2 dizzy from a B16A or B18C
3. Use your OBD2 injectors
4. Use an OBD1/2 header
5. If not an SI or EX run wiring for VTEC solenoid, VTEC pressure switch and knock sensor (you'll have to run knock sensor on any other models). On B18C1 you'll have to wire up for IAB's also.
6. If your vehicle is an auto or non VTEC you'll have to convert over to a two wire O2
7. Convert over plug on your OBD0 alternator to the OBD2 style (http://img.photobucket.com/albums/v130/fobtions/alt.jpg)

Method 3

1. You can use an OBD0 ECU but is not recommended

Danny, get yourself a tunable ECU (hodnata s300) and turn off those sensors. Less work and problem solved

main problem atm is the wiring
we need to a 2 plug wiring not single plug obd1 wiring for the dizzy
