02 sensor wiring question!!

[cmills5081]

Hey guys, soooo I got a quick question...not sure if anyone is gonna know off the top of their head but from searching around a little I couldn't find the answer,

Okkkk soooo after the 02 sensor plugs into exhaust it runs past the valve cover above the heat shield, it then plugs into a connector. The connector has four wires coming from it. Blue, white, red and yellow maybe? (If I remember correctly)

Now I'm wondering which of those wires is the signal wire to the ecu?? Also it looks like it may plug in to another connector to.

But yeah if anyone knows or can find out I'd greatly appreciate the info, thanks in advance fellas!!!

Yellow should be the one that goes to the ECU.

I'm trying to hook up a narrow band I have laying around for shits and giggles just until I got the extra cash for my wideband!!

Not to be a jerk, but a narrowband will just give you a fast and furious light show. It will show lean>rich>lean>rich non stop while driving and become rather annoying. My buddy hooked up one on his 2g and wasted about 2 hours of his life making it look nice and clean only to find it useless.

Lol oh I know it's completly useless but right now I just have an open pod sitting there and need something to fill it just to make me happy. It'll prob only take me 15 mins once I know for sure which wire it is. And hopefully it'll only be in there for about 2-3 weeks or so before I get my wideband

Sooo is the final answer the yellow wire???

I was more or less implying it doesnt matter which wire is the signal because the signal doesnt do anything except make the light dance back and forth. Just wire it up to come on but not read

No - white is the signal wire! Yellow is heater ground.
