O2 Sensor wiring help please

[Scott82]

Ok, i am putting the d15 vtec in my hf crx and am having to use a 4 wire o2 sensor now. In my engine harness there is a Black/Yellow wire, Green/White wire, orange/black wire and a white wire which i added to my stock harness but came out of the Z6 harness which had the 4 wire o2 sensor. Now which ones are the heater wires. I think there are two heater wires, a ground wire and a signal wire. I am guessing the signal wire is the white wire, am i right? Somebody please help. I really want to get this motor in and running by this weekend, but i need to go ahead and get the motor in the car so i can do my suspention work. Thanks Scott

are you converting to OBD1? because if not, you can use a 1 wire O2 sensor, which btw is what a D15B uses in japan coupled with a P08 ECU (JDM brother of USDM P28, only no VTEC pressure switch and 1 wire O2)

i am converting to obd1. i have the p28 ecu, and have all the wires run in the harness that i need now, o2sensor which is not hooked up but the wires are ran, and vtec, and vtec pressure. I have to move my temp sensor wires, and i changed out the Dizzy plugs and injector plugs. I am stoped right now cause i would like to get it wired up before i actually put the motor in the car.

oh and the obd0 to obd1 jumper harness

How did you wire your map sensor. There is three wires on the map and I don't know where any of them go. Im running the p28 ecu on the d15z1 motor and in in an obd0 hatch.
