I have a 91 rs with a 3.1 and the o2 sensor wire is broke about 10 inches after the o2 sensor and I can't find where the wire goes to hook it or a new one back up. I saw in the archives that on an 85 it goes to the D7 pin on the ECM. Could this be where mine goes to? Any info would be great! Thanks! Joe

 

The O² sensor should connect to ECM terminal E14 via a 20 ga. purple wire. You should find the purple wire and single contact WeatherPack connector on the left side of the engine compartment.

 

Thanks Vader! You are a life saver!!! Joe
