The JDM H22 Harness:

Yellow/Black
Green/White
Orange/White
Solid White

And the O2 Sensor:

Two Black

I did a search and I could not find out which one to connect to?

more wiring diagram

 

It's a P13 OBD1

The white wire is leading back to B12 on the ECU?
White/Green wire to D22
Yellow/Black to A2

where does the orange wire go to on the ecu?
also did you have any luck figureing out which wires go to which? Thanks a lot

 

did a little research and found out that :
Solid white wire goes to D4 on ecu
orange/white wire goes to A6 on ecu
the yellow/black wire goes to the resistor box and IAC valve
the green/white goes to the egr lift sensor and the D22 as well

By the way A2 on the ecu is a yellow only wire that goes to injector 4
B12 on the ECU is a white wire going to CYP sensor

Let me know if you want me to scan a copy of the page in the OEM service manuel, it might take a little while, but I can do it. Hope this helps

Oh, and I couldn't, for the life of me figure what wires actually went to the O2 sensor(let me know if you can figure this out), all I know is that in the book the wires go in order as follows:
wht
grn/wht
yel/blk
orn/wht

 

i don't have an exact answer to your question but this may be of some help. On the usdm o2 sensor, the white wire is the signal wire, the two black are heater wires and the green is a ground.

good luck
