I just purchased and oxygen sensor for my '88 325iC and have a
question. I bought the sensor for a 1990 Mustang 5.0 V8 as others have
suggested. However, this sensor has 3 wires (2 white and 1 black) while
the one currently on my vehicle has four wires (2 white, 1 black and 1
grey). Is this the correct sensor do I just ignore the grey wire when I
swap the connectors? I have the Mustang O2 sensor in my 86 E30 and also helped a friend put a Mustang O2 sensor in a 89 Volvo 740GL. Both cars were the three-wire type. Saved lots of money, $35 vs $150 and the only difference was the CONNECTOR! I am pretty sure that the grey wire is only for shielding or grounding and will probably be OK if left un-connected. I have a Bimmer friend in Virginia who did exactly that with his E30 and his does just fine. I have found that If you wish to solder the BMW connector on the Mustang O2 sensor it helps to REALLY scratch the wires until the copper shows. You see these wires are plated with some kind of shiney metal that doesn't take solder very well. "Watch Out Bosch.... were are learning your merchandising tricks!!!" Hope this Helps.
