Trying to wire up a bosche sensor I have had sitting here. Anyone know the correct wiring? Thanks
I know I would want water tight wire crimps down there. Everywhere actually but especially down there
Not certain what you need, I have a new Toyota sensor sitting in front of me. Unfortunately the car is elsewhere. It looks like the sensor is on th right in your photo.
Replacement pins and connectors are available.
90980-11178 female
90980-11177 male side
Corsa Technic or Ballenger Motorsports can supply the terminal pins. The Corsa part is: 090IIU-PIN2

I was just going to splice the bosche sensor into the existing original o2 sensor plug and harness. I don’t have the part number.
I bought the sensor 8 years ago and am finally getting to it.
To be honest, I tried one last December and while the short term fuel trims seemed to be doing their thing, the CEL came on and my gas mileage was between 10-12.5 in mixed driving. I o not know what was wrong guessing the polarity on the heater wires was backwards.
I found this 89465-69115 for $89 in Japan. The pigtail is correct for both sides. Put it in and all is well. Gas mileage showed 14.63 over 120 miles of mixed (50% hwy) driving.

Will do thanks for the info. Probably should just redo the entire exhaust. 268,000 miles with 120,000 miles of a constant check engine light I might as well fix it I guess
I had an easier starting point. 234k miles with various CEL - 21, 71, 25/26. 71 drove me nuts until @Malleus got me to stop looking at threads and systematically go through via the FSM. Every bit had an issue, the final one was a VSV problem. The resistance was fine and it did fire, it did not hold vacuum.Will do thanks for the info.

Anyway, it has now gone days without sticking the middle finger at me, so I am off to the knuckles and then this thing is done.

There's no teacher like experience...glad you're all sorted out.
My 94 CEL was on so long was like losing a friend when I finally dug in and addressed the issues. It went bye with a little help from my friends here.
