i searched, and the faq stuff i read stickied at the top is incorrect( it says everything goes to one plug on the strut tower). the car is a 92 cx, jdm p30, jdm b16a, oil,knock, and vtec were previously wired. now the 4 wire o2 needs to be wired up. one heater wire goes to the yellow/black ign. wire on the drivers strut tower plug.(all my wiring info came from metering where the wires went on my 95 ex, and using the helms manual wiring diagrams) the other heater wire goes to orang/black on pass. strut plug, signal out goes to white wire on pass strut plug, and the voltage for signal in goes to green/white that is connected between iat, tps, and ect sensors. does this sound correct and can anyone verify. this is one of my friends cars, hes already been screwed out of a ton of money paying to have things like this fixed and no one has fixed it yet so i volunteered to do it for free. any help is appreciated. and like i said i used the diagram in the helms manual, and i metered all the wires on my 95 ex to confirm, and weve tried 2 different o2 sensors, and i still get code one.

 

Just run it straight from the ecu. expletive a o2 sensor plug, use a boat trailor wiring connector, it's 4 wires

 

observe the connector

 

Look up ecu wiring diagrams. Then you can see which wires go to the underhood wriing harness connector. Because if you do it will save you wiring all the way fron the o0 to the ecu instead of just from the o2 to the connector.I just did this and found out that they dont match colors with the 4 wires on the o2. So go to the junkyard and pich up a couple connectors for the pins. So soilder them DONT JUST TAPE THEM. Its easy, im a wireing noob and I did it fine. If you need help pm me and ill be glad to help you.

 

im not going to the ecu, its prewired to the strut tower already. ive been installing over 10 years i know how to make the connections. thats not what im asking. and ive already looked at diagrams i have the entire engine harness and ecu diagram and hooked it up that way, but im getting code 1. i described how its connected in my op, i just need to know if its correct.

 

would be easiest to get an EX harness, pinouts are

White D14
Green/White D22
Yellow/Black A25
Orange/Black A6

 

so your saying that all 4 wires connect in that one plug? what about yel/blk ign? its in the drivers side plug(checked the manual and metered it out on my car,confirmed.), and the wire between the sensors i mentioned above (checked the manual and metered it out on my car, confirmed)? maybe this manual i got is wrong, or something idunno. thanks for the help though.
