Not sure if this applies here but ima go ahead.If anyone can help out with what i need to do. we tried to put the green wire to the sensor wires but dont know which ones the signal wire.Thanksheres the wires from the 02 sensor at the headerHeres my wires, red (power), orange (dimmer), black (ground), green (sensorl wire)and here they are lit up at night.

blue wire I beleive is what I tapped into. Mine looks the same, two blacks, a white and a blue.Looks badass! What kinda gauges?

Yeah, that looks awesome, Mike! Wish my car was that cool, I just chopped holes in my little left drawer and got some sucky gauges! When I get rich I'm going to have to buy that set-up off of you! Not sure the color either off-hand without actually going outside and looking at my car, and at almost 2am I don't think I'm going to be able to see much! lol That, and with all the problems I tend to have with everything, I'm not sure you would want to copy what I did anyways!

I tapped into the wires at the ecu plugs.Plug #3, black wire upper left. The one that the purple wire is attatched to.

Hmm, yeah, I tapped in at the plug in the engine bay like Mike is showing, just not sure of the color. Probably 80% sure it is the Blue like everyone has been saying.

are those the cobalt gauges?

Lancer thanks alot... my buddy didnt wanna tap into factory stuff just for later occasions (fixing/selling)but ill see if that works.We tried at the sensor wires and didnt get anything, we poked a hole and touched wires, but nothing.when we touched the negative battery with it the gauge moved?Ill try that and see if it works.And they are prosport gauges from prosportgagues.comI like them alot... but if you ever get them let me know... so i can tell you what stuff you need to get. like the 25$ sender attatchment off glowshift gauges.

Sometimes touching the wont be good enough, youll have to strip a section and wrap the wire around it securely.

Hmmm. well i got all weekend to get two of them running. i have to wait for my attatchment to come in for the water temp.Ima try to strip teh blue wire and do it there. if not then gonna tap off the ecu section.thanks for the help.

What colors do you have on the other side of the sensor plug?

um. i dont know, i didnt check that. i dont know how different in color they are... my buddy just said its better to tap it at the sensor so if i get rid of the gauges and replace the sensor it would look like i didnt mess with it.so we just tried there.

I know why you're doing it there but the manual shows different color wires than your sensor has. I'll go check my car and get back to you...

Well that didn't help... the manual shows black, black, pink and brown as the colors. The car has black, black, pink, white. But, the blue wire should be "heater control." The white (at least in the picture) should be "low reference." The black above the blue wire is "input." The other black is also part of the heater function.

BTW, Lancer's pic might not work for you since they changed the pinouts for '05.

i forgot that too bout the 03-04 difference... thanks.We tested all the wires and ones definately the signal wire... i just dont know cuz i wasnt testing them.Well i have all weekend to mess with it.

OK so i need more help guys... I plugged the signal wire from the gauge to the blue wire in my picture and still nothing??? i dont know what else to do,Ima see if i can get a diagram from online somewheres, if not i may just wire it up to the white one and see what happens, cuz im at a loss now

The blue one should be for the o2 heater control. Not the one you want. Looking at Autometer's directions I think you want the black one above the blue wire since that is the input wire (assuming input to the PCM).

This is the connector view...1-black2-black3-blue4-whiteI believe you want wire #1...

Thats good and bad... bad is i have to clean up the blue wire now... and hopefully the good is it works.ill try tomorrow morning and see if that works, thanks a bunch 2002sportside

No problem. I'm glad the manual came in handy for something. Hopefully it works out for you.

Sorry! I forgot about the plug differance, too. I found it by attaching one end of a long wire to the sensor sender wire then hooked up my multimeter to it. Set it to make the tone and started poking around until I found the wire that made the tone. Took about 20 minutes to find it.

In case you decide to got to the PCM instead...

so it would be #21???Well ima test the white wire tomorrow... if not then ill look into the pcmThanks

Umm, I think it would be #23... I don't think the low reference wire is the one you want, judging by autometer's directions, so the white wire probably won't work.

Looking on 9thgencorolla.com it appears everyone uses the blue wire for the signal. But they all appear to be '04 and older models... MO appears to be down so that was no help. Good luck with this...

Maybe if we can find out what the name of the blue wire on the older Vibes is we can figure out which to use on the newer?!?

I'm working on that... but a wiring diagram for an o2 sensor isn't that easy to find.

No luck on the black wire above the blue one... when i turned the car on the gauge went to the middle then jumped right back at rich (top) and satyed there.Ima look at the PCM after i go to the post office.

i dont know which ones the PCM... heres pics of what i saw in my car...behind gloveboxunder the steering wheel.

Wow, decent pictures of all that stuff, bet that will come in handy down the road!

yeah i tried to get the most and best pics i could... i just wish i could get this **** thing working. i dont understand

Your ECU is accesed from under the dash, under the glove box. In your first, third and fourth pic you have the 'gold' screw that holds it in place in the upper left corner of the pic.There's a cover under the ecu held up by 2 plastic tabs. Just pull hard on those and the cover will hangby the front. Remove the 2 screws and you can drop the ecu to work on it.
