I'm planning to swap a d16y8 motor into my automatic civic. I noticed there's only one o2 plug on the ex engine harness. How do I get around this? thanks

The engine harness only has one plug for it because on an EX the CAT is under the car. The o2 sensor wire isnt in the engine bay for the Secondary o2.

And in say a DX the CAT is right after the Exhaust manifold so there is a wire for the sensor in the bay.

What you may have to do is Find the PInouts for the o2 sensor and Run seperate wires to the ECU.

Edit: It right be easier to use the DX harness and just Wire in VTEC.

 

check out the hybrid forums and search around a little bit you might have more luck
