Pinout on O2 Sensor
 

Hello Technical Geniuses,
I just joined the Forum & hope you wonderful folks can help.
I just acquired a Bosch O2 Sensor w/OEM connector to hook up to my new Autometer Air/Fuel Meter. From the Front, the connector looks like:

when the clip is at the top.

Two white wires go to the top pins, & a black wire go to the bottom pin. Which is the signal, heater, & ground?
My manual's on loan, PLEASE help!

I'm using a 3rd sensor, so as to not interfere w/the signal to the EFI.

TIA, Larry

The first dot is power gnd. second dot is to ignition run . .

and buttom dot goes to the computer - pin 43 for LH sensor, pin 29 for sensor RH

hope this helps

Thnx Slider!!!
Let me get this straight, so I don't mess up. The drawing I made, didn't come out like the connector layout since the extra spaces for the bottom dot didn't appear.

Looking at the sensor connector w/clip at the top:
Left White wire: Power for heater
Right White Wire: Ignition On
Bottom Black Wire: Engine Computer

Thnx again!

Tough crowd.
But I guess it's not the most interesting topic.
