Ok, i'm wiring up my Autometer Air/Fuel gauge in my 01 gsr. I just need to know which wire to hook up to by the ECU, for the O2 sensor. (Color/ Pin #)

TIA

 

OMG i was just about to create a thread like this, i really need to know also. right now i have it connected to the o2 sensor on the header, but i dont feel comfortable with wires running all over my engine bay. does anyone know what wire it is on a odbII ecu? it seems like everyone has a odbI ecu, thanks

 

well, i have an ECU pin-out and a wiring diagram, and i remember hearing from somebody that it's a solid white wire. and on the diagram, it shows a solid white wire going from the Primary 02 sensor to the ECU, and all the other wires on the primary O2 sensor, go to other sensors, so i'm pretty sure this has to be it.
Can anybody back me up on this?

 

yea i heard it was the soild white wire on the 3rd connector or something, once im off work ill try it out, and ill let you know how it goes

 

cool keep us updated i'm interested also. But i was runnin mine on my o2 sensor also and not really comfortable with it wires runnin around hehe

 

i just put in my a/f gauge last week, and it's the big solid white one. it's not hugh but u can tell it apart. i think the pin is d14( don't qoute me on that)

 

your right tuco_ruiz its the only solid white wire on the ecu, its on the BLUE connector, the one closest to the passanger seat. and i can tell a difference between wiring the guage from the sensor on the header and directly on the ecu. the ecu is much more stable when it moves, its a lot more consistant. i definatly recommend wiring directly to the ecu.

so basically for the ODBII ECU the o2 sensor wire is the solid WHITE wire on the blue connector. actually the ONLY soild white wire going to the ECU

 

what brand Air/Fuel Gauge are you guys using?

 

im using autometer

 

autometer

 

Autometer

 

I installed my A/F autometer gauge yesterday and I had no luck with the white wire with the red stripe which was the only one

I have an ODB1 and I ended up using the orange/black wire can anyone verify this to be correct for ODB1 cars?

 

well i have obdII and the solid white wire on the blue connector didn't work... so i'm gonna try that other "solid white wire" to the third connector now...

 

its a green wire. i think ppurple auto meter to integra green or white.

 

orange/black is correct, its the 4th wire in

 

lol so which wire is it from obd2 ecu?

 

its the ONLY white one. there are white ones with stripes thats not it, there are white ones with like light silver dots those aren't it either, its SOLID WHITE. SOLID. i'm using the autometer on my 98 gsr so i'm positive .

 

thats right lowrestling.. i finishhed wiring.. its actually not on the BLUE CONNECTOR.. its the gray one.. the last one on the right when lookin at it.. it sthe SOLID white without ne other colors on it...

 

Cool guyz thanks for the info btw, any of you have pic of how that solid white wire with gray connector look like? Actually I just want to see your wiring how you guys hide it and how clean was your install and stuff thanks.

 

go http://www.apexi.com, then go apexi timer documentation. the diagram H-6 or H-2 then you got what you need.
