D15b O2 wiring?
 

I'm gonna be picking up a D15bvtec engine and P08 ecu pretty soon and heard somethings on the ecu that it uses just a one wire O2 sensor or what? If so, what wire do I use on the 4 wire when I wire the 1wire O2 up or does anyone have any suggestions or have they done this?

i dont know if p08 uses a one wire o2 or not but if it does get a one wire o2. a four wire is can be made to work but it would be alot easier to use the single wire.

if your goin to use the p08, use the 1 wire....if you want to run a 4 wire o2, then you would need to get a p28

What wire do I use from the the original harness though to use the 1 wire though? Is there a certain color wire to wire it up to? I'll be using the P08 so thats why I'm asking?

D15B sohc vtec came with 1wire o2 i just bought & installing it right now. thats the next thing i gotta do after i connect all my ground wires & ac.
I don't know how to do 5wire to 1wire o2, so im gonna do a 4wire with mine.
I got a '92 VX - D15Bvtec almost done installing.
Using the stock VX wire & engine bay harness, switching to P28 ecu cuz its easier to convert a 5wire to 4wire and ditch the egr. good luck. i think i saw a thread on here for your wiring question but i can't find what i printed https://honda-tech.com/forums/images/smilies/emsad.gif
