I just got a bosch universal o2 sensor for my 94 gsr and i cant figure out how to wire it up, if anyone has this on their car or knows how to wire it up can u please help me

 

im pretty sure with the clip facing unpwards, top left is green, top right is white, then the bottom is 2 black, but it doesnt matter which order. try that and see how it works. you shouldnt get a cel. also what i did is just cut off the clips on the old one and connected the new wires so i could use the stock harness. it took like 10 minutes and it works fine. good luck

 

would you happen to know where the o2 sensor wires join the ecu?
i am installing an air fuel ratio gauge and i dont want to run a wire through the firewall.
i checked the service manual and couldnt find what i was looking for.
oh yeah, this is for an obd1 ecu for an integra.

 

eeeh, i'll IM

 

oh sorry if you're talking to me i have no clue, sorry cant help you on that one.

 

On '95 Integra (probably '94 is the same?)

The O2 sensor heater gets power from main relay, not from ECU.
Ground side of the O2 sensor heater is A6
O2 sensor signal is D14
not sure about signal ground, maybe D22?

 

hey Jim
i want to hook up my air fuel gauge to the d14 pinout.
from what i can tell, it looks as if this wire has been cut before, because its taped up,
can i connect my gauge sensor wire there?

 

Yeah, I guess so. Does the taping look like factory or home-made? In my wiring drawing, it shows the signal wire to D14 is shielded. Watch what you do with the shield when you tap into that wire.
