Just put a y8 into my 96 civic dx...to make things easier we used a new y8 engine harness and my old y7 header/cat....the primary o2 sensor is pluged in and running fine but the second o2 sensor after the cat is pluged into the cat but has no conector to clip into....there is no conector on the engine harness for the second o2 sensor after the cat....does the stock y8 sensor go to a connector through the floorboard and plug into the cabin harness? If so, i dont think i have that connector on my y7 cabin harness. What should i do to send the readins from the sensor to the ecu?

If you are running an OBD1 setup, the secondary oxygen sensor is not needed or used. If you are running OBD2, there should be a connector for it under the passenger seat.

 

which ecu are you using?? if its obd 2 then you would need to run the wires to the ecu

 

im running a p2p in the 96 civic dx w/ y8 motor
the sensor is suposed to plug into a conector near the passanger seat but i dont have the conector on my cabin harness.....honda wants like $240 for a new 2 wire secondary sensor so i think i gotta find a new way to trick the ecu so i dont get a cel light
