Default Trying to wire up my conversion harness,does the CRX SI have a 4 wire O2 sensor??

I'm in the process of wiring up my conversion harness for obdo-obd1 conversion and I have 4 wires for my O2 sensor-a brown,purple,yellow,grey wires and they are all suppose to go to the 4 wire o2 sensor.I'm waiting on an engine harness so it's not like I can go out and look??

I have a black wire which I know goes to the Vtec solenoid,green that goes to the vtec pressure switch,white goes to the knock sensor (i'm not even sure if I have one of those either????

Any help?? Thanks

Doing a mini-me swap D15B2 bottom and Z6 head and trying to figure out how I'd wire the O2 sensor??? So if I have a D15 bottom and one wire O2 sensor do I not need the 4 wires to the sensor or splice them all?????

depends which ecu are you using..... If you use a p08 ecu then you only need a 1 wire o2 sensor. if you use a p28 then 4 wire sensor.................

It's a chipped P28 isn't there a cheap way out of this like a Mustang O2 sensor rather than the $120 Honda O2???

uh, you're smoking crack.

vtec-e requires a five wire o2 sensor.

d15b vtec should have a four wire o2 sensor.

This thread has to much misinfo in it... If you have a chipped p28, just burn a chip with the o2 heater removed... then you can use a 1 wire o2, and the problem is solved
