Engine Swap/O2 Sensor CEL
Ok, so I swapped my d17a1 out of my dx for a d17a2 and swapped out the engine wiring harness and ecu. So, Anyone that's done this swap probably knows that the o2 wiring for the secondary is on connector E, not connector A.
Connector E is not part of the engine harness, but it's inside the car (and on the ex, part of it must run out to the engine bay for the sensor. Anyways, I need to know where exactly all of the four wires on the sensor plug need to go.
Now, the heater wire and the signal wire go into pin E. The signal wire should go to the wire for the ignition signal. The heater wire connects into the heater wire pin, obviously.
That leaves two wires, a green/yellow and I can't remember what the color is of the other. Anybody got any insight on how this needs to be wired up exactly?

andy, I thought I posted earlier but I guess I didnt actually post it. If you want I can copy all of the pinouts and wire harness diagrams for the a1 and a2 engines out of my Honda book if you dont have them.
