Hi i have swap a B16a2 99 Civic Si engine into my 99 EK and i need help wiring the second O2 sensor to my Ecu i wonderd if anyone has done this Swap and could help me fix this. it is the second O2 sensor behind the Cat and it needs to be wired up cause the Si has a body plug and my Ek dont

 

Can anyone help? if you can help do you have 99-00 si wireing diagram. or some type of information that i can use to hook up this 02 sensor

 

Bump for you cause I dont know but someone should.

 

What engine wiring harness are you using?

 

The only O2 sensor you would have to wire would be if you had a DX, LX where the seconday O2 sensor is located under the hood and you were using a 99-00 Si/EX harness. STOP saying EK

find your pinouts and use the plugs and wires from your DX harness to wire it up
