Anyone know how to wire a 4 wire norrowband O2 sensor into a 5 wire wideband harness?

I'm slightly scared, what are you trying to do?

Im about to go turbo on my 00 HX wich uses a wideband O2. When i am boosted i will be using a p28 wich does not accept the wideband signal. Therefore I have to use a narowband O2.

your wideband didnt come with a diagram? it should have. you should be able to match that diagram up with your haynes or helms or whatever you use. if you dont have either, you should consider getting both.

He is talking about the Civic HX stock wideband O2 sensor.... not an aftermarket wideband.

I'm sure I can do it.... but..... I'm too lazy to dig into my diagrams right now.....

This is not as hard as you think. Since you are using an OBD1 p28 ECU, all you have to do is locate and tap the pins from that OBD1 p28 ECU, vice trying to do it from the HX harness side. So, what you really need to do is decipher the primary O2 sensor wires from both harness and see if it will require a jumper or a straight up hardwire to the sensor. If you get lost on the HX side of the harness, you can always hardwire all 4 wires from the sensor to the ECU and ground one to the thermostat housing, like what that H-T thread pretty much described..... buy me a couple of packs of Newport and I will decipher that for you if you want..... after I get my Helms Manual from Boostfed
