O2 help
I had to replace my catalytic converter and the oxygen sensor. The old O2 had seized up in the old Cat.The old O2 had just one black wire to it. I ordered a new Bosch OME Oxygen Sensor and it came with 3 wires (one single black plug….ground I guess) and (one two prong plug white and black). I found where the single (ground wire?) went the ground headed to the DME ground. I would assume that the other two prong plug should go somewhere in the eng compartment. I have look hard for a plug with one green wire and one yellow wire (going by my electrical wiring diagram). I can't even find any wires not being used. Any ideas on were the wire come from that goes to it. Like is it near the eng compartment fuse box???

O2 Sensor connector
This thread shows an 85 with the connectors in the engine bay. The connectors are known to break. Perhaps removed by previous owner? 2 wires are for the heater, green should go to DME. |

I forgot to mention that my car is a Euro. Maybe that why I cant find the yellow and green plug wire.
