I have a 98 civic and I swap the tranny with a 96 ex 5speed. Swap the Harness, intake manifold, and ecu but not I am throwing a O2 code. But the harness for the 96 only had one 02 sensor connector. SO I wired in the 2nd 02 sensor into the ECU, like the book said and the check engine light is still on. So I tracked back the white & Red, Black & White wires back to the green 14P connector and the connector ports are empty. I have tried a new 02 sensor and ECU also with no luck.
Do you think it only has one 02 sensor? OR do you think it is wired in wrong?

Please Help,
