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 |

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! Larry '92 5.0; Paxton SC |
