I've been looking all over. I found DIYs for other cars but not our ours. The directions might as well be in chinese for me. If someone could simplify it for me that would be great.

 

Buy a wideband, weld in the bung, wire as directed.

 

Yeah, wire as directed. No clue. I'm looking for it to be explained alittle better than the directions do. Something to help the lesser knowledged.

 

red wire to 12 volt wire, black wire to ground , other wire to 02 senors(black)

 

where are those wires located?

 

Which A/F Meter do you have?
Is it a real one that came with a wideband? (AEM, Innovative)

or is it just a light gauge one that isn't accurate? (autometer)

 

Its just a light show. Where are those wires?

As already asked, do you have a wideband oxygen sensor installed?

it's not a wideband, comon man dont you know what a lightshow is!? someone who gets an A/F gauge.

 

Those wires come from your O2 sensors plugged into your catalytic converter. I think you need to connect the gauge to the secondary O2 for more "accurate" readings.

 

I have a friend with an 2002 with the four wire o2 sensor and I am trying to figure out which wire to go to at the ECU, and I can't find that anywhere. Again, it's just a light show to fill a hole cause he's sellin the car. I obviously know where the power and ground go, but I don't know what color to hit at the ECU for the o2 sensor signal wire.......and I'm too lazy to trace!!! lol

 

I did it on my 01 civic. the wires attach to your ecu. I will get you a diagram. give me a few minutes.

awesome. Thanks.

 

CAN ENY ONE SHOW ME WERE DO I CONNECT THE AIR FUEL WIRE THAT GOES TO THE ENGINE?IDK WUT WIRE TO PUT IT ON..DOES ENY ONE HAVE A PICTURE OF IT...I HAVE A 4 DOOR 2005 CIVIC.

 

BUMP

 

your primary o2 sensor should have 4 wires, 2 black, 1 white and 1 green. black are grounds, white is heater and green is signal output.

 

My input on this matter would be as beneficial to you .. as a bicycle to a fish. So, I'll just say Good Luck

 

i tried the green wire but its not functioning right all the lights are on in my guage..

 

yea, it probably wont work, the primary o2 on 03-05 is wideband.

 

what if you are using a wideband gauge?

 

i misinformed you. you need the white wire, not green. wideband wont work. the sensors are calibrated differently.

 

based on the wire diagram above do you connect to the primary O2 sensor (6-white, connector A) or something else?
that is my main problem
